Step-by-step instructions
- 01
Find your way around the editor
The editor has Save at the top and Undo, Redo, Desktop, Mobile and Preview in its toolbar. The right side provides Content, Blocks, Body, Images and Uploads, rather than the older Padding / Style / Content tabs.

Drag in a content module
Choose modules such as Heading, Paragraph, Image and Button under Content and drag them into the central canvas. Start with a simple structure, then add copy, images and action buttons.
- 03
Edit text and links
Select an inserted module. Paragraph offers font, bold, lists and Insert/Edit Link in its text toolbar, with Font Size, Color, Text Align, Line Height and Links on the right.

Preview different devices
Select Preview to switch between Desktop, Tablet and Mobile and inspect dark mode. Use Exit Preview to return. Check images, buttons and linked text for overflow.
