Hi Jens,
Right now, there’s no built-in option in the Site Editor to control how block looks on mobile.
However, we can work around this by creating two hero sections—one for desktop and one for mobile—and using a bit of custom CSS to show/hide them depending on screen size.
What to do
- Duplicate your hero section so you have two versions:
- Give the desktop one the class: hero-desktop (Block → Advanced → Additional CSS class)
- Give the mobile one the class: hero-mobile (Block → Advanced → Additional CSS class)
- Adjust the mobile version so it’s cropped and styled how you want it to look on smaller screens.
- Add this CSS (Appearance → Editor → Styles → Additional CSS.
/* Mobile-first: show mobile hero, hide desktop hero */
.hero-desktop { display: none; }
.hero-mobile { display: block; }
/* Switch at tablet/desktop sizes */
@media (min-width: 781px) {
.hero-desktop { display: block; }
.hero-mobile { display: none; }
}
That’s it—on phones you’ll see the mobile-optimized hero header.
