CSS

CSS or CSS3 is fully known as Cascading Style Sheets is what paints your HTML pages with the right colors, look and feel. Some even go to the extent of saying that there can not be a decent website without CSS involved, well, you may have your say of course. Being as old as some of the people you may know, CSS made it's first introduction back in 1996, and has since evolved with time into a couple of variants such as LESS, SASS and SCSS - but the idea is the same - styling for the web!
