What is CSS?

CSS stands for Cascading Style Sheets. CSS code, stored in CSS files, is used to define the styles that determine the appearance of elements within your site pages. Different levels of headings, for example, could be defined using H1, H2, H3, or H4 styles. The overall appearance of website themes supplied by Wild Apricot is controlled by CSS (and an extension of CSS called LESS) stored in Theme.css (or Theme.less) files.

Customizing CSS

You can customize the CSS used to control the appearance of your site in several different ways:


Only full administrators or full website editors – not restricted website editors – can access the Colors and styles screen or the CSS customization screen.

The settings you choose on the Colors and styles screen are stored in a CustomStyles.css file and will override the CSS in your theme. The CSS code you enter within gadget, layout, and placeholder settings, and on the CSS customization screen, is stored in a User.css file and will override both the theme settings and the CustomStyles.css file.


You can also customize your site by modifying or replacing individual theme files. For more information, see Theme overrides.

Entering CSS customization code

To enter CSS customization code, follow these steps:

  1. Under the Website menu, click CSS.
  2. In the Editor field, enter the code for your customization.
  3. To check for errors in your code, click the Validated customized CSS link or click the checkmark icon beside it.

  4. Click Save to preview your customization within the preview area on the right.
  5. When you are finished making your changes, click Cancel.

Instead of entering CSS code here, you can use File management to upload a CSS file containing multiple customizations to the Resources folder.
