Banner size for Mac devices

[Daniel19901]

Hi,

Can anyone help me understand what should be the right size for a banner, so that it will be a full screen also for Mac?
My first homepage banner is fine on other devices, but on Mac you can see the section bellow, which doesn't look good. Is there a size that I can use that will suite both ?

Hi @Daniel19901 

You can add this code to Custom CSS section of that banner in Online store > Themes > Customize to check

.banner--adapt {
height: calc(100vh - 38px);
}
