The beauty of Mobirise is that you simply drag-and-drop blocks onto your pages. That simplicity is what most users appreciate so much: you can create beautiful websites without having to know how to code.
But if you want something slightly different or you're looking for blocks that simply don't exist in the Mobirise themes, in most cases you'll have to use the Code Editor to get what you're after. Obviously anything is possible if you go that road, but if you're not too comfortable with coding, there has to be something easier, don't you agree?
This is the main reason why I created the Design Blocks extension, accompanied with the Design Blocks Gallery. Designers can create fantastic blocks and upload them to the Design Blocks Gallery. Mobirise users can simply open up the Gallery from inside Mobirise and import any block they like.
Both AMP and Bootstrap 4 are supported by the Design Blocks extension. Keep in mind that Bootstrap 3 *might* work, but most likely won't or won't work entirely.
Design Blocks are very similar to User Blocks. If you've created a User Block inside Mobirise, you can upload that as well. A User Block is named "userblock.js".
Are you a designer and want to create Design Blocks for others? Here's how it works.
