Today we are excited to introduce Responsive Content and Hover Content to Divi, including native SRCSET support for responsive images. This update allows you to serve different content to visitors based on which device they are using to browse your website, giving you even more fine tuned control over your responsive designs. Responsive editing is now available for all Divi module content settings. This feature also brings Hover Editing to all Divi content options, allowing you to swap images, videos and text and more on hover. Combined with Hover Editing for design, you can now create even more dynamic and meaningful hover effects.
