Devlin: How to remove footer?

Can anybody tell me how to remove or hide the entire footer in the Devlin template? I am not really experienced in CSS, but I did a search found this code, but it did not work. Maybe I formatted it wrong?

footer-nav { display:none; }

I figured it out. Here is what I did for anybody else with the same problem:

Go to the page in your layout editor. Select "page settings" in the top right and go to "advanced". Inject the following code into your page header:

<style>
#footer {
 display: none !important;
}
</style>

This just removes the content from the footer, for me. Not the bar... I'm using Marquee, do you know what the issue could be?

You can also go to Design -> Style Editor -> Site Footer -> Hide

I'm using flatiron. but it not work both.Do you know what the issue could be?
