HTML Statistics: 5 Take-Aways

Post from February 13, 2017, filed under .

A few quick comments on Catalin Rosu’s interesting follow-up analysis of his sampling of eight million websites. Some practices, those that can be considered commendable, are wonderful to note, others Catalin and Chris have already justly commented on, yet one or the other point drowned. I find this a great opportunity to review.

  1. Hiding DOM elements: Instead of using presentational class names we should, as always, use functional or generic names.

  2. no-js HTML class: no-js is an anti-pattern because on the one hand, the class reflects dynamic state (behavior) in a permanent fashion (structure), and on the other, links a general problem (scripting fallbacks) to a specific solution (JavaScript), and so we should avoid it (or use a different name—at Google, some teams had decided for “google”, a name that can be justified on the root element while affording the needed hook).

  3. lang: There are problems with lang, from the possibility to set language on a server level to making the issue of language detection a software problem, and in many cases we don’t need it.

  4. .clearfix vs .clear vs .cf: Naming best practices don’t yield to popularity. We should clear containers with what we have in the markup, and if there are no hooks, then we should use functional or generic names again. As for clearfixes in general, let’s just use overflow.

  5. Void elements: A bit snarky, are the people who suggest not to close void elements “for brevity” the ones who are still afraid of omitting optional tags? The recommendation is spot on, and there’s good reason to go as far as to omit everything that’s optional, for the same brevity—especially when brevity not only aids performance but also understanding.

❧ One or the other point may seem strict but what they reflect is the idea of tailoring, of only using what’s necessary and avoiding everything that’s unnecessary and, of course,—the idea of quality.
