                        CSS (Cascading Style Sheets) is a stylesheet 
                        language used to design the webpage to make 
                        it attractive. The reason of using CSS is to 
                        simplify the process of making web pages 
                        presentable. CSS allows you to apply styles 
                        to web pages. More importantly, CSS enables 
                        you to do this independent of the HTML that 
                        makes up each web page.
