CSS can perform pixel-level precise control of the layout of element positions in web pages, supports almost all font size styles, and has the ability to control web page objects and model style editing capabilities.

Before CSS, almost all presentation properties of an HTML document were contained in HTML markup (especially in HTML tags); all font colors, background styles, element alignment, borders, and sizes had to be in HTML explicit description.

As a result, the development of large websites becomes a long and expensive process as style information is added repeatedly to every page of the website.

In order to solve this problem, the World Wide Web Consortium (W3C) introduced CSS in 1996 and maintained its standards. CSS aims to achieve separation of presentation and content. Web designers can now move a web page's formatting information into a separate style sheet, which makes HTML markup simpler and more maintainable.
