Change Color of Homepage Content Area

Hi! Can someone please help in advising me on how to change the color of the Home page content area? I have search the internet and found some articles on using css, but I have very little coding experience. I also tried to paste some css coding in the wp editor, to no avail. Any help would be greatly appreciated. Thank you.

Hey there

I hope you are well today.

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.
Admin Area -> Appearance -> Customize -> Additional CSS

/color content color/
.newspaper-x-blog-post-layout-b {
background: black;
}

You can send screenshots indicating the parts you want to change from the demo site.
Or from your website with an included URL to the site.

Best Regards,
