22 Extremely Useful And Powerful CSS Tools

Quick Summary

We love useful stuff. For months, we have been bookmarking interesting, useful and creative CSS tools and related resources. We have been contacting developers, encouraging them to improve their tools and release their handy little apps to the public.

We love useful stuff. For months, we have been bookmarking interesting, useful and creative CSS tools and related resources. We have been contacting developers, encouraging them to improve their tools and release their handy little apps to the public. Last year we prepared and published some of them in a series of smashing posts about CSS. Now again is the time to give these tools the attention they deserve. Big thanks to all designers and developers who contributed to the design community over the last months and years. We — our community and the design community — truly appreciate your efforts.

Below, we present 50 extremely useful CSS tools, generators, templates and resources. We did not include “traditional” CSS tools, such as Firebug or the Web Developer extension, but tried to focus on rather unknown tools that are definitely worth a look. Some tools are new and some are old, but hopefully everybody will find a couple of new useful or at least inspiring tools.

Please take a look at the following related posts:

CSS and Typography

  • Hyphenator Hyphenator.js brings client-side hyphenation of HTML documents to every browser by inserting soft hyphens using hyphenation patterns and Frank M.

  • Postable “I absolutely hate having to switch all the ‘< ‘ and ‘>’ signs in my code to ‘<’ and ‘>,’ respectively. I also hate having to write “&” any time I want to include an ampersand. It makes including code snippets on my blog and whatnot extremely annoying, and today I finally got fed up.” This handy tool is a little app that will do all that for you.

This could be useful for both regression testing and assertion-based, test-driven development. Written in Python by Gareth Rushgrove.
