Use text for source & example links.

I feel this is both more self-evident and easier to maintain.

Yes!

I would just change to singular [Example], even when there are several:

• it's nicer to the eye, especially next to singular [Source]
• sometimes there is just one
• users will be looking for an example (ie how do I use this function? rather than what could I do with this?, which is more the role of the gallery and the general collection)

I’m okay capitalizing, but I think examples plural is appropriate because in the common case there will be more than one example.

[Fil]

Sorry I did not mean to capitalize, it was a slip of the keyboard. But come to think of it it looks good :)

My only concern is that this [Source] [Examples] part is now more visible than the function's name. Maybe <small> like in the first line of the simulation below?

Also, why the rel-nofollow?

(PS: don't bother applying whichever style to the whole file, at the end of this process I'll clean up and push a single commit.)

[mbostock]

GitHub sanitizes the styles, so <small> doesn’t work, sadly. (See test.)

Made a few more typographic adjustments, but the design space is pretty limited by GitHub here.
