Top CSS Interview Questions Every Developer Should Know

Every industry is seeing an increase in web applications and websites. CSS or Cascading Style Sheet is essential in developing websites. Today, there is a huge demand for web developers who are experts in HTML and CSS because they tend to create cutting-edge and fashionable designs. CSS style sheet manages how the page's elements and contents look and are displayed. A uniform look and feel is created for all the pages using CSS.

The World Wide Web Consortium (W3C) developed and continues to manage CSS. It was initially made available on December 17, 1996. To add/enforce the new feature / specifications in all browsers, the CSS Working Group is currently collaborating with various browser vendors. The content and presentation can be separated using CSS. This division offers a great deal of flexibility and control over how the website must appear. This is the primary benefit of CSS.

The 3rd version of the CSS standard, CSS3 or Cascading Style Sheets Level 3, is used to design and format web pages. CSS2 is incorporated into CSS3, along with some upgrades. The division of standards into various modules, which makes CSS3 simpler to learn and comprehend, is the primary change in CSS3.
