There are many font testers around that show you what a font will look like before you apply it to your website, but I think that Font Tester is one of the easiest to use.
You enter the parameters for the font and can see the example text change immediately to match your selections.
Once you’re happy with what you’ve chosen, you click Get CSS Code and a new window opens that contains the CSS for the selections you made, gives you the option of setting the HTML element to which it will apply, allows you to name your own class or ID, and shows the HTML of how that CSS class/ID etc. should be written.
Neat. And useful for any web designer who doesn’t already have such a tool in the HTML editor they use. Oh, and it’s free to use!
