Now comes my time to give a little back to this community for what I have learned,
I litterally learned this about... 5 minutes ago but it is VERY useful.

If you want to use your own custom font you will need the font file and upload it to your website (in a folder called fonts or whereever you want it to be but putting it in fonts will keep your server tidy.)

in css we need to put this code:

@font-face {
font-family:"customfont";
src:url (/font/"customfont.ttf) format("truetype");

obviously replace custom font with the font you want to use.

the next part would be to apply it to a style since you have defind the font and where it is all you need to do now is:

h1 {
font-family:"customfont";
}

that way anyone can see your website with that font

if anyone notices an error in this, please respond so i can update this post with the correct formula.

that way anyone can see your website with that font

Not until ALL browsers support CSS 3 you won't

hm?
I just tested all my browsers with that website, they all return almost the same (firefox differed the most, just font size...)
Browsers I have:

Firefox
Chrome
Safari
Opera
internet explorer

I dont understand what you ment to show with that website :S

I understand what you mean by not all browser will support it though
surely those browsers will be outdated though and most website will no longer work on them at all anyway so the user will likely upgrade their browser?

Thank you for the tip - I never knew that you could do that.

There is a cool new service that takes case of this for you and you use their library of fonts, so your don't have to worry about proper licensing and fees.

Useful tips UUilliam, though a little too much if associated with some reading about the site performance - (optimization css - optimasi css). Having the smallest outlook.ttf with 18K and the largest times new roman with 400K, is it necessary embed one of them into 20K css file ?. But, I just need your advice if you have a link that can compress that fonts. FMIIW
Greatfull thanks.
