What is CSS and what are the current version available of it?

Answer 1

CSS stands for cascading style sheets. CSS is used to give styles to your html pages for a website and web applications.

Without CSS, the sites that you use every day would be nothing but a bunch of text strung together to fill up the page.

CSS is critical to giving your sites a nice and modern layout as well as colors and fonts that make your site stand out. CSS also plays a huge part in providing interactivity with sites such as seeing buttons grow or change color when you hover over them.

The current version of css is CSS3 with its predecessors being CSS1 and CSS2. There are currently no plans for a CSS4 and probably never will be.
