Linking to Style Sheets


Inline Style Sheets vs Linking to Style Sheets

As previously explained, a style sheet can be defined for a document by enclosing the selectors and classes within a <style> - </style> bracket. This is fine when the styles defined therein are applicable only to the document in which they are included. However, it was also previously mentioned that it is wise to split large documents into chapters and topics, thereby making them more accessible. When a book is expressed in the form of many HTML documents, replicating the styles in the head section of each document will lead to maintenance and consistency problems. Fortunately, the tag <link> facilitates the inclusion of separately defined styles into a document.

Separately Defined Style Sheets

The syntax for including a separately defined style sheet into a document is shown below.

<link rel=stylesheet type="text/css" href=url title="Style">

The specified relationship to the current document is stylesheet, which is further qualified by type="text/css". The url that is supplied is the url of the style sheet document. The url can be a relative or full url, which implies that style sheets can reside on a remote server. The title is advisory and optional.
