What is CSS?

* CSS stands for Cascading Style Sheets

* Styles define how to display HTML elements

* Styles are normally stored in Style Sheets

* Styles were added to HTML 4.0 to solve a problem

* External Style Sheets can save you a lot of work

* External Style Sheets are stored in CSS files

* Multiple style definitions will cascade into one

 

What style will be used when there is more than one style specified for an HTML element?

Generally speaking we can say that all the styles will "cascade" into a new "virtual" style sheet by the following rules, where number four has the highest priority:

1. Browser default

2. External style sheet

3. Internal style sheet (inside the <head> tag)

4. Inline style (inside an HTML element)

So, an inline style (inside an HTML element) has the highest priority, which means that it will override a style declared inside the <head> tag, in an external style sheet, or in a browser (a default value).
