I am new to CSS but have managed to convert my page to this satisfactorily from the old HTML format which I had.

I am struggling though with one problem and that I want to have part of a sentence in two different colors; one red and one blue.

In the head, I have got

span.red{ color: red; }

which caters for the red bit, but I cannot figure out what I need to do to get the font to type in blue.

I know that I can do

<p style="color:blue;">blue</p>

But this gives a new paragraph which I don't want.

Any help please ?

Thanks
