This is the Inline Style.


INTERNAL Stylesheet: Internal CSS can be added by using

tag inside the section. Internal Stylesheet is useful if the whole page has a unique style.

background-color: orange;


p {

color : red;

font-size : 24px;

font-family : verdana;




EXTERNAL Stylesheet: External CSS is useful is that case when we have a number of web pages and we can style the entire website in one CSS file. This stylesheet should not be written in the HTML code. External Stylesheet can be the included in the HTML code by giving reference to the stylesheet using the tag inside the head section. The external CSS file should have .css extension.
