Building Responsive Layouts With CSS Grid: A Step-By-Step Guide

How to Build Responsive Layouts Using CSS Grid

A layout in web development refers to how content is organized on a page. It can range from a single column to multiple columns, grids, lists, or a combination of these. When designing a layout, it's crucial to consider the device's screen size. For example, a layout designed for a mobile device should cater to smaller screens, while a desktop layout should accommodate larger screens.

When targeting multiple devices and screen sizes, you may opt for a single, adaptable layout or multiple layouts optimized for each screen size. Simple layouts, like single-column designs, can often work well across various screens. However, more complex layouts may require distinct versions tailored to specific screen sizes.

Responsive layouts are designed to adapt seamlessly to different device types and screen sizes, including desktops, laptops, tablets, and mobile phones. For instance, a layout with three columns on a large screen should be reconfigured to two columns on a medium-sized screen and a single column on a small screen.

Creating responsive layouts was historically a complex task, involving a combination of techniques such as tables, CSS floats, media queries, and CSS flexbox, each with its advantages and disadvantages. However, the CSS grid simplifies this process significantly.

Understanding responsive layouts

CSS grid is a two-dimensional layout system that allows you to create rows and columns. This sets it apart from one-dimensional systems like CSS float and CSS flexbox, which handle either rows or columns but not both simultaneously. CSS grid empowers you to design intricate layouts with ease.

Understanding CSS grid

Before diving into creating responsive layouts with CSS Grid, let's learn about essential terminologies:

1. Grid Container: An element set to display as a grid. It acts as the parent of all grid items.

2. Grid Item: An element directly nested within a grid container. Grid properties applied to the container affect these items.

3. Grid Line: The lines separating rows or columns, define the grid's structure. Grid lines are numbered positively (1 to n) and negatively (-1 to -n) for easy reference.

4. Grid Cell: The smallest unit within a grid layout, bounded by four grid lines. It's where you place your content.

5. Grid Track: The space between two grid lines, either in a row or column direction. Think of them as horizontal and vertical tracks across the grid.

6. Grid Area: A rectangular area enclosed by four grid lines, capable of containing multiple grid cells. Grid areas can span across multiple rows and columns and can be named for easy reference.

Now that we've covered these terms, let's explore some crucial CSS Grid properties.

Key CSS grid terminologies

CSS grid offers a multitude of properties, but let's focus on the most commonly used ones:

Key CSS grid properties

1. display: Determines the grid container's display type, which can be set to grid or inline-grid.

2. grid-template-columns/grid-template-rows: Defines the grid's number of columns and rows. These properties accept fixed values, relative values, or fractions of available space. They can also be set to auto for automatic sizing based on content.

3. grid-column-gap/grid-row-gap: Specifies the size of gaps between columns and rows. These values can be fixed, relative, or a fraction of available space.

4. align-items: Sets the alignment of grid items along the block (column) axis, with options like start, end, center, stretch, or baseline.

5. justify-items: Defines the alignment of grid items along the inline (row) axis, offering options like start, end, center, stretch, or baseline.

6. Fractional Unit (fr): A unit in a grid layout representing a fraction of the available space within the grid container. It's handy for creating flexible and responsive layouts.

For the grid container

1. grid-column-start/grid-column-end: Sets the starting and ending positions of grid items along the block (column) axis. They can be set as numbers, names, or span to span multiple columns.

2. grid-row-start/grid-row-end: Establishes the starting and ending positions of grid items along the inline (row) axis. They can be set as numbers, names, or span to span multiple rows.

3. grid-column/grid-row: Shorthand properties for grid-column-start and grid-column-end, and grid-row-start and grid-row-end, respectively. They can be set as numbers, names, or span to span multiple columns or rows.

4. align-self: Controls the alignment of grid items along the block (column) axis, with options like start, end, center, stretch, or baseline.

5. justify-self: Manages the alignment of grid items along the inline (row) axis, offering choices like start, end, center, stretch, or baseline.

The comprehensive CSS Grid properties list is available here.

For grid items

Now that we've familiarized ourselves with CSS grid terminology and properties, let's create a basic 3x3 grid layout as an example. We'll set up the HTML structure and apply CSS styles.

