Display the <H1> only on mobile on collections (Palo Alto Theme)

Hello guys,

For UX reasons, I would like to display only the

without the background image and the text on mobile, but I would like to let them visible on desktop.

I tried this custom CSS :

@media screen and (max-width: 749px){.collection__description{ display: none; }
@media (max-width: 749px) {.banner-img {background-image: none!important; }}
@media (max-width: 749px) {.three-fifty-height{height: 50px}}

It works but the

is taking a lot of space because of this html line

style="min-height: calc(216px + var(--header-height))

on the element. And I don’t know how to change that.

Can someone help me please ? (I can’t share the url as the website is not open yet)

Many thanks
