So I am creating a wordpress theme, which is looking really nice already on all modern browsers, but it seems like everything I do looks different on the iPad. Especially modern techniques like CSS linear gradient and box-shadow. They don't work at all. Also some images do not display correctly, and I have a right margin of 2px alongside the whole container.
Normally I would use a tool like Firebug or something like it to debug the code on that device. But since I don't have an iPad myself this is becomming a pain in the ass for me.
I've seen that there are tools on the internet who pretend to display my site like if I was viewing it on a real iPad, but all I get is a nice iPad frame that displays the site exactly like the browser I'm using.
So, how would you tackle this problem? How would you make sure your design works well on every device, even if you don't have one to test with?
Also, how well does the iPad support modern webstandards? Is it really true I can't use any html5/css3 techniques for it or do I just have to take a different approach for mobile devices?