  .grid-container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-template-rows: 1fr 1fr 1fr;
  gap: 1rem;
}

.grid-item {
  border: 1px solid #ddd;
  padding: 1rem;
  font-size: 1.5rem;
  text-align: center;
}

This code results in a straightforward 3x3 grid with equally sized columns and rows, serving as a foundation for more complex layouts.

Creating a basic grid layout

Now that we've mastered the basics, let's dive into creating a more intricate grid layout to showcase CSS Grid's flexibility. In this example, we'll craft a complex grid with varying column and row sizes, including nested grids.

  .gallery-container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr 1fr;
  grid-template-rows: 1fr 1fr 1fr;
  gap: 1rem;
}

.gallery-item,
.gallery-item-inner {
  border: 1px solid #ddd;
  padding: 1rem;
  text-align: center;
  font-size: 1.2rem;
}

.item1 {
  grid-column: span 2;
  grid-row: span 2;
}

.item2 {
  grid-column: span 1;
  grid-row: span 2;
}

.item6 {
  border: 1px solid tomato;
  grid-column: span 2;
  grid-row: span 3;
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-template-rows: 1fr 1fr;
  gap: 1rem;
  padding: 1rem;
}

.gallery-item-inner {
  border: 1px solid tomato;
}

.item12 {
  grid-column: span 4;
}

The result is a complex grid layout that showcases CSS Grid's capabilities.

Creating a complex grid layout

Before delving into creating responsive layouts using CSS Grid, we must familiarize ourselves with some special units and functions that play a crucial role in achieving flexible and adaptable grid structures. These tools provide the foundation for building responsive grids that respond elegantly to different screen sizes and orientations, enhancing the user experience across various devices.

Special units and functions in CSS grid

One of the most powerful features of CSS grid is the introduction of fractional units, denoted as fr. Fractional units distribute available space within the grid container proportionally. For example, if you define column widths as 1fr 2fr, the first column takes one part of the available space, while the second column takes two parts. This flexibility allows columns to adapt dynamically to varying container sizes, making it an excellent choice for responsive layouts.

  .grid-container {
  display: grid;
  grid-template-columns: 1fr 2fr; /* One part and two parts of available space */
}

Fractional units (fr)

The auto keyword is another valuable tool in CSS Grid that simplifies responsive design. When applied to grid tracks (columns or rows), it automatically sizes the track to accommodate its content. This keyword can be particularly useful when you want a grid to adjust to the content's size, ensuring it remains responsive without excessive manual adjustments.

  .grid-container {
  display: grid;
  grid-template-columns: auto auto; /* Size columns based on content */
}

Auto-sizing (auto)

CSS Grid supports using percentage units (%) for specifying column and row sizes. By setting column widths or row heights as percentages, you can create grids that adapt proportionally to the container's width or height. This approach is ideal for achieving fluid, responsive layouts.

  .grid-container {
  display: grid;
  grid-template-columns: 30% 70%; /* Columns take 30% and 70% of the container width */
}

Percentage units (%)

The repeat() function is a convenient way to specify repetitive patterns within grid templates. It takes two arguments: the number of times you want to repeat a pattern and the size of each pattern. This function is handy when creating a consistent layout with several identical columns or rows.

For example, to create a grid with three columns, each sized at 1fr, you can use the repeat() function like this:

  .grid-container {
  display: grid;
  grid-template-columns: repeat(3, 1fr); /* Three columns, each sized at 1fr */
}

It simplifies the code and makes it easier to maintain, especially when adjusting the number of columns. It's an excellent tool for creating responsive grids with a predictable structure.

repeat() function

The minmax() function is a versatile tool that allows you to define a range of acceptable sizes for grid tracks. It takes two arguments: a minimum size and a maximum size. This function is beneficial for setting constraints on grid tracks, ensuring they remain responsive while preventing them from becoming too small or too large.

