This page www.teamspeakdisplay.com (Username: user / Password: teamspeakdisplay) uses a font that I downloaded it from the internet, and when I view it on my computer it obviously looks just fine.

You guys should notice that when you view the site, the title is pushed WAY over to the right, and its also a regular font(arial or something)

The site is valid xhtml, so how can I use my custom font on the site?

You really can't, at least not natively or with CSS. I would suggest you look into sIFR, it's pretty easy to set up and you can use any font you want, and the user doesn't have to have that font at all.

You either have to make your text graphical images or use Scalable Inman Flash Replacement (or sIFR).

wow... not like it was back in the day when you could just embed a font huh?!

You can still do that, but it only works (sort of) in Internet Exploder.

use Scalable Inman Flash Replacement (or sIFR).

I believe I DID say that - and images shouldn't be used for text.

Here is the list of websafe fonts that I use in my own personal web development.

font-family: 'Arial Black', Gadget, sans-serif;
font-family: 'Bookman Old Style', serif;

font-family: 'Courier New', Courier, monospace;
font-family: Garamond, serif;
font-family: Georgia, serif;
font-family: Impact, Charcoal, sans-serif;
font-family: 'Lucida Console', Monaco, monospace;
font-family: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif;
font-family: 'MS Sans Serif', Geneva, sans-serif;
font-family: 'MS Serif', 'New York', sans-serif;
font-family: 'Palatino Linotype', 'Book Antiqua', Palatino, serif;
font-family: Symbol, sans-serif;
font-family: Tahoma, Geneva, sans-serif;
font-family: 'Times New Roman', Times, serif;
font-family: 'Trebuchet MS', Helvetica, sans-serif;
font-family: Verdana, Geneva, sans-serif;
font-family: Webdings, sans-serif;
font-family: Wingdings, 'Zapf Dingbats', sans-serif;

I dont think i want to get as involved as sIFR.
I took a look at it, and its alot of stuff, just to use a custom font on my titles.

I think i might just make a banner instead, then find a different font that still looks good for the other titles.

It looks like a lot, but it's really easy

Take a look at the code for it at www.fpash.com - the "Walk ins Welcome" message at the bottom is sIFR.
