<div id="div1" style="width:80px;height:80px;background-color:red;"></div>
<br>
<div id="div2" style="width:80px;height:80px;background-color:green;"></div>

<div id="div3" style="width:80px;height:80px;background-color:blue;"></div>

The fadeToggle() method toggles between the fadeIn() and fadeOut() methods.

If the elements are faded out, fadeToggle() will fade them in.

If the elements are faded in, fadeToggle() will fade them out.

Hidden elements will not be displayed at all.

They no longer affect the layout of the page.
