CSS is an integral part of making visually pleasing web pages. As a result, UI/UX and web designers who are fluent in CSS and HTML are in high demand. Whether you are a candidate searching for CSS interview preparation or a recruiter looking for CSS developers, the list of CSS interview questions below will be pretty helpful.

CSS interview questions and answers

1.

When was CSS created, and why?


CSS was developed in 1997 to help web developers explain the visual design of the online pages they were creating. It was created to make it feasible for developers to isolate the functionality and layout of a website's programming from its graphic design, which was previously unavailable.

The contrast between structure and style allows HTML to concentrate on its primary goal — content markup — without having to consider the architecture and operation of the website, often known as the page's ‘look and feel.’

2.

What does cascading mean?


CSS changed the way people think about web design and how they perceive the concept of making a website. Before CSS, components had to be styled in-line or in the head section of an HTML page. This was changed to reflect CSS's cascading form. The following are the three basic processes by which CSS cascades:

  • Components - Multiple elements will share a CSS type.
  • Multiple Styles in a Single Element — Multiple styles can be added to a single HTML feature to create a completely unique appearance.
  • Numerous Pages in the Same Format — To easily achieve template styling, the same stylesheet can be added to several HTML pages simultaneously.

3.

How can you integrate CSS into an HTML page?


There are three forms to incorporate a particular CSS style:

  • You can use style tags in the headline to include your design on your HTML page.
  • You can use inline styling to include your own design.
  • CSS should be written in a separate file and linked to from the HTML tab.

4.

How would you describe an RGB stream?


RGB is a color representation method that is commonly used in CSS. There are three streams in this color nomenclature: red, green, and blue. The intensities of the three colors are represented by values ranging from 0 to 256. As a result, CSS can handle a wide range of colors across the entire visual spectrum.

5.

What are a CSS box model and its components?


The CSS box model specifies the rectangular boxes that are formed and ordered for items in the document tree based on the visual formatting model. Each box has a content area (such as text or an image) as well as customizable padding, border, and margin areas.

The CSS box model is responsible for calculating the following:

  • The proportion of space taken up by a block feature.
  • Borders and margins can converge or collide.
  • A box's dimensions.

6.

How would you describe RWD?


RWD is an abbreviation for Responsive Web Design. This strategy is used to ensure that the layout page looks great on all screen sizes and devices, including smartphones, phones, desktop computers, and laptops. It is not necessary to create different pages for each device.

7.

How can you benefit from using CSS sprites?


When a web page contains many images, it may take longer to load since each image sends out an HTTP request individually. CSS sprites are used to minimize a web page's loading time by grouping multiple tiny icons into a single document. It reduces HTTP requests and hence loading time.

8.

Explain tweening.


Tweening is a crucial technology utilized in all kinds of animation. It is the technique that generates interim frames between two images. Tweening gives the impression that the first image grew spontaneously into the second. CSS3's Transforms (matrix, convert, rotate, and scale) module can be used to achieve tweening.

9.

What is the difference between CSS2 and CSS3?


The fundamental difference between CSS2 and CSS3 is that CSS3 is divided into distinct sections, which are referred to as modules. CSS3 modules are supported by a wider range of browsers than CSS2 modules. CSS3 adds new General Sibling Combinators, which are in charge of associating sibling elements with given elements.

10.

What is the role of an embedded style sheet?


The embedded style sheet helps us to discover styles in a single place within an HTML document. Multiple classes can be constructed using an embedded style sheet for usage on various tag styles on a web page. The details are imported without the need for further downloading.
