css scroll with overflow property does not work
<p>I am trying to have a vertical scrollbar in the body of page. which should be implemented by css.</p>

<p>I don't want to use fixed height.</p>

<p>I used following code in my css:</p>

<pre><code>.summary-scroll {
   overflow-y: scroll;
   overflow-x:hidden;
   height: 100%;
}
</code></pre>

<p>but it does not work. 
But when I add just an attribute named: layout="column"  (without any need to have class attribute) the body has scrollbar.</p>

<p>I don't know what is the relation between layout and scrolling?
Also I have to implement it in my css , what is the solution for handling in css file?</p>
