Jupiter X customizer allows you to have a highly customized blog and portfolio for your website which includes choosing a different layout.
To select a different layout for your single blog page:
1. From WordPress left menu, go to Jupiter X > Customize.
2. Choose Blog > Blog Single so that a new panel will open with the Blog Single options.
3. Choose your desired template, for example by choosing the second layout, you will have a full-width featured image and titles and other meta content positioned over the image.
4. Close the options panel and Publish the settings.
Note: Templates are only available for Blog Single post type and Portfolio Single doesn't have such layouts. Because Portfolios posts can be created with Elementor and don't require prebuilt templates.
