Q:

I need to put a variabile in a 

Suppose to have this tag:
var variabile_colore="#efdcdc";

I need to put a variable in a tag (I think something like this but it not work) :
<style>.foot {color: variabile_colore;} </style>

Anyone can help me?

A:

I think you need to apply color property forcefully.
Please try with following.
var variabile_colore = "#efdcdc !important";
$('.foot').css('color', variabile_colore);
