What is difference between .htc and .js file?

Question

What is difference between .htc and .js file? Can we convert any .htc file to a .js file?

The problem is if we use htc to make png fixes, then we add htc to css fil

Answer 1

A htc-file is a behaviour-file, have a look at MSDN

Answer 2

Technically, you can use conditional comments to allow the code to validate.

A hack is a hack, it's just weird that MS made this hack in a way that it's a valid hack.

Now, something else to consider - are you using a JavaScript library? Then you should be using the library to do this functionality, which would eliminate the need for the HTC (which needs JavaScript enabled to run).
