@Maha It’s not in the website anymore. However, that site is inside Onsen UI repo so you can serve it locally in your computer: https://github.com/OnsenUI/OnsenUI/tree/1.3.19/css-components
I think gulp serve should be enough.
@munsterlander I think we haven’t update it recently so it must have been there for a while
We still need to give some love to the Theme Roller but we must focus on other things right now.
@munsterlander It’s a good suggestion but right now we are way too busy with other stuff. I hope we can get back to this at some point