  .grid-container {
  display: grid;
  grid-template-columns: repeat(
    3,
    minmax(100px, 1fr)
  ); /* Tracks are at least 100px, but can expand with available space */
}

Understanding these special units and functions in CSS Grid provides the foundation for creating responsive and adaptable layouts. With these tools at your disposal, you'll be well-equipped to craft grid-based designs that seamlessly adjust to various screen sizes and orientations, enhancing the user experience across a wide range of devices.

minmax() function

Creating responsive web designs with CSS grid is a dynamic process that allows us to adapt layouts as per various screen sizes and devices. CSS grid provides several techniques to achieve responsiveness, ensuring your content looks and functions optimally across the spectrum of devices. Let's explore these approaches:

Creating responsive layouts with CSS grid

Media queries are fundamental in creating responsive designs with CSS Grid. By defining breakpoints in your CSS, you can alter the grid layout based on the device's screen width or other characteristics. They allow you to reconfigure the grid for different devices and orientations. For instance:

  .grid-container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
}

@media screen and (max-width: 960px) {
  /* Adjust grid properties for smaller screens */
  .grid-container {
    grid-template-columns: 1fr 1fr;
  }
}

@media screen and (max-width: 480px) {
  /* Adjust grid properties for smaller screens */
  .grid-container {
    grid-template-columns: 1fr;
  }
}

The above example starts with a three-column layout for larger screens. However, when the screen width is 768 pixels or less, we use a media query to adjust the grid properties. The grid is reconfigured to two columns for smaller screens, ensuring the content is displayed logically.

Media queries and breakpoints

CSS grid introduces the concept of fractional units (fr), which distribute available space proportionally. Using fr units, you can create flexible grids that adapt to the container's size. Additionally, you can use auto and percentages to achieve dynamic sizing.

  <div class="grid-container">
  <div class="grid-item">1fr</div>
  <div class="grid-item">2fr</div>
  <div class="grid-item">3fr</div>
</div>

.grid-container {
  display: grid;
  grid-template-columns: 1fr 2fr 3fr; /* One part, two parts, and three parts of available space */
}

In this example, the first column takes one part of the available space, the second takes two parts, and the third takes three.

  <div class="grid-container">
  <div class="grid-item">Lorem.</div>
  <div class="grid-item">Lorem ipsum.</div>
  <div class="grid-item">
    Lorem ipsum, dolor sit amet consectetur adipisicing elit. Ad deserunt
    recusandae dicta ullam vitae quo possimus, veniam, quibusdam eaque
    doloribus animi id unde soluta magnam sed nam quam architecto odit.
  </div>
</div>


.grid-container {
  display: grid;
  grid-template-columns: auto auto auto; /* Size columns based on content */
}

In this example, the columns are sized based on content, ensuring that the grid adapts to the content's size. It helps create responsive layouts that adjust to varying screen sizes.

 <div class="grid-container">
  <div class="grid-item">30%</div>
  <div class="grid-item">70%</div>
  <div class="grid-item">30%</div>
</div>

.grid-container {
  display: grid;
  grid-template-columns: 30% 70%; /* Columns take 30% and 70% of the container width */
}

In this example, the first column takes up 30% of the available space, and the second takes up 70%. This approach is ideal for creating fluid, responsive layouts.

Relative units: fr, auto, and percentages

The grid-template-areas property lets you define named grid areas within your layout.

You can create different layouts by specifying different templates for various breakpoints.

  <div class="grid-container">
  <div class="grid-item header">Header</div>
  <div class="grid-item sidebar">Sidebar</div>
  <div class="grid-item content">Content</div>
  <div class="grid-item footer">Footer</div>
</div>

.grid-container {
  display: grid;
  grid-template-columns: 1fr 1fr;
  gap: 1rem;
  grid-template-areas:
    "header header"
    "sidebar content"
    "footer footer";
}

.grid-item {
  border: 1px solid #ddd;
  padding: 1rem;
  font-size: 1.5rem;
  text-align: center;
}

.header {
  grid-area: header;
}

.content {
  grid-area: content;
}

.sidebar {
  grid-area: sidebar;
}

.footer {
  grid-area: footer;
}

@media screen and (max-width: 960px) {
  .grid-container {
    grid-template-columns: 1fr;
    grid-template-areas:
      "header"
      "content"
      "sidebar"
      "footer";
  }
}

In this example, we switch from a two-column layout to a single-column layout on screens with a maximum width of 768 pixels. The content is displayed in a logical order for smaller screens.

grid-template-areas for different layouts

CSS grid allows you to manipulate the order of grid items, making it possible to stack items for smaller screens or change their arrangement based on content priority. The lower the order value, the earlier the item appears in the visual layout. This is done using the order property. By modifying the order property within media queries, you can control the visual hierarchy of content for various screen sizes, ensuring a seamless, responsive design.

