Dividers - new Google Sites
Visually break up the page with horizontal dividers
On the Insert panel on the right look for the Components section
Use the Divider option.
A horizontal line will appear as it's on section in the content.
Move the divider to the correct place on the page
The divider always takes the background colour of the section immediately above it.
If the section above uses a custom background image the divider will take the Style 1 background colour.
A divider immediately below the page header uses white as its background colour.
You cannot change the background colour of the divider.
You can change the colour of the divider if you add a Custom Theme
