for practical use of CSS
Inline CSS are individual declarations to suggest style, or to alter style established by the default external style sheet.
An example of the use of inline style could include a change in font color to suggest a level of importance to the HTML markup. This example suggests a red background, as a warning.
Warning! Do not try this at home.
The text is marked up as: <P><SPAN STYLE="background: red; color: black">Warning!</SPAN> Do not try this at home.</P>
