How to change the background colour on this theme

If you’re not using a Child Theme, and if the theme doesn’t have a designated section of the dashboard for CSS modifications then install this Custom CSS Manager plugin https://www.ads-software.com/plugins/custom-css-manager-plugin

Then use its “CSS Code” section of the dashboard to hold your CSS modifications:

Alternatively use your Child Theme style.css file to hold your CSS modifications:

#wrap {
    background: pink
}

Thanks Andrew for the prompt reply – will try those options now.

Have a good weekend.

Andrew- I edited the CSS code – piece of cake and thanks again..
