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.
