Sweet! I always wondered what kinds of key/value pairs were valid in html5

@andykillen
Copy link

the formatting on this one

<meta name='pagename' content='jQuery Tools, Tutorials and Resources - O'Reilly Media'>

gets screwed up by the apostrophe on O'Reilly....

Thanks @andykillen. I'm not sure why I was using single quotes at all, anyway. Fixed.

Great job, fella; many thanks.

Great job, Thanks

@AliceonFire

Appears to be global replacement gone wrong, @kevinSuttle:

<meta name="subject" content="your website"s subject">

Depending on the environment, one reason to occasionally use single quoted strings is avoiding the evaluation overhead of some scripting languages.

Would be great to move this to an actual repo with a README file, so that forking works, people can submit PRs and raise issues etc.

(Initially written on https://gist.github.com/whitingx/3840905, but looks like the lists are the same - therefore the input may be valuable for some of you).

Great job, but it's already outdated - see below

  1. There are few things I couldn't find on the official website of OpenGraph:
  • <meta name='fb:page_id' content='43929265776'>
  • <meta name='application-name' content='foursquare'>
  • <meta name='og:country-name' content='USA'>
  • <meta name='og:latitude' content='37.416343'>
  • <meta name='og:longitude' content='-122.153013'>
  • <meta name='og:street-address' content='1601 S California Ave'>
  • <meta name='og:locality' content='Palo Alto'>
  • <meta name='og:region' content='CA'>
  • <meta name='og:postal-code' content='94304'>
  • <meta name='og:country-name' content='USA'>
  1. On the other side I'm missing definitely:
  • <meta property="og:locale" content="en_GB" />
  • <meta property="og:locale:alternate" content="fr_FR" />
  • <meta property="og:locale:alternate" content="es_ES" />

  1. All HTTP meta headers (http-equiv) are basically for IE9 and below. These should've been added on the back-end, see explanation: #1 and #2.

  2. According to W3C meta tags docs there are way less meta tags. Namely:

  • <meta charset="UTF-8">
  • <meta name="description" content="Free Web tutorials">
  • <meta name="keywords" content="HTML, CSS, JavaScript">
  • <meta name="author" content="John Doe">
  • <meta name="viewport" content="width=device-width, initial-scale=1.0">

However, as you'll see in point 7 around half from this list still exists, however they're considered to be bad tags.

  1. These seems to be obsolete:
  • <meta name="Classification" content="Business">
  • <meta name="HandheldFriendly" content="True">
  • <meta name="MobileOptimized" content="320">

  1. IE-related tags shouldn't be used, we (almost, almost) don't use Internet Explorer anymore.

  2. For further reading if to use any of those you may check this article, many of those tags are actually bad tags.

Hi

You have written a lot of meta name attributes of which many of are not defined meta names. Like:
So, can you please let me know, how it becomes possible to define these lot of meta names?
Is there any possibility of creating more like this?
If these are not registered then how it is possible for search engine bots to crawl all these undefined meta names?

Hope you got my point, please clarify the doubts.

thanks

@ankushkgarg, I really don't know to whom are you referring to.
