Use tabular numerals for phone numbers?

[kennethormandy]

I realised it would be possible to use different numeral sets for phone numbers (and possibly other things) in certain context. For example, in a paragraph you might want a phone number with old-style numerals:

But in most other situations you’d probably prefer tabular numerals:

I’m undecided if this within the scope of this reset. Probably my biggest deterrent is that it would use a less-than-popular selector:

a[href^="tel:"] {
  font-feature-settings: "tnum" 1, "pnum" 1, "kern" 1; /* Etc. */
}

This particular feature might be better saved for a “Going beyond Normalize-OpenType.css” set of examples, which could include the features you need to have an opinion on to use, like stylistic sets. I’m pretty open to opinions on it.

@kennethormandy As a sidebar on this, do you think it's worth while to move this out of the mindset of a normalize and into the mindset as a good set of OpenType defaults. I think potentially the notion of it normalizing is holding you back from making decisions like this one.

That said, I'm not sure you could say with any certainty which of these is the more common use case and I don't think you could write a selector that would make the right choice often enough to be worthwhile.

I think you meant to have lnum rather than pnum in your example.

a[href^="tel:"], .p-tel {
  font-feature-settings: "tnum" 1, "lnum" 1, "kern" 1; /* Etc. */
}
