<style>
.effect
{
background-color:#0099FF;
font:Arial, Helvetica, sans-serif;
}

</style>
<body> 
<div ng-app=""> 
<form>

Check to show this: 
<input type="checkbox" ng-model="myVar"> 
</form>
<div class=effect>
<h2 ng-show="myVar">Hello! About Vision Computers </h2>
<p ng-show="myVar">

</div>

<p>The ng-show attribute is set to true when the checkbox is checked.</p>
