About Custom Css

Flowzy proudly presents its first APP for Shopify platform which is also totally free!

Sometimes you may find yourself needing to add custom CSS to your Shopify website without editing theme's source files. You just want to open an editor and start writing CSS code to hide elements, change fonts and colors or style a particular page. This is the APP you have been looking for! Installation requires just a few seconds and there is nothing to configure. Just open Custom Css and bring your ideas to life!!!

Our tool allows store administrators with knowledge of CSS to override theme default styles and apply their own code to the website. There is no need of editing any files of your theme, avoiding the danger of breaking your website.

We offer a modern and user friendly code editor with syntax highlighting on the fly, code folding, matching parentheses highlighting and cut, copy, and paste functionality.


If you want to uninstall our app for any reason (we hope you will not do that!) and also take out the CSS code you have written already through our app, you have to remove it before you uninstall the app.

We're really glad to hear that you found our app useful! Thanks for supporting us :)

If you're a CSS developer who builds shopify stores, and you need design flexibility outside of the range of your customize theme GUI, this app is for you. Just like its name, it allows you to add custom CSS, simply and perfectly.
