Dear gewoonbovenaan,
Thank you for your inquiry.
1) You added custom CSS – it will work (https://prnt.sc/PeHqH7W25Nwh). However, if there are widgets on the page, it will break the page layout (https://prnt.sc/c-74uXdywRFW). Therefore, it is better to use this code:
.archive .content-page{
padding-top: 50px !important;
}
We have added it for you.
2-3) You need to move all the widgets from the Main Sidebar to the Shop Sidebar (from https://prnt.sc/w95va8ZqbJuV to https://prnt.sc/JJWSWYDtpP1b). We have done this for you.
4) Unfortunately, this can only be done through customization in a child theme. Please provide FTP access for it.
5) To change the margins, you need to use Computed Box (https://gyazo.com/0010bca7eece79a2d352266ab24157b8). Currently, we have set the top margin value to 25. If desired, you can change it to any value (https://prnt.sc/8rOhxuFmZsN1).
6) Please provide a screenshot.
7) Fixed. Currently, the only way to align the buttons without additional customization is the option: WooCommerce (Shop)->Shop->Products style->Product Title Limit By.
We hope this information is helpful.
Best Regards,
8Theme’s Team
