Cascading Style Sheet is a web tool that can be utterly necessary if you want to give a professional, qualitative look to your site. It is recommended by W3C , who manages the standards for the Internet, in order to add style (e.g. fonts, colors, spacing, padding, alignment, etc.) to web documents.
The style sheet is more and more used presently due to its usefulness and its advantages that are far from minor: it mainly allows to dissociate the content and the presentation of web pages, which makes them compatible for various browsers, and also
In a sense, nobody is in charge of the web. The web is an open standard, with no restrictions on who can post content, or what that content should be about.

Many of today's Web documents are an odd hybrid of formatting tags, structural markup, and content. Most any document beyond a plain grey page with a few simple headers contains a lot of embedded formatting commands. This inseparable intermixture of style/format with content/structure immensely complicates issues of Web document design. It also represents a potentially costly maintenance "gotcha" for large-scale Web-based document systems.
Style sheets provide a means of separating those formatting suggestions from the structural tags and content of
