Easily customise your Shop look and feel

CSS Hero is a simple point-and-click application to fully customize your Shop's appearance, enabling the user to easily add CSS to Shopify sites.

It comes with both a friendly WYSIWYG live editing interface, delivering a no-code experience, and with a powerful code editor, for those willing to get their hands deeper in CSS. In both modes it provides an immediate preview of the edits on desktop and on any screen resolution.

A light footprint

Upon saving CSS Hero will take care of displaying your edits on your Shop in the less obtrusive possible way. It will only include a static .css file and a .js file (only if you provide js edits). Both files are hosted on Shopify as part of your assets and will be directly referenced in your theme files.

Save directly on your shop or export code

CSS Hero has no vendor lock-in, once you're done with editing you can either choose to save and let the app display your edits on your shop or export it and use it as you prefer.
