Flatiron - Is full-width image block possible?

Site URL: https://www.jaimiholker.com

Hi Folks,

I've created a website using Flatiron.

The homepage has an image block which I would like to use the full-width of the site.

Is there a way to make this image block full-width?

Thanks!

Add to Home > Design > Custom CSS

.homepage section#container {
    max-width: 100%;
}
