Theme Horse

Hi

No, the Theme is totally responsive but for some elements and components like external embed links and tables, you have to set the width of the wrap with the specific class
We are using the popular framework ‘Bootstrap’ and it even has documented to wrap with a specific class. You can view the documentation/instruction here
But If you use the Block feature of WordPress then you don’t have to wrap or set the width. You can directly added embed videos and tables.

Thanks
