is it possible to change the background color and font face ?? instead of the boring white with Times New Roman ?

are talking about windows api or html???

html
<textarea>text</textarea>
that one i tried stuff like <textarea font face="font" bgcolor="#FFFFFF"> but it dont work

CSS should work....
try something like this:
<textarea style="background:blue; color: white; font-family:tahoma">text</textarea>

ciao

cheers
