Site width setting in Alchem theme.

Hello,

This is my first time making a website and things are going pretty smoothly except for a couple of things.

1. My blog content goes beyond the width of the page.
2. It seems like the width of the content part of each page is not full width, but I already set it to be full width.

My website is mrsenglish.net. I am using Alchem theme.

Thank you in advance for your help!
