Use pretty fonts everywhere: a bookmarklet to use any system font on any page

I use Instapaper all the time, and I love it. It is beautiful and simple and elegant and wonderful.

All Instapaper needs is some options for alternative, elegant fonts, to add a little spice to an other repetitive reading experience. There are lots of ways of loading in your own CSS on most browsers (user specified CSS through preferences, Greasemonkey, etc.), but I like the ease and flexibility of bookmarklets. It is especially handy to have your bookmarklets follow you around if you use multiple computers: sync with either XMarks or Mozilla Weave.

Given this need, I’ve made a very simple bookmarklet that uses jQuery (hosted on Google’s CDN) to swap the HTML body font-family for Lucida Bright (although any font available on your system is possible). The jQuery is added using the “jQuerify” bookmarklet suggested by Resig himself, and the jQuery command is dead-easy.

To install simply drag System Font to your bookmark toolbar.

To customize simply click on the properties of the bookmarklet and change ‘Lucida Bright’ to any font name you have available on your system
