10 Useful Bookmarklets for Web Designers and Developers

  • Tom Kenny

You may not be aware of bookmarklets which are an underused tool in web designer or developer’s toolbox. A bookmarklet is a a term that merges bookmark and applet to add functionality to a web browser. They can be stored in the bookmark bar of any browser and used from there to perform useful tasks and consist primarily of Javascript code.

As Javascript is synonymous with web development, some clever developers have created some extremely helpful bookmarklets that can improve your day to day work. Here are ten of the best available.

1. Firebug Lite

All web designers and developers should be familiar with Firebug (if for some reason you’re not then go now) and Firebug Lite is a striped down version that works on all browsers. Especially useful for fixing IE issues.

Interesting fact: Firebug inspired the name for Inspect Element.

4. Resize Viewport

Very simple, click on the following links to resize your browser window to these common resolutions. Only works in Firefox but that’s most of you who read Inspect Element.

1024 x 768 | 1280 x 1024 | 1440 x 900 | 1680 x 1050

5. ReCSS

One of the most useful bookmarklets for development is ReCSS. It reloads the CSS file independent of the HTML which speeds up work considerably when you’re only writing CSS code.

7. Edit Current Website

Sure, you can preview edits of HTML text using Firebug or WebKit’s Web Inspector but this bookmarklet turns the whole page into a WYSIWYG editor. Of course these changes aren’t permanent and are only local to your machine but gives you a good idea of what changing content does to the page.

8. XRAY

Similar to Firebug Lite in that you can inspect elements on a page but much clearer to see what you have selected. Also seems to be quicker.
