Changing font background colour..?

[sanc]

Hi
I've got a small prob (again) which I can't suss.
What I want to do is change the colour to the background to some text.
What I mean is, you know when you left click with the mouse and drag over text, the background for that text changes, well I would like this effect for some of my text i.e. different colour to white.
I'm using some CSS to define size of text to all text but is there away to define the background colour for text, but not all the text.
Hope someone has a solution CSS or other means.
Thanks again sanc

Do you mean that the background color changes on a mouseover

This can be done like this:

<a href="">text</a>

And then your css:

a:link
{
  background-color: transparent;
}

a:hover
{
  background-color: white;
}
