You'd have posts with different tags such as Minimal, or Design. Monopiny supports an in-app tag page – you'd see them in /tag/minimal or /tag/design, but can a page have multiple tagged posts? Yes! That's what a tag page is for.
Tag your posts first.
Notice that your tag page deem mIniMaL, Minimal, minimal, MInImaL as minimal. A tag page catches all these posts no matter how much it's weirdly formatted.
Creating a tag page.
Create your tag page on your custom page editor.
You can type as many tags as you want, but it won't show any duplicate posts - your post can have multiple tags, but it won't show your post multiple times.
