What is CSS and what does it do?
HTML is just a static and boring document container and CSS works with this markup language to make it look more appealing. CSS mostly works with HTML or XHTML. To make HTML-based webpages development more aesthetic, in 1996, W3C (World Wide Web Consortium) developed the Cascading Style Sheet or CSS. They thought that the presentation of the content should be powerful using layouts, colours and fonts and they were right!
