kerning.js gives you full control of your text. Set precise spacing, change size of specific letters, change colors of specific letters. There's a ton of possibilities if you know how to write CSS.
Perfect for those of us with OCD.
Note using kerning.js is not for novice users. You should have a full understanding of CSS and HTML to use this. It takes some crafty CSS and HTML coding to make it work within a Joomla template.
