Can't stretch section (side to side)

hi! I’m building my first website on webflow.

I have these vertical black lines on the sides which are the body background color. I needed to stretch the white section from side to side. can anyone help me with this? Thanks in advance!

the URL:

Here is my site Read-Only: LINK
(how to share your site Read-Only link)

Looks like a container but if you can share the read only link I’ll take a look! (It’s not the same as the link that you have shared, but you can find it next to the publish button on your site)

Hey David, thank you for your reply!
Here’s the link:

Is the lottie animation meant to stretch the full width of the site? It’s got a max width of 1600px right now

it’s, I wanted the Lottie to stretch.
yes, max-width was 1600px but my screen is 1440px and it still doesn’t stretch.
I deleted the max-width and am still getting the same result.

here is a screen record of the issue:

I would really appreciate if someone could give me a hand on this
