Hello,
Sorry to say but that design and style for Variation doesn’t come directly from Theme end. It might be achieved through some third party Plugin.
Although, there are some predefined Custom Layouts for the Products available under the Dashboard > Layouts > which you can make use of for the Single Product pages. Like here is one of the example from the latest Mega Electronics Demo: https://woodmart.xtemos.com/mega-electronics/product/apple-macbook-pro-16-m1-pro-2/
You can read more about the Theme’s Layout Builder here:
https://xtemos.com/docs-topic/single-product-page-builder/
https://xtemos.com/docs-topic/woodmart-woocommerce-layout-builder/
Regarding the Cart Strap that you are referring to, is the Sticky Add to Cart which can be enabled for the Single Product page under the Dashboard > Theme Settings > Single Product > Add to cart > there you can enable the Sticky add to cart: https://snipboard.io/KervLF.jpg
It previews like this on the Single Product page: https://woodmart.xtemos.com/theme-settings-tooltips/sticky-add-to-cart.gif
Further, if you apply the following Custom CSS on your Site under the Dashboard >> Theme Settings >> Custom CSS >> Global CSS section:
.wd-sticky-btn {
transform: none !important;
}
This will make the Sticky Add to Cart to stick to the strap always like you referenced.
Hope this helps !
Best Regards.
