8.2. Theme Customizations in CSS

Cascading Style Sheets

If you're going to attempt to  build a custom theme for a site, you'll need to know or learn how to control your HTML displays with Cascading Style Sheet markup (CSS). There are also a number of tools we recommend you use to speed-up your development.

Recommended Plone theme development tools

• The Firefox web browser
• The FireBug extension for Firefox
• The Web Developer Extension for Firefox
• The View Source Chart Extension for Firefox

Using these tools will allow you to inspect, test, and understand the details of your Plone markup. With these, you can create a CSS file to override what's delivered in your selected theme, allowing customizations that can change your site's visual appearance without having to create an entirely new theme product.
