The option "Dashboard look & feel" allows you to chose a dashboard type. There are two layouts available.
There's only one section. The content is centered. You can fully customize the content.
Default Confluence dashboard
The dashboard is divided into two sections. The left section has a predefined Confluence panel, enhanced with new functions. You can fully customize the content of the right section. You can also define the width of the right section.
You can style your dashboard even further. Here are the available options.
Dashboard background color
Input a hex value or use the built-in color picker to set a background color for your dashboard.
The background color is not visible when a background image is set.
Upload a background image for your dashboard. This setting overrides the background color. The image will be automatically centered and resized.
How to change the background image:
Delete the existing background image.
Upload a new image.
Enable the Tile Layout checkbox to give every macro a white background.
This is a very useful feature because some macros have a transparent background. Also, Tile layout adds some white background around the macros. This way, headings and texts around those macros also receive a background.
Enable the Dashboard buttons checkbox to hide the "Create Space" and "Invite User" buttons on your dashboard.
Configure the content on your dashboard
To configure the dashboard's content, you need to be an administrator and edit the Default Welcome Message template.
You will find this template in Confluence administration > Configuration > Global Templates and Blueprints > System templates > Default Welcome Message.
Click on Edit. You can now create a dashboard template.
