function init() {
var drink = document.getElementById("coffee");
drink.innerHTML = "I love tea.";
drink.setAttribute("color", "red");
}

window.onload = init;

I love coffee.

This is my code.
I have selected the element with the id "coffee" and assigned it to the variable "drink".
I changed its content with the "innerHTML" property.
And, now, I want to set a "color" attribute to the element .
What's wrong with my code ? Why is the color not changing ??
