10 June: New customization styles, email improvements, dark mode cover images and more
You can now add circular buttons, choose flatter design elements, and select cover images specifically for light and dark mode in GitBook
✨ New and noteworthy
New depth and circular corner styles in site customization
We’ve added two new style options to customization settings for your docs site.
Firstly, we’ve added a new Depth style setting in the Site styles panel, which lets you choose from two depth options. ‘Subtle’ is the default style, and adds some shadows and elevation to UI elements like buttons. The new ‘Flat’ style removes all shadows and elevation for a clean, simple look.
We’ve also added a third corner style in the same panel. Along with our existing ‘Straight’ and ‘Rounded’ options, you can now also choose ‘Circular’. This will affect UI elements such as buttons, TOC highlights, site sections and more.

Cover images get dark mode support
Your page cover images no longer have to work for both light and dark mode simultaneously. Now, when you add a cover image to a page, you can also upload a dedicated version of the image to display when your docs are viewed in dark mode.
To do this, simply hover over the cover image in the editor and open the Options menu . Here you can choose Replace image and select a new image for light or dark mode.

New notification email design
We’ve improved the design and information included in the notification emails you receive when someone comments on a space or a change request your own.
The new design includes the name of the change request or space, and the page, instantly giving you more context without needing to click through and read more.

We plan to roll out similar improvements to our other notification emails soon — stay tuned for more news on that!
We’re constantly working to improve the way you and your team work in GitBook, and value your input on features, bugs, and more. Make sure you head to our official GitBook community to join the discussion.
