Top 30 CSS Interview Questions (2022)
This article covers the most frequently asked CSS interview questions in 2022 for freshers and experienced candidates.
What is CSS?
CSS stands for Cascading Style Sheet. It is a stylesheet language that defines how the elements (or contents) in a webpage are displayed. CSS helps to design a consistent look and feel across all pages of a website.
CSS was developed and is maintained by the World Wide Web Consortium (W3C). It was first released on December 17, 1996. The CSS Working group is currently working with different browser vendors to enforce new specifications in their browsers.
Why use CSS?
CSS enables the separation of the content from the presentation/design. This separation provides a lot of flexibility and control over how the website has to look like. This is the main advantage of using CSS.
What is CSS3?
CSS3 is also CSS, but it is a more advanced version of CSS, and it is also known as Cascading Style Sheets Level 3. Also, if you are guessing that there should be CSS2, you are absolutely right. CSS3 is the successor of CSS2. If we talk about the purpose, CSS3 exactly has the same objective as that of CSS, i.e., to style web pages and make them visually appealing. However, CSS3 does it more efficiently while offering more modern features and better convenience to developers.
The key highlight of CSS3 is its modules, which are documents containing different sets of features of CSS3. In CSS2, there was a single specification document containing all the features. However, the modules in CSS3 make it much easier for developers to learn and use different features for beautifying web pages.
