Bootstrap interview questions and answers


What is a breadcrumb?

This is an important Bootstrap interview question. Breadcrumbs are a great way to show how a site's hierarchy-based material is organized. In the case of blogs, breadcrumbs can display the publication dates, categories, and tags. A breadcrumb is an unsorted list with the class.breadcrumb in Bootstrap. The divider is automatically added by CSS.


In Bootstrap, what is the media object and what are their types?

Images, movies and audio can be positioned to the left or right of content blocks using Bootstrap's media objects. The class. media can be used to create media elements and the class. media-objects can be used to specify the source. Media objects can be divided into two categories:

  • .media
  • .media-list


Explain Bootstrap well.

This is an important Bootstrap interview question. The Bootstrap well is nothing more than a container that makes the content appear to be sunk. On the webpage, it can also create an inset effect. A developer can make a well and wrap the content in it with the help of div> and class. Your preferences will determine how the content is displayed.


How do you make navigation elements?

Bootstrap's navigation components can be styled in a variety of ways. All of these .nav files have the same markup and base class. To make tabular navigation or tabs, start by making an unordered list with the .nav base class. It is necessary to include the .nav-tabs class.


What is column ordering in Bootstrap?

This is an important Bootstrap interview question. Column ordering is one of Bootstrap's most exciting features. Using relevant functions, the columns can be easily written in a certain order. You might also move them to a separate column. To simply swap or rearrange the order of the columns, use the push and pull column classes. The Bootstrap grid classes are col-xs-#,.col-sm-#,.col-md-#, and.col-lg-#. The push and pull classes for the Bootstrap grid are.col-xs-push-# and.col-xs-pull-#. This works great for sm, md, and lg sizes as well. Columns are moved to the left by the pull class, while they are moved to the right by the push class.


What are some significant rules that you should follow while using Grids?

When working with Grids in Bootstrap, keep the following three rules in mind:

  • A Column must be the direct child of a row
  • Rows exist solely to contain Columns and are not used for any other purpose
  • Within a container, rows should be placed


How is tooltip different from popover?

The Tooltip component shows as a small pop-up box when the user moves the mouse pointer over an element. When a user clicks on an element, the Popover component appears as a pop-up box. The popover could store a lot more data. By default, the popover will appear on the right side of the element, while the tooltip will appear on the top of the element.


What are the chief components of Bootstrap?

You will often come across this Bootstrap interview question for experienced professionals. The key components of Bootstrap are:

  • Jumbotron: It simply draws attention to a specific piece of content or information by making it larger and more visible.
  • Alerts: An alert is a popup that occurs after a specific action and displays a specified message.
  • Buttons: Customized buttons that are used to accomplish a certain action in a form, dialogue box, or other application. They are available in a variety of states, sizes, and styles.
  • Button group: A button group is a single line of buttons that can be positioned both vertically and horizontally.
  • Badge: A badge is a labeling component that is used to add extra information to a label.
  • Progress Bar: A custom progress bar is used to illustrate the progress of a specific action. Text labels, stacked bars, and dynamic backgrounds are all included.


What is the Modal plugin used for in Bootstrap?

The modal plugin uses data attributes or JavaScript to toggle your concealed content on demand. It also adds.modal-open to the body> to override the default scrolling behavior and creates a.modal-backdrop to offer a click area for dismissing visible modals when clicking outside the modal.


What is the use of the Bootstrap Carousel plugin?

You will often come across this Bootstrap interview question for experienced professionals. A slider can be added to your site with the Carousel plugin. It comes in handy when you need to fit a lot of information into a short amount of space on your web pages. The following are examples of standard carousels:

  • .carousel (‘next’)
  • .carousel (‘cycle’)
  • .carousel (‘pause’)
  • .carousel (‘number’)
  • .carousel (options)
  • .carousel (‘prev’)
