line-height vs. font-size/line-height
css, font-size
Solution
First of all, you have `font-size: 14px/19px;` which is invalid. I think you mean `font: 14px/19px;` But this is still wrong...
When using the CSS shorthand for font, you cannot omit the size or family values.
Try `font: 14px/19px Arial;`

Problem
If in a font-size: CSS attribute you encounter font-size: 14px/19px, that's the same thing as saying font-size: 14px; line-height: 19px, isn't it? If so then why aren't the following two paragraph tags the same height?: http://www.frostjedi.com/terra/scripts/demo/line-height.html
