font type

How to change the font type?

I want Airial or so, that everybody have.

But now it's not beautiful on my site...

The fonts are specified in default.css. Just search for font-family

did you have a look at your site with several browsers?

if not you should before you make any changes that you regret...

sometimes the browser font overrules the site fonts.

What i have seen on your site is that you make use of lots of different font-family in different modules.

What can i do?

Can i add something on the default.css that overide all modules & browsers?

check the modules css files and see if they look to base css of uni template that you use.
if the modules use own font-fam. you could change that.

if you want your site to look good and clean then put some extra time into it..

It will be wurth it!! :-)
