function changeBGColor(){
// Selecting elemens by Class Name
bgElements = document.getElementsByClassName("classColor");
// When we use class name, A single element is not select instead a object is returned
// Hence we will be looping the element object.
var start;
for (start = 0; start < bgElements.length; start++) {
// Changing background color
bgElements[start].style.backgroundColor = "red";
}
}
