git-wiki-theme VS reverie

I believe it is a bug affecting IOS devices in Git-Wiki. https://github.com/Drassil/git-wiki-theme

You could build a wiki yourself / add on to an existing wiki with those features as other's said & host it on GitHub pages. And use something to render your Markdown content, you maybe want to check this out Markdown-Tag: Add Markdown to any HTML using a tag & if you prefer not to build something from scratch may I suggest using this git-wiki-theme: A revolutionary full-featured wiki for github pages and jekyll. You don't need to compile it! hope this helps somewhat.

I've customized this theme to suit my taste: https://github.com/amitmerchant1990/reverie

If you like writing in markdown, you can use GitHub Pages for free and it's easy to put it under your own domain or later rehost on another server. There are a bunch of templates. I use reverie.

If you dont want to spend too much and its just a blog you need maybe you can find one of those "create a blog sites" that would suit you best and host it on your own domain. Like this one: https://www.blogger.com/, I personally use https://github.com/amitmerchant1990/reverie but its a bit technical to set it up and write articles for it.

You can do it pretty easy on github pages! I think it was as easy as forking a template, changing _config.yml, replacing their _posts with your reddit post's markdown, and adding a header to your markdown (for tags, page title).
