I created this public app for people to submit styles of elements, free for the Bubble community to use. The idea of this app is similar to the Forum App, but focused entirely on the design/style of elements in Bubble. If you have styled certain elements and would like to share the design/formatting, you can create a new page in this app with your design. Once you’ve finished your page, you can go to the the ‘submit_your_style’ page, so that your style is included in the homepage repeating group.
*Edit: In order to use the Styles in this app, you can navigate to the Styles tab, right-click on a Style, select ‘Copy Style’ and paste the Style into your Bubble app’s Style list. Hope this helps!
