Change order of Product Items in mobile view

Im having problems changing the order of the stack of ProductItems when in mobile resolution. I need to have the following order (from top to bottom) :

Product title> Gallery > Description > Variant selector > Add to cart button. 

I tried to make a custom flexbox but to no avail. Id appreciate the help. Thanks!

I managed to get results with the following, which works for me,  but the title still wont come at top.

@media screen and (max-width:640px) {
section.ProductItem-summary.clear {
    display: flex;
    flex-direction: column;
}
figure.ProductItem-gallery {
    order: 0;
}

.collection-type-products .ProductItem-details .ProductItem-details-excerpt {
    order: 2;
}
.collection-type-products .ProductItem-details h1.ProductItem-details-title{order:1;}
}

Ive put order 1 in title here because putting it down as 0 doesnt work. And even starting the order from 1 among these doesnt work either sigh

hope this may help someone
