Hello,
Concerning reviews tab refer to this article:
http://masterns-studio.com/blog/woocommerce-enable-reviews-products/
For search form use this code in custom.css file:
.woocommerce-product-search label.screen-reader-text {
display: none;
}
.woocommerce-product-search input[type="search"] {
height: 35px;
width: 150px;
margin-top: 20px;
}
How to create custom.css you can watch in this tutorial (it’s for Legenda theme but the process is the same).
Regards,
Eva Kemp.
