How to remove div class="woocommerce"?

Question

WordPress

Good evening .
I'll go straight to the point.
I want to push the footer to the bottom of the site using flex. And I managed to do it. However, on the Cart page, checkout, content-none (this is if nothing was found in the search), etc. wrong location of the blocks, and everything is different everywhere (somewhere the footer began to enter the "site-content" block, somewhere to go beyond the area of ​​​​the general container (to which I prescribed flex)

Please tell me how can I fix this, or where should I look.
The theme is self-written.

Answer 1

The issue was resolved, when I wrote the code in functions.php instead of add_action I wrote remove_action

Answer 2

You need to look in the Woocommerce template of your self-written theme, if there is none (and it most likely is not), write. There are a lot of materials on the net about how to adapt the theme for the woocommerce plugin.