  <div class="grid-container">
  <div class="grid-item">1</div>
  <div class="grid-item">2</div>
</div>

.grid-container {
  display: grid;
  grid-template-columns: 1fr 1fr;
}

.grid-item {
  border: 1px solid #ddd;
  padding: 1rem;
  font-size: 1.5rem;
  text-align: center;
}

@media screen and (max-width: 960px) {
  .grid-container {
    grid-template-columns: 1fr;
  }

  .grid-item:nth-child(1) {
    order: 2; /* Change the order of the first item */
  }

  .grid-item:nth-child(2) {
    order: 1; /* Change the order of the second item */
  }
}

In this example, we start with a two-column layout for larger screens. However, when the screen width is 768 pixels or less, we use a media query to reorder the grid items. The first item (with content "1") is reordered to appear after the second item (with content "2") in the visual layout.

These are just a few techniques you can employ to create responsive layouts using CSS Grid. Combining these methods and adjusting grid properties based on your design requirements and breakpoints allows you to achieve elegant and adaptable layouts. These will enhance the user experience across various devices and screen sizes.

Reordering and stacking grid items

In this section, we'll dive into a complex example to demonstrate how CSS grid can be used to create intricate and highly responsive layouts. We'll combine the techniques and concepts you've learned so far, including the use of special units, functions, media queries, grid-template-areas, reordering, and nesting grids. This example will push the boundaries of what you can achieve with CSS grid.

To start, let's define the HTML structure for our complex layout:

  <div class="main-container">
  <header class="header">Header</header>

  <nav class="sidebar">Sidebar</nav>

  <main class="content">
    <section class="feature feature-1">Feature 2</section>
    <section class="feature feature-2">Feature 1</section>
    <section class="feature feature-3">Feature 3</section>
  </main>

  <aside class="related">Related Items</aside>

  <footer class="footer">Footer</footer>
</div>

Now, we'll set up our CSS Grid to respond to different screen sizes and content priorities:

  .main-container {
  display: grid;
  grid-template-columns: 1fr 3fr 1fr;
  grid-template-rows: auto auto 100px;
  grid-template-areas:
    "header header header"
    "sidebar content related"
    "footer footer footer";
  gap: 20px;
}

/* Styles for grid items */
.header {
  grid-area: header;
  background-color: #3498db;
  color: white;
  padding: 1rem;
}
.sidebar {
  grid-area: sidebar;
  background-color: #2ecc71;
  color: white;
  padding: 1rem;
}
.content {
  grid-area: content;
  background-color: #e74c3c;
  padding: 1rem;
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
  gap: 20px;
}
/* Nested grid within the content area */
.feature {
  background-color: #ecf0f1;
  padding: 1rem;
  border-radius: 5px;
  text-align: center;
}
.related {
  grid-area: related;
  background-color: #f1c40f;
  color: white;
  padding: 1rem;
}
.footer {
  grid-area: footer;
  background-color: #34495e;
  color: white;
  padding: 1rem;
}

/* Responsiveness for tablet screens */
@media screen and (max-width: 960px) {
  .main-container {
    grid-template-columns: 1fr 1fr;
    grid-template-rows: repeat(3, auto) 100px;
    grid-template-areas:
      "header header"
      "content content"
      "sidebar related"
      "footer footer";
  }
}

/* Responsiveness for mobile screens */
@media screen and (max-width: 480px) {
  .main-container {
    grid-template-columns: 1fr;
    grid-template-rows: repeat(4, auto) 100px;
    grid-template-areas:
      "header"
      "sidebar"
      "content"
      "related"
      "footer";
  }
  .feature-2 {
    order: 0;
  }
  .feature-1 {
    order: 1;
  }
  .feature-3 {
    order: 1;
  }
}

A complex responsive layout example

1. Grid template columns and rows: We use grid-template-columns and grid-template-rows to define the grid structure for our header, sidebar, content, related, and footer.

