Is HTML5 and CSS3 supported by HTA? If I am planning to use my application only with Windows operating system: It is a simple application that does some basic file handling, is HTA a viable option?
Will there be any serious performance issues if I use a simple flat file (text file) to store data of my HTA?
To summarize, you have to include such kind of meta line in your HTA to make it support CSS3:
<meta http-equiv="x-ua-compatible" content="ie=9">
