Placeholder in input field

[vladimirmyshkovski]

Hey.
I want to remove the placeholder and add class validate from all input fields, but after looking at the source, I did not find anywhere, wherever it could be installed on the field.

How can i do this ?

Now I use two simple lines of code:

$(':input').removeAttr('placeholder');
$(':input').toggleClass('validate');

But the best way would be to do this in templates.
