Hello,
1) You can use Poedit or Loco Translate to translate strings but it’s for the 1 language only. You can’t create a multilanguage site using only these tools. That’s why to translate a mobile panel to another language you need to decide which multilanguage plugin you will use.
2) I have also added the below code to Custom CSS to align buttons because some products have the rating, other do not, some products have categories, other do not and it causes the different height of the product information
.content-product .product-details>.product-title {
margin-top: 24px
}
.content-product .product-details .products-page-cats + .product-title {
margin-top: 0
}
.content-product .product-title + .price {
margin-top: 25px
}
Regards
