What is external style sheet?

[MichaelEthan]

By applying consistent formatting to website pages, external style sheets help in bringing a uniform, global look and feel to a website. The external style sheet can be linked from HTML pages. When using an external style sheet, styles need to be set up only once for each element. The external style sheet contains only CSS syntax and also carries a “text/CSS” MIME type. One of the unique features associated with external style sheets is that they can be created in any text editor, but need to be saved with a .css extension. The file should never have any elements of HTML. There are two main techniques of calling an external style sheet into an HTML document. One method is by using the <link> tag within the HTML document head. Another method is with the help of a combination of external CSS functions along with embedded CSS.
