Thanks for the example image this really helps :)
The image height is defined by its container row, so we would need to force it, which could be achieved in a few ways.
( maybe i am overthinking this but... )
Firstly we should give it a custom ID or Class to target it with CSS better - we can right click on an Image Element:
Then in Lay Options - Custom CSS & HTML -
we could force the image to have a certain height e.g:
This could be also set to % or VH (viewport height)
Less advisable, but maybe it suits you, would be to change its position property: https://www.w3schools.com/css/css_positioning.asp
Fixed - would position the image relative to the viewport
Absolute - would position relative to the nearest ancestor
Good luck and let me know your thoughts
Happy new year and thank you for using Lay Theme!
