What is CSS? What can it do?

CSS, short for Cascading Style Sheets, is used in presentations to markup the content. It is used to change colour, layout , background, etc. CSS specifies a priority scheme to determine which style rules apply if more than one rule matches against a particular element. CSS information can be provided by various sources. CSS style information can be either attached as a separate document or embedded in the HTML document.

CSS saves us a lot of time if we need to change many pages at once. This gives priority to the rule and all pages will be changed instantly instead of manually chang 1 page at a time. Like a Html, CSS also uses computer language such as the colours which you want to choose must be in code. CSS is not widely known but it can actually be a great help.
