CSS is used to how html elements are to be displayed on the web.
We use css to define style to our web pages like in terms of design, layouts and display in different devices.
HTML alone is not capable to style its web pages, we can use some tags to describe the content of web page. In HTML 3.2 some new tags are added like font and color attributes. But for large websites which have number of web pages it is very hectic.
World Wide Web consortium (W3C) introduced CSS to improve web presentation. To allow web designers to define the look and feel of their web pages.
Note: All the modern web browsers support all of CSS Level 1, Level 2, and Level 3.
