Hi Vortana-
Thanks for reaching out, and for your interest in BoldGrid’s WordPress Themes.
You can definitely achieve this without too much extra customization. I think the main thing to keep in mind is the difference between the Theme itself, and the sample content that it comes loaded with.
For example, if you check out the General category, there are a couple of good options using Crio at the top:
Once you install the theme, you don’t need to use the fancy block designs that are in the Inspiration content, you can simply write your content and you’ll have a good distraction-free appearance.
Some extra tips:
Medium uses a narrow “container” for the page content, so make sure to set up a container for your posts and pages in the Customize > Design > Blog > Posts > Container section and the Customize > Design > Pages > Container section.
Make sure to remove any distracting sidebars, in the Customize > Design > (Blog Posts / Pages) > Sidebar menus.
