In an individual element's STYLE attribute:
This paragraph is red.
<P STYLE="color: red"> This paragraph is red. </P>
Declarations can also be used as the value of an element's style attribute. These declarations will only affect that element.
In general, it is best not to use this technique because it creates a hard coded style within the HTML file's BODY which will be hard to find and update later. It is better to assign the element a unique ID and define a unique style for that ID in an external style sheet.
