Figured it out. I needed to change the Entry Header not Featured Image Header. Was just referencing the wrong class.
body.page-template-page-services-php .entry-header,
body.page-template-page-team-php .entry-header {
background: #fff !important;
Do I need to add anything else to this if I’m placing it in Simple Custom CSS? I also edited the blog headers in that area, which seemed to work fine. Thanks again!
Thanks for the reply. I pasted the above code into Simple Custom CSS, but it did not change the header on either page. I double-checked to be sure the pages are designated to the page-services and page-team templates.
