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.

please help:
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail

I can't use it then.

Thanks for your review. We faced an error with our server for a few minutes and this made our app unavailable. We have managed to fix this problem and everything is back to normal now!
We are really sorry for any inconvenience this may have caused.
It would be great if you could reconsider the review you just left as long we fixed the error fixed immediately and everything is working fine now.

This application is amazing.
However, it can not be changed according to the theme.
Evaluation is a 4 star.


I specially came here to write a review for this fantastic app. Despite I started with a very basic theme, I've been able to develop an outstanding looking website just because of this addon. I've previously worked on Wordpress but none of the external CSS addons in Wordpress has ever been so effective. Every code that I put into this definitely works. For all the other apps I have to switch between a couple of options to get to the best app but for custom CSS I have never needed an app other than this. This app is worth hundreds of dollars!!!!!!!!!!
