Placeholder does not work in IE

Placeholder does not work in IE

  
The place holder is not rendered in gray color, but regular black color. I am using IE 11, it works fine in Chrome.
Does anyone know why and how to fix it?
Hi Wei li,

What do you mean by placeholder. In your screenshot I can only see an input text field. Is that what you meant?

Can you describe why did you expect gray color (was it disabled)?

Cheers,
Guilherme
