All of our WordPress themes allow setting a custom background for page breadcrumb from the theme options panel. However, if you want to set a custom breadcrumb background for a particular page, then the theme also gives you the option to do that. For example purposes, we will use our Sharai Khana WordPress theme. You can follow and use the exact instructions for our other WordPress themes.
Here go the step-by-step instructions.
Step 01: Go to the WordPress admin panel.
Step 02: Navigate to Pages>>Add/Edit any page.
Step 03: Next, you will get the Featured Image option right side of the page.
Step 04: Add the image and click the Publish/Update button.
Step 05: Refresh the front-end page, and you will get the result.
I hope that helps.
