Here are some example page layouts you might be able to use. You can copy and modify these examples into your GC Articles collection to create page.
The examples are all responsive so they work on mobile and are generally accessible to a WCAG Level 2.0 AA level with user supplied images and alt text.
The content in the images is dummy content and is made to be replaced. When using images make sure you have the appropriate rights to use the image.
