Vertically Center a Section on one Page

Hi there,

I want to vertically center the only section on a single page on our client's site.

https://www.rbjl.com/

Particularly on mobile, it seems hard to center!!

Would appreciate any help!

Thanks,
Adam

Add this to Design > Custom CSS

/* Vertical center section on Mobile */
@media screen and (max-width:991px) {
body.homepage article section {
    position: fixed;
    top: 50%;
    transform: translateY(-50%);
}
}

Thank you Tuanphan!!