2. Grid template areas: The grid-template-areas property assigns specific areas to each part of our layout.

3. Media queries: For screens with a maximum width of 960px, we adjust the grid to have two columns, with the sidebar and related items below the content items. For screens with a maximum width of 480px, we switch to a single-column layout, with the sidebar above and related items below the content items. We also reorder the feature sections to ensure they appear logically.

4. Reordering: We use the order property to reorder the feature sections for smaller screens logically.

5. Nested grid: Inside the content area, we create a nested grid to arrange the feature sections responsively. We use repeat(auto-fill, minmax(200px, 1fr)) to ensure the feature sections adapt to the available space.

6. Styling: We apply background colors, padding, and styling to enhance the visual appeal of our layout.

This complex example illustrates how you can leverage CSS Grid to create sophisticated and responsive layouts. By combining various grid properties and techniques, you get the flexibility to design intricate web interfaces that adapt seamlessly to different screen sizes and orientations.

Key points from the example

CSS Grid is supported by all major browsers, including Chrome, Firefox, Safari, Edge, and Opera. However, it's always a good idea to check the  Can I Use website for the latest information on browser compatibility.

Browser compatibility

Creating responsive layouts with a powerful CSS grid can result in a versatile tool, but following best practices is important to ensure your designs are efficient, maintainable, and accessible. Here are some tips and best practices to optimize your responsive layouts with CSS grid:

Tips and best practices

Always start with a solid foundation of semantic HTML. Use HTML elements that reflect the structure and purpose of your content. Semantic elements like "<header>, <main>, <nav>, <section>, and <footer>" provide clarity and help assistive technologies understand the page's structure.

Using semantic HTML not only enhances accessibility but also simplifies your CSS Grid layout. By defining meaningful sections, you can apply grid properties to specific elements, making your layout more intuitive to work with.

Use semantic HTML structure

When defining grid areas using grid-template-areas, choose clear and descriptive names for each area. Meaningful names make your code more readable and understandable, especially when collaborating with others or revisiting your code later.

For example, instead of using generic names like "header," "content," and "sidebar," consider using names that reflect the content's purpose, such as "main-header," "main-content," and "side-nav."

  .grid-container {
  grid-template-areas:
    "main-header main-header"
    "main-content side-nav";
}

Proper naming conventions for grid areas

Debugging CSS Grid layouts can be challenging due to their complexity. Here are some techniques to streamline the debugging process:

Grid inspection tools: Take advantage of browser developer tools that include grid inspection features. These tools visually highlight grid lines and areas, making inspecting & debugging your layout easier. Some browsers offer a dedicated Grid Inspector tool that provides detailed information about your grid layout, including grid lines, areas, and item placement. This tool can be invaluable for diagnosing layout issues. An example is the Chrome DevTools.

Check for Alignment Issues: Pay close attention to alignment issues, such as items not lining up as expected or overflowing grid areas. Double-check your alignment properties, such as align-items and justify-items.

Test on Multiple Devices: Regularly test your responsive layout on various devices and screen sizes to ensure it behaves as expected. Emulators and real devices can help identify issues specific to certain configurations.

Debugging and testing techniques

Adopting a mobile-first approach to CSS Grid layouts is an effective strategy. Start by designing and coding for the smallest screens (mobile devices) before progressively enhancing the layout for larger screens. This approach ensures a solid foundation for responsive design and encourages a focus on essential content and functionality.

Maintain a mobile-first approach

Accessible web design is crucial for reaching a diverse audience. Ensure your CSS Grid layouts are accessible by providing appropriate semantic markup, keyboard navigation, and ARIA (Accessible Rich Internet Applications) roles and attributes. Test your layouts using screen readers and other accessibility tools to identify and address potential issues.

Prioritize accessibility

Efficient CSS Grid layouts can contribute to faster page loading times. Minimize unnecessary grid items, use appropriate sizing units (such as fr, auto, and percentages), and leverage browser caching and compression techniques to optimize performance. Remember that overcomplicated grids with numerous tracks and items can negatively impact performance.

Optimize performance

Maintain clear and concise documentation for your CSS Grid layouts. Include comments in your CSS code to describe the purpose of each grid area, explain complex layout decisions, and provide context for future developers working on the project. A well-documented layout is easier to understand, modify, and maintain.

By following these tips and best practices, you can create responsive layouts with CSS Grid that are not only visually appealing but also maintainable, accessible, and efficient.
