If you need more control over the customization of your pages on itch.io you can request access to the CSS editor. CSS customization must be enabled on a per-account basis.
Please review this entire guide before requesting CSS access. We do not grant CSS access to empty accounts. Instructions are located on the bottom of this page.
The CSS editor is available on:
The CSS editor lets you control how your pages look outside of what the built-in theme editor allows. Keep in mind we sometimes upgrade itch.io’s pages and it’s difficult to ensure those changes don’t conflict with your custom CSS. Enhancing existing components instead of trying to redo the entire page is the best way to avoid any problems.
The CSS classes and IDs listed on this page should be considered stable and you can use them for targets to your customization. Use any other CSS classes at your own risk, future updates to itch.io may not be compatible with your CSS. We'll do our best to be conservative about changes, but sometimes we have to make them. If we make major changes, we'll try to email all CSS users about the updates.
CSS generated by the itch.io theme editors is applied using CSS classes, so you can use ID selectors to have your style take higher precedence.
Custom CSS is a powerful tool, but can also degrade the quality of the page. Please keep the following things in mind when designing your page.
The content you provide for your pages (project, profile, jam, etc.) supports a
subset of HTML. If you'd like to target elements in your markup with custom CSS
you can give them a class. In order to prevent conflict with itch.io’s own CSS,
classes you use must begin with
custom-. Any other classes you provide will
be stripped by the sanitizer.
To access HTML mode in our rich text editor, you can click the
Once you start writing HTML with the rich text editor then we recommend only
editing as HTML, as the rich text editor may rewrite your markup and strip tags
you have added.
Please place all your custom rules inside of
#wrapper to avoid breaking or
altering itch.io core functionality.
Project pages that have embedded content (HTML5, Flash, etc.) have the same layout above, but with an additional element inserted above
If you need to reference external resources (images, fonts), you should make sure they're hosted into a reliable place with support for HTTPS. You can embed images and fonts directly in your CSS by Base64 encoding it.
If you would like CSS access on your account then please contact us.
Please tell us what kinds of changes you'd like to make to your page. We restrict access to the CSS editor by default because it makes it harder for us to upgrade game pages on itch.io without breaking custom layouts, additionally we expect you to use CSS responsibly.
