Hi @gzagza
You could try these in your _theme.less override file.
@media all and (min-width: 780px), print {
.abs-product-options-list-desktop dt,
.block-giftregistry-shared .item-options dt {
clear: left;
float: left;
margin: 0 10px 5px 0;
}
@media only screen and (max-width: 780px)
.navigation .level0 > .level-top {
font-weight: 700;
padding: 8px 40px 8px 15px;
text-transform: uppercase;
word-wrap: break-word;
}
There may be a few more that you need to tweak but this seems to work for the default Luma theme.
All this has done is:
1. changed the minimum width of the product page (was originally 768px)
2. Changed the maximum width of the "burger burger" menu will show (Again originally 768px)
Hope it works for you and helps 🙂
