Is it worth worrying about IE6-8 sans JavaScript when using HTML5 shiv?
I've started using HTML5, starting from the HTML5 Boilerplate. This includes modernizr, which includes a shiv to enable HTML5 elements like <header>, <footer> etc. IE6-8 will ignore these elements without the shiv, and the shiv is JavaScript, so without JavaScript IE6-8 will look like a sack of crap. I'm worried about a client looking a...

Why is it acceptable to expect that Flash will be available/enabled, but not JavaScript?
It doesn't take long when surfing the web to observe the general consensus that Flash is an expected standard, that it's okay to say "If you don't have Flash, my website won't work." Yet in the same regard, JavaScript is expected to degrade peacefully if the user does not have it enabled. I personally favor the "HTML5" approach, in oppo...
HTML5 readTransaction not supported on iPad (iOS 3.2)?
I have a HTML5 app that uses websql for storing data. Where possible, I'm using the readTransaction() method for read-only SELECT queries, and the transaction() method for INSERT/UPDATE/DELETE queries. I'm not sure if there's a performance benefit to using readTransaction(), but it seems like the right thing to do. The app works fine ...

iPad + HTML5 Video Tag + External display issue
I am using HTML5 video tags in a UIWebview on the iPad, and positioning them as needed using CSS. The key part of these videos is that they are designed to take up part, but not all, of the visible area on the page. When I'm doing this in the "normal" mode of displaying content only to the primary UIScreen, everything works great. Howe...

HTML5 elements pointless?
Don't kill me just yet, I'm asking out of pure curiosity. Elements like <section>, <nav>, <article>, <aside> etc all seem completely pointless. Sure they make everything have its own little place (and seo'd)... But it IS possible to over-organize things. There are some cases where things don't fit in any of the categories too. It also i...
