Twenty Fourteen: Ensure old versions of Internet Explorer degrade gracefully

Per lancewillett in the Twenty Fourteen office hours today:

We won't officially support IE7 but happy to make sure it's usable and not horribly broken.

Meaning:

Officially, we're going to support IE8+ only. However, visitors coming to Twenty Fourteen in IE7 should see more than just a blank page. This pulls us a little away from WP's core support of IE7 & up, but the task of fixing every IE7 bug in a theme is more onerous and time-consuming than core functionality.

Bugs marked as "IE7" will mostly likely be stamped with "wontfix", however if the reporter also supplies a suggested patch, then that can be tested and applied.

Periodically, checks will be made on IE7 to make sure we're not getting White Screen of Death situations (which we shouldn't anyways), but that will be the extent of our support during the development process.

Let's leave this one open until we have the basic usability fixes done.

Still keeping an eye on this, but going to wait a bit more until we have more CSS changes done. Then we can re-test in older IE versions.

Attached a style patch for old IEs (previous to IE9)

[lancewillett]

Patch looks good, only problem I saw was in ie.css two case of padding: auto; which should be padding: 0; since "auto" isn't a valid value there.

Twenty Fourteen: first pass at older Internet Explorer browser support. Props iamtakashi, see #25036.

Oops. Thank you for spotting and fixing the errors!

Let's open new tickets for IE or browser bugs.
