Web source files

The source of a web-page is a file encoded in the HTML (Hyper Text Mark-up Language) format. This section gives a brief introduction to HTML using the library documentation web-page as an example.

An HTML file is an ordinary text file using a special syntax. Certain characters like <, >, & and “ are delimiters defining the syntactical structure. The file consists of elements of the form <…> intermixed with text to be displayed. The following construction will for instance make a button with a link to a web-page:

<a href="http://msdn.microsoft.com/en-us/library/ee353439.aspx"> active pattern</a>

The text:

active pattern

is displayed in the button and a click will cause the browser to select the web-page given by the URI:
