STRONG
The text between the opening and closing STRONG statements will, in most browsers, be displayed in a boldface font. It is recommended you use the B tag instead for more consistant results across the full range of browsers. For example:
<P> The Empire State building is <STRONG>HUGE!</STRONG> </P>
STRONG Attributes:
CLASS=" ... "
This attribute indicates the style 'class' applicable to the tag to which it has been assigned, the style 'class' being a function of a style sheet. For example, assume the style class 'relaxed' includes text with a font size of 8, and the style class 'active' includes text with a font size of 12. Using the CLASS="relaxed" attribute with a tag will cause the text within that tag to be displayed with a font size of 8. Using the CLASS="active" attribute with a tag will cause the text within that tag to be displayed with a font size of 12.
ID=" ... "
The ID attribute is used to assign a unique ID selector (identification) to the tag in which it is invoked. A style may be assigned to that ID, which will effect only that one instance of the attribute.
STYLE=" ... "
Used to specify which style sheet commands to apply to the instance of the STYLE attribute invoked within the tag.
TITLE=" ... "
The TITLE attribute is used to display a note or information in a popup window pertaining to the object to which it was assigned. The popup window is invoked by holding the mouse pointer over the object.
