Right Side Gap Error on Mobile?

Hey everyone, when viewing my website on Chrome using my iPhone 14 Pro (if that matters) I get a strange white gap on the right side of my website. I don't have any custom CSS set up and have been struggling to find a solution that works. If any one could help that would be great! Thanks

My website is www.artallaglow.com

Try adding this to Design > Custom CSS then check again

@media screen and (max-width:767px) {
a#site-title {
    font-size: 20px;
}
}
