Deep linking with fragmentions
When I was marking up Resilient Web Design I wanted to make sure that people could link to individual sections within a chapter. So I added IDs to all the headings. There’s no UI to expose that though—like the hover pattern that some sites use to show that something is linkable—so unless you know the IDs are there, there’s no way of getting at them other than “view source.”
But if you’re reading a passage in Resilient Web Design and you highlight some text, you’ll notice that the URL updates to include that text after a hash symbol. If that updated URL gets shared, then anyone following it should be sent straight to that string of text within the page. That’s fragmentions in action:
Fragmentions find the first matching word or phrase in a document and focus its closest surrounding element. The match is determined by the case-sensitive string following the # (or ## double-hash)
It’s a similar idea to Eric and Simon’s proposal to use CSS selectors as fragment identifiers, but using plain text instead. You can find out more about the genesis of fragmentions from Kevin. I’m using Jonathon Neal’s script with some handy updates from Matthew.
The fragmention functionality is ticking along nicely with one problem…
I’ve tweaked the typography of Resilient Web Design to within an inch of its life, including a crude but effective technique to avoid widowed words at the end of a paragraph. The last two words of every paragraph are separated by a UTF-8 no-break space character instead of a regular space.
That solves the widowed words problem, but it confuses the fragmention script. Any selected text that includes the last two words of a paragraph fails to match. I’ve tried tweaking the script, but I’m stumped. If you fancy having a go, please have at it.
