A general suggestion for programming blogs: instead of Medium, try using something like Hexo[1] or Hugo[2] and deploy for free on Github Pages or Netlify. Publishing content is as easy as `hexo deploy` or `git push origin master`.
You get complete control with a static site generator and can remove things like the sharing bar and animation. There is almost no maintenance required, because the site will be a collection of static HTML files.
