Below is my client's website where we are trying to fix the margin and space limit on the right side of their website from the mobile point of view. His website is https://homemartessentials.com/ . If anyone has any insight on this, please let me know. I may also mention that I could not find a theme.css . The password is sitree .

Hello @letsgethelptyle ,

You can follow these steps: 
1. Go to Online Store->Theme->Edit code

2. Open your theme.liquid file, paste the below code before </body>

<style>
   @media (max-width: 768px ) {
       main#MainContent {
        overflow-x: hidden !important;
      }
   }
</style>

I hope the above is useful to you.

Kind & Best regards,
