Hi @laproductora I have ben checking your code and there are some CSS settings that should be dane to make your site to work as you wish. One thing that I have found is that collection list wrapper in block 65 has position absolute that cause overflow because as you probably know when element is in absolute position is removed from standard flow.
You can start there to fix some odd behaviour. I can see that you have set grid (block 65), when you need stack elements in standard flow (top-bottom) there is several ways to do that. You can set on mobile device grid to col1fr/auto ( that remind me that you have several manually set auto rows).
Please check this post to understand what I mean. You can wrap elements in block etc. There is a more issues that can be fixed.
You can show element only on certain devices in this section
you can get more informations in Webflow university in section hide elements
Hope this will give you some idea where to look and what to improve or change.
