Explanation

If all the components of primary colors(either red,green or blue) are same you should write it once.

HTML supports 240 color names. eg, red,lightblue,black,yellow,etc.

Gradients represent a transitoion of a color from one shade to another across an HTML element.
Suppose wwe want to define a shade of orange to yellow for a div element of size 40px * 80px,
we will write:

1. background-image: -webkit-gradient(orange,yellow);
2. background-image:-webkit-radial-gradient(circle,white,black);
