Wells background image for homepage

Site URL: https://crossingtheline.squarespace.com/

Hello,

Hoping to get some help adding a background image to the homepage of my site, using Wells theme.

Using custom CSS I want to add a background image that covers the blog and right sidebar, but leave the left sidebar navigation clean.

I tried this but haven't had any luck:

div#canvas {
    background-image: url(https://i.pinimg.com/564x/ca/71/f6/ca71f61e01e93adcca2683696296e787.jpg);
    background-repeat: no-repeat;
    background-size: cover;
}

Thanks in advance!

Carly
