My Boss Wants To Remove The Background Completely And Stretch The Site to Full Size, Is This Doable?

But...I still have a thin line outlining the page. Is it possible to remove this?

Here's the site I'm working on:

Thank you so much,

Hello,

Paste the code given below in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.container {
box-shadow: none ! important;
}

This will solve your issue.

 

Worked - thank you Piyush!
