<H1>runtimeStyle Object Sample</H1>

This sample demonstrates the use of the <b>runtimeStyle</b> object.
The <b>runtimeStyle</b> object allows authors to use a particular style to override an existing style specified inline or in a style sheet.

In this sample, you can select different values to be set on the <b>runtimeStyle</b> object for the preconfigured properties used for this paragraph.
When you select a new value, notice that the values for the <b>runtimeStyle</b> and <b>currentStyle</b> objects change for that property, but the <b>style</b> object does not.
When the value is cleared (select 'CLEAR' from the drop-down menu) from the <b>runtimeStyle</b> object, the property value reverts to the <b>style</b> value, and the <b>currentStyle</b> value reflects this.
