Hello,
2. I would recommend you to use a graphics editor and prepare all images (make them the same size) before uploading it to your media gallery, then your grid will look much better.
Also, try this code:
.categories-mask {
bottom: -50px;
}
.categories-mask span {
display: none;
}
.category-grid.product-category.product {
height: 180px;
margin-bottom: 50px;
}
4. Unfortunately, for header type, you selected, there is no possibility to use “Form on hover” type. To replace the search, you need to edit etheme.js and header-structure-4.php files + write custom css code. If you need help with additional customization you can contact WPKraken team.
