CSS: strong

Defines the properties for a block of text formatted as "strong."

Platform Support

IE	Netscape	Mozilla	Opera	Safari
2.0+	1.0+	1.0+	4.0+	1.0+

Example

This example sets the font-weight for all "strong" elements to "bolder", which is darker than the standard "bold":

strong { font-weight: bolder; }

Remarks

You will usually style individual span elements by assigning classes and id's to them and styling those. Assigning the same styles to all span elements usually is not very useful.
