Hi El Intocable
I've had a look at the code and the code is OK, a quick way to test it is paste it to a text editor like notepad or similar and then save it as a html file, something like banner.html, save it to your desktop and you can check your code by simply clicking on it.
Thats what i did and the font came out the right size, can you have a go your end and let me know what you see by adding a screen shot
should look something like this
The text is the right size, the banner gradiaent and icons are missing as i'm not pointing to your server, but the letters are the right size, theres nothing wrong with the code
