XHTML Basics

class attribute automatically added to some elements

Every anchor has the following pseudo-classes:

a:link     {background-color:#037; color: white; 
     text-decoration: none} an anchor that has not been visited
a:visited  { background-color:#037; color: white;   
     text-decoration: none} one that has been visited
a:hover  {    background: #fff; color: #037; 
     text-decoration: none;} mouse is over the link
a:active   { background-color:#037;color: yellow;
     font-size: 140%;} in process of being activated

Here is an example:
Oxford Brookes | CMS | Location | Campus Map | Home | News | Equipment
Classes and pseudo-classes can be used together
```
a.external:visited (color:red}
```
Any anchor of class external that has been visited is coloured red
Be careful if you change the font-size that it does not cause the whole page layout to change
