Did GitHub just change its default font family to system defaults?

Yes, the new font-family is now:<p><pre><code> -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;, &quot;Segoe UI Symbol&quot;;</code></pre>

I think, they did. I am running Ubuntu 14.04 LTS with Mozilla Firefox. The font size has a big size than the previous one.<p>Related discussion: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=12073109" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=12073109</a>

If you don&#x27;t like it, you can fix it by using this: <a href="https:&#x2F;&#x2F;github.com&#x2F;rreusser&#x2F;the-old-github-font" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rreusser&#x2F;the-old-github-font</a>

I incredibly hate this move by GitHub. I am using Chrome&#x27;s Styler extension to get back good old Helvetica. There should be an opt-out from this font stack at GitHub.<p>Screenshot: <a href="http:&#x2F;&#x2F;cloud.ahmda.ws&#x2F;UHjO9GC" rel="nofollow">http:&#x2F;&#x2F;cloud.ahmda.ws&#x2F;UHjO9GC</a>

Add this to &#x27;Stylish&#x27;<p>body, .intgrs-page .main-content, .blog-content, .migration-wrapper, .migrate-owners-wrapper, .setup-wrapper, .showcase-page-title, .tooltipped::after { font-family: Helvetica, arial, nimbussansl, liberationsans, freesans, clean, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;, &quot;Segoe UI Symbol&quot; !important; }<p>.markdown-body { font-family: &quot;Helvetica Neue&quot;, Helvetica, &quot;Segoe UI&quot;, Arial, freesans, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;, &quot;Segoe UI Symbol&quot; !important; }<p>body { font-size: 13px !important; line-height: 1.4 !important; }<p>.blob-code { line-height: 1.4 !important; }

Seems like it.<p><a href="https:&#x2F;&#x2F;twitter.com&#x2F;mdo&#x2F;status&#x2F;752561058011754496" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;mdo&#x2F;status&#x2F;752561058011754496</a>

Looks like it. I was thrown off too.

I wonder if they looked at the difference in markdown look on OSX+Chrome. Bold is completely broken, see screenshots comparison here (tweeted at Github): <a href="https:&#x2F;&#x2F;twitter.com&#x2F;MrOlovsson&#x2F;status&#x2F;752843094765236224" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;MrOlovsson&#x2F;status&#x2F;752843094765236224</a>

Noticed this earlier today. It&#x27;s using Ubuntu on Gnome Ubuntu 16.04 with Chrome.

Where is the blog post explaining how and why they did it?<p>I am really interested in the reasoning behind the change, the insights, I bet they are really interesting.

New font is awful

I like Segoe UI, so this works for me, at least.

Whatever it is, its legibility is horrible.

i think so, it used to be helvatica
