Hi there,
Peak uses the Header Element:
https://docs.generatepress.com/article/header-element-overview/
Header Elements can dynamically display content such as the Post Title or a featured image as a background. Except on certain special ‘pages’ like the Blog. In order to change these you will need to:
1. Edit the existing Header Element assigned across the site and in the Display Rules tab remove/exclude the Blog
.
2. Now create a new Header Element using the exact same setup with two differences:
a. the Header Element will be plain HTML eg. <h1>Content</h1>
b. the Display Rules will only include Blog
