Not sure how all the individual HTML 5 features shown on the following site translate into what Freeway allows us to do, but at least you can see how IE7 and IE8 compare with a modern browser like Chrome:
For those of you who care about browser compatibility with IE (which is usually determined by the number of IE using visitors to your site), keep in mind that IE8 is the newest version of IE you can run on Windows XP; and Windows XP is shockingly still very widely used OS.
And while we’re on this subject, what should these settings be for each page?
Code: More Readable or More Efficient
Compatible: Normal, IE6, IE7, or IE8
Language: Currently set to None
Encoding: Currently set to Unicode 6.1 UTF-8
Code: More Readable or More Efficient? More efficient just strips out the white space and line breaks that make it easy to read as a human. The trade-off is that the load times will be a tiny bit faster, but as a rule choose more readable.
Compatible: Normal, IE6, IE7, or IE8? IE8 here too, it’s the latest version that will run on XP.
Language: Currently set to None. I change mine to English. Search engines having that info, and it helps auto translators.
Encoding: Currently set to Unicode 6.1 UTF-8 Unicode. Leave this as is.
