How do I change the background/text colour of the author / date / category?

Hi there,

try adding this CSS:

.single .page-hero H1 + p {
    display: inline-block;
    padding: 5px 10px;
    background-color: #fff;
}

When I first saw that GP had an annual fee I was pretty annoyed. Didn't feel like it was something I should be paying multiple times for, kind of thing, y'know? It's been about 1.5 years now and I've come to feel that the annual fee is very much worth paying for, for updates and the customer service. I'd be so lost without you guys.

Yes it worked, thank you muchly!

You're welcome - and thanks for the great feedback, glad to hear that !
