Change background color for sections

Hi,

I'd like to change the color of the sections on my home page. I know how to import a 1500 x 2500 colored rectangle into the section but it doesn't cover the entire section. Any advice?

Thanks

@ozzyfan123 Which section?

I have 5 sections on the home page: The Problem, the solution, services, testimonial, and opt-in. I'm trying to re-create the sections as jpegs but can't figure out how to make it so the background color goes from left to right completely without a border. Ugh I hate Squarespace.

add to Home > Design > Custom CSS

div#new-page-3 {
    background: red;
}

you want like this?

I don't know what that is - but thanks for getting back to me. I don't want to do coding - maybe I should go back to Wordpress. Thanks!

Not many WP themes will support that. You can use Page Builder in WordPress, you can change everything. eg: Elementor, Beaver Builder

I love Beaver Builder.

Thanks!
