Introduction to CSS – Cascading Style Sheet
CSS is a powerful language. CSS is also called Cascading Style Sheet. CSS is used to design web pages because you cannot properly customize web pages through html.

Whenever we write css. So let's write over some tag. And css can be written in 3 ways.
- Inline CSS
- Internal CSS
- External CSS
The CSS was created by Hakon Wium Lie in 1994 and then published by the W3C - World Wide Web Consortium in 1996.
Inline css is used only within HTML tags. But for this we have to use the style attribute.
To write internal css we have to create style tag. Because you cannot write internal css without style tag.
To write external css, we have to create a file. And whenever we create a file of external css. So css file extension .css has to be given.
Note: - If you use any property of css inside the inline css. And use the same property in internal css or external css. So the property of external css or internal css does not work. Because that property is used in inline css.
