CSS stands for Cascading Style Sheets. It can be used for the following purposes :
- to define style of our webpage : means we can specify the color of different portions of webpage. We can specify the color of different elements of webpage. We can make text bold, italic or underline. We can specify different font for different element.
- to define different layout for different webpages : means using css you can specify separate layout for desktop and separate layout for mobile device. Similarly you can also specify separate layout for separate width monitors.
- to control webpages display on paper : means if you print a webpage, how will it look on the paper.
As CSS is not in the scope of this course to know all the above in details you have to refer CSS course. In this course we will discuss in short when ever required.
