Answer 1

You could use querySelectors:

//find first element with class 'color' within a div
//returns an element Node
[yourdiv].querySelector('.color');
//find all elements with class 'color' within a document
//returns a nodeList
document.querySelectorAll('.color');

Or getElementsByClassName:

//find first element with class 'color' within a div
//returns a nodeList with 1 or more elements
[yourdiv].getElementsByClassname('.color')[0];
//find all elements with class 'color' within a document
//returns a nodeList
document.getElementsByClassName('.color');
