Love this stylesheet! Thanks for doing this.

Noticed this url isn't working though.

Awesome stylesheet! Using this in my Chrome extension.

@tuzz This looks good. Are you the original author, and is there a particular license on the stylesheet?

Awesome stylesheet.

Big thanks! I hope you won't mind me using your stylesheet in vim-preview plugin: https://github.com/greyblake/vim-preview

Do you have a license?

For an up-to-date stylesheet, see https://github.com/sindresorhus/github-markdown-css

How do you make a css stylesheet for html on github and github windows using Sublime Text

do you some other darkness style scheme?

table {border-collapse:collapse;} look beterr

Hi everyone, sorry I didn't realise this had become (somewhat) popular.

This stylesheet is based on GitHub's styles circa mid-2012.

It's not a copy, but was heavily inspired by theirs and closely replicates their visual design.

You're welcome to use it under the MIT license which I have included in the gist.

I don't plan to maintain this. There are plenty of great forks you should check out.

@jiangkunhe Thank you

In order to remove the small, interstitial spaces between cells, add the following to your css:

table {
  padding: 0;
  border-collapse:collapse;
}

After:

Can anyone explain me how this style works on github. Or even if it works at all. I'm finding answers that says that css styling like this can not be done on github, see this.
Personally, I've tried it several times already, never being able to do such a thing, but I'd love to.

Awesome!

@tuzz: Is there any possible way to implement these stylesheets into README.md markdown so it shows on GitHub? Just including the .css in <link href> in the markdown doesn't seem to work on GitHub.

@davincif what are you trying to do? The purpose of this is to emulate the CSS used within the markdown viewer and wiki pages. It's meant to be used elsewhere.

@tuzz that's not how it works. If you want to change how you see github readmes, you can add an adjusted version of this to a browser plugin like Stylebot. If you're trying to change how everyone sees your readme, you're out of luck. You may be able to edit inline styling, but that's probably it. Read the Markdown documentation and Github's Markdown documentation for more on what's allowed within markdown.

This is the original css that uses Github https://primer.style/css/getting-started
😄

This scrolls pres horizontally bad for me, the code overlaps and sticks out the edge of the pre and the pre moves inside of the div, not the code inside of the pre

@tuzz Thanks for publishing this:
I've reused your style sheet in a Windows batch script that converts a Markdown file to HTML, and displays it in a Web browser.
The batch is described here: https://www.dostips.com/forum/viewtopic.php?f=3&t=9372
And it is available there: https://github.com/JFLarvoire/SysToolsLib/blob/master/Batch/md2h.bat

For just wanting something that looks good enough to not have someone bother you about it, this plus Markdown is perfect.

I am glad to announce that this style sheet is used in my tiny humble project at https://github.com/ildar-shaimordanov/git-markdown-html.

Thanks!

I wish I was as skilled in CSS 😂
