I am editing the 'Bizz' portfolio Wordpress theme(http://www.wpexplorer.com/bizz-wordpress-theme). It includes custom post types for managing portfolio examples, the highlights on the homepage, etc.
I want to style the background color displayed behind each 'highlights' heading with a different color, but since they're served dynamically, I'm not sure how I should target each h2.
Would it be best to attach a unique class to each of the three headings through the php, or try to target them through CSS selectors? And how would I best do that?
My major concern in using CSS selectors would be backward compatibility, I dont know that I want to bulk up the page with extra bootstraps.
How should I go about it? Thanks!
