ID Attribute

The ID attribute is used to define a style.
See the following example:

#koo99 { color: green; font-family: verdana, arial, helvetica; font-size: 20pt}

In the style sheets, ID name is followed by a hash mark (#) for identification and it can be applied to HTML tag through the ID attribute:

<P ID=koo99>Welcome to web developer's library</P>
