A Font & Style Testing Bookmarklet: FontFriend

FontFriend is a bookmarklet for easily & instantly changing the fonts + styles used on a website without code editing or refreshing.

Once clicked, it overlays a menu with web fonts, font-variants, weights, text-transform properties, size/height entries & an element selector to target specific elements.

At this point, every clicked property instantly updates the selected element.

The overlay screen also has an @font-face support which makes it possible to test non-standard fonts by simply drag'n dropping them.

To sum up, the bookmarklet is very functional for any web designer by removing the standard code editing + refreshing process.
