formatting text

I’m trying to change the font. Did find and edit the .css file, which First off, this is the plugin of our dreams. Thanks you, thank you.

I am trying to change the style of the text. I found the CSS the plugins>wp-tiles>_inc>CSS>wp-tiles.css. Added font-family: verdana [see below]

Here’s what’s weird. When I view and change in firebug, it all works fine. But when I change in the CSS, no longer works fine. When I veiw in firebug, after installing the new CSS with the change, it doesn’t show up. What am I doing wrong.
