Update readme.md

Add CSS to prevent text overflow.

Normally, this style should be inherited from ancestor elements(In github-markdown-css, this style is set in .markdown-body.). However, if no ancestor element has set this style, it's better to set it here.

Hmm, I don’t think that’s a good idea. There are tons of things that could be done to make typography better. This seems like a slippery slope. If we’re going to include things from .markdown-body here, why not font-size, -webkit-text-size-adjust, color?

This section already links to that project for when folks want the exact same CSS as GH. The CSS included here is more to make footnotes work?

Alright, we should indeed only include the minimal necessary styles.

Hi team! Could you describe why this has been marked as external?

Thanks,
