Smashing Magazine - we smash you with the information that will make your life easier. really.

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.

We strongly encourage you to develop these tools further, build on the ideas presented here, release new tools for the public and let us know about them. We would love to feature your handy tool in our next review.

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.

The goal is to provide hyphenation in all browsers that support JavaScript and the soft hyphen for at least English, German and French. Here is the server-side script that does the hyphenation.
• CSS Type Set
  CSS Type Set is a hands-on typography tool that allows designers and developers to interactively test and learn how to style their Web content.

  Typechart lets you flip through, preview and compare Web typography while retrieving the CSS.

  

• CSS-Typoset Matrix and code generator
  A matrix table that presents font sizes and (symmetrical and asymmetrical) margins for various base font sizes — in pixel and em units. It also generates the source code on the fly. Created by Jan Quickels.

• Facelift Image Replacement (FLIR)
  Facelift Image Replacement (or FLIR, pronounced “fleer”) is an image replacement script that dynamically generates image representations of text on your Web page in fonts that might otherwise not be visible to your visitors. Written by Cory Mawhorter. How To Use Any Font With FLIR: Tutorial.
• Vertical rhythm calculator
  This tool converts pixel values to em values depending on the font size of the text. You can also set margins and paddings automatically, depending on the line height you’ve defined. Very useful.

  

• typeface.js
  Instead of just creating images or using Flash to show your website’s graphic text in the font you want, you can use typeface.js and write in plain HTML and CSS, just as if your visitors had the font installed locally.

CSS Online Tools

But the really special thing is that you can do these things as you would with regular CSS.
• px to em
  This tool is what its developers call “px to em conversion made simple”. Type a base font size in pixels, and the tool will produce a complete pixel to em conversion table, making elastic Web design much easier to produce.
• CSS Frame Generator
  This tool returns corresponding CSS in a line-by-line way indented with spaces to reflect XHTML structure – each selector and all of its properties and values in one line. This may be a bit strange for you at the beginning, but if you get used to it you’ll find it much better.

  

• CSS Redundancy Checker

• 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. Created by Elliot Swan.

  

• Kotatsu
  Kotatsu is a simple HTML table generator. The tool lets you attach classes to cells in the same column easily.

The tool has been optimized for Fluid, the Mac application that creates SSBs (site-specific browsers) for websites.

  

• CSS Evolve
  CSSEvolve lets you play with many properties of a website, including the website’s color scheme, fonts, borders and more. CSSEvolve works through a process of simulated evolution in which you select website features that you like and refine them through multiple generations.”It uses a traditional blind watchmaker, user-driven genetic algorithm to drive CSS changes on a website of the user’s choosing. Basically, a set of mutated CSS variants are produced, the user selects changes that he or she likes, the algorithm randomly combines those changes through crossover and mutation and the process continues.” [ via ]

  A Web app specifically designed to help JavaScript and CSS folk test snippets of code in a particular context and debug the code collaboratively. It allows you to edit and test JavaScript and HTML (reloading the URL also maintains the state of your code: new tabs don’t). Once you’re happy, you can save and send the URL to a peer for review or help. They can then make further changes, saving anew if required. Alternative: CodePaste or EtherPad.

  

• CSS Text Wrapper
  The CSS Text Wrapper allows you to easily make HTML text wrap in shapes other than just a rectangle. You can make text wrap around curves, zig-zags, or whatever you want.

  

• Writing Tests Against CSS
  CSS is hard to test automatically. Do font sizes meet expectations? Does the layout width correspond to the initial mockup? This tool helps you spot changes in unexpected areas of a website’s layout and design. It can also extract rendered DOM values, such as text size, from a given Web page and compare them against expected values. This could be useful for both regression testing and assertion-based, test-driven development. Written in Python by Gareth Rushgrove.

Handy Kits For Designing With CSS

• Regex Patterns for Single Line CSS
  If you are formatting your CSS style sheets single-line, you may find Dan Rubin’s Textmate macro useful and helpful. “This macro retains a single blank line where your original contained two or more blank lines (helpful if you group your rules) and adds white space that matches my standard formatting preferences (which I find makes it easier to scan quickly).” And if you don’t use Textmate, you can use a regular expression instead; it is also provided in the post.

  A Firefox extension (for v1.5 or later) that finds unused CSS selectors.
