How to diasble scrolling (y-axle) with php
<p>I am making an off canvas menu and I'm done with it. I jut want to disable the scrolbar after clicking it because it doesn't expand the whole page. But... I'm kinda stuck. I want to disable it vartically .I wanted to do it with PHP but all I got was:</p>

<pre><code>&lt;?php

if (sender.Id == "open-button")
{
 ; 
}

?&gt;
</code></pre>

<p>The code of the button is:</p>

<pre><code>&lt;li&gt;&lt;a href="#" class="fa fa-bars  fa-3x" id="open-button"&gt;&lt;/a&gt;&lt;/li&gt;
</code></pre>

<p>Help would be awesome because I'm kinda stuck</p>

<p>Thank you in advance!!</p>
