Wexley - Can't reduce page padding beyond 20px

Site URL: http://www.joinerarchitecture.design

Hello! I can't seem to reduce the page padding on my site to go below 20px.

When you visit my site, you will see a 20px padding on the left and right sides. I want the content to bleed to the very edge of the browser window.

I've tried:

#page {
    width: 100% !important;
    margin: auto !important;
    padding: 0px !important;
  }

Anyone have an idea what to use? Thanks!

div#canvas {
    padding: 5px;
}
