Netlify CMS mobile responsive CSS

So far I’ve been waiting so long for the Netlify CMS to be working on mobile devices so I wrote my own piece of CSS as below. Add it to your Netlify /admin/index.html file and below the closing </body> tag so it can overwrite the netlify-generated css.

Screenshots for your reference:

As note by Chris in the comment, should you need to update the CSS classname, please follow his instruction.
