you can hide div in 2 popular ways:

(1) hide using css

add display:none div hide div whether js enabled or not. can use this:

<div id="adiv" style="display:none"> </div>

(2) hide using js

hiding via js useful if don't want div hidden users don't have js enabled. there various ways hide div using automatically executing js. below simple way this.

<body onload="hideshow(document.getelementbyid('adiv'));">  <a href= "javascript:hideshow(document.getelementbyid('adiv'));";>clickme!</a>   <div id="adiv"> </div>
