Firebug: the best-spent 6 minutes.

Note : This snippet applies to Customizr version 3.1.x and below. It may not work with version 3.2+. Use with caution on 3.2+ and check the availability and type of the hooks in the Customizr hooks API.

Updated 8 June 2014, to add links to some great articles.

Many problems that are asked on the Customizr forum are very easy to solve using Firebug. For every element on your page, it quickly and easily shows you which CSS rules (and files) are responsible for the styling.

You can work out in seconds how to change the styling of any element. Simply right-click it and select Inspect Element with Firebug.


Firebug works with Firefox. Other browsers have similar tools:

  • Chrome has its Developer Tools.
  • Safari has Web Inspector (which you switch on in the menu with Safari > Preferences > Advanced > Show Develop menu in menu bar). Simply right-click and select “Inspect Element” to launch it.

But my favourite is Firebug. I find it more user-friendly and less complex for a first-time user. Once you get more confident with it, you’ll find some really great features that take you to another level.
