Google Reader Font Size
These days, Google Reader is my feed reader of choice, web-based or otherwise. It is, in my opinion, the perfect compromise between traditional three-paned apps and Winer's River of News approach. My one complaint, however, is the lack of a font size preference. Yes, I could change my browser preferences, but the larger font makes the tag tree pane look cluttered.
I hacked around the problem using Stylish, a handy Firefox add-on that allows per-site CSS tweaks. Here's the code block for larger entry text in Google Reader:
@-moz-document url-prefix("http://www.google.com/reader/view/") {
.entry-body { font-size:150% !important; }
.entry-title { font-size: 125% !important; }
}
