<h2>Definition</h2>
<p>The counter-increment property sets how much the counter increments on each
occurrence of a selector. Default increment is 1.</p>
<b>Note:</b> If "display: none" is used you should <b>not</b> be
able to increment the counter. If "visibility: hidden" is used you <b>should</b>
be able to increment the counter.
<p><b>Inherited:</b> No</p>
<hr />
<h2><b>JavaScript Syntax</b></h2>
<p>CSS properties can also be dynamically changed with a JavaScript.</p>
<p><b>Scripting Syntax:</b> <i>object</i>.style.counterIncrement="section 2"</p>
<p>In our HTML DOM tutorial you can find a full
<a href="../htmldom/dom_obj_style.asp">Style Object Reference</a>.</p>
