Re: 회신: Re[2]: Our next step: Web-based Signage Player Requirements

Hi Sunghan,

Thanks for checking my demo.
My demo doesn't support IE8, IE9.
But it supports IE10 on Windows 8.

I know html5shiv well.
It's very famous script among web developers.
I often use it when I make a HTML5-based web site.
It solves the DOM structure problems for unknown elements
(e.g. <section>, <article>, etc.) so that CSS style can be 
styled to unknown elements as expected.
But it is not a polyfill for new APIs and CSS features.
Even if I use it, my demo won't work well in IE8.

Anyhow, I won't support old browsers for the demo.
I'd like to focus on the latest browsers.

Cheers,
Futomi
