Recent Blog posts on homepage with different colour background
I am starting to find my feet with the HTML blocks to customize aspects of my site. I want to create a recent blog posts section on my homepage with three photos each linking to a different blog post. Ideally each would have the title of the blog post under it. Most importantly, I want to learn how to add a splash of colour in the background of a content block. This is not my website, but it gives an idea of what I am hoping to recreate: https://laurafenny.com/
The bar of brown under the photo of herself with three photos as links.
Any ideas? Is Smugmug too limiting? Here is my website for reference: https://www.jbriginshawphotography.com/
