Leuwi Hejo is a single post template for WordPress created with Divi Theme Builder. Thus, you can import it if you use Divi on your WordPress website. The template uses an uncommon design by not displaying the featured image. Instead, it uses a gradient background on the hero section. You can replace the colors of the gradient with your own colors. For your information, Divi comes with an advanced gradient builder to allow you to use multiple colors (more than two) on a gradient. Read this post to learn more.
You can also modify the hero section by adding background mask or pattern. Divi has a built-in feature to add a background mask and pattern.
