Etsy shop

Hello, I have linked my Etsy shop to my website, it all works well, except that when using mobile phone to visit the page, the page (where my Etsy shop is) does not show completely towards the right. Only 2 and a half columns show. I have tried to modify Etsy plug in, but no luck.
Thank you very much for your time.
