External Style Sheet is a
template/document/file containing style information which can be linked with
any number of HTML documents. This is a very convenient way of formatting the
entire site as well as restyling it by editing just one file. The file is
linked with HTML documents via the LINK element inside the HEAD element. Files
containing style information must have extension .css, e.g. style.css.
<LINK REL=STYLESHEET HREF="style.css"
