 Introduction of Css and History of Css

Cascading Style Sheets (CSS) is a simple mechanism for adding style
(e.g., fonts, colors, spacing) to Web documents

Althrogh HTML isvery essentialto generate adding
a web page bu their aresome important drawback which HTML

HTML has no style for layout
Using HTML we can’t add position of element
HTML does’t support for multiple unit like px ,em etc

Background image display using HTML repeate itself

To improve look and feel WC3 school launch a new language
called css in year 1996 .

The term css stand for Cascading Style Sheets
