I found a way but it’s a pain in the *** to set up:
- add a layout to a page
- add another layout into the 1st layout
- add a block to the 2nd layout
- try to select the 1st layout (this is the first pain)
- edit the 1st layout design and set its template to Paralax, change its background to either image or color, save it
- if you want to change anything in the 1st layout after saving it - good luck selecting it
But if you manage the above, it actually makes a screen wide strip with a block contained within the Main area. If you want the block to be full screen as well, then don’t add the 2nd layout and disable the 1st layout grid container.
I thought there would be an easier way of setting up screen wide strips.
