page is not scrolling vertically in mobile devices
<p>I'm working on a project. There is an issue on the front end side. The site is responsive, but when I view it in mobile width <em>(specially for iPhone 4 &amp; 5)</em>, the vertical scroll doesn't work. </p>

<p>I'm not using any div that needs scrolling, the  whole page is not scrolling vertically, I'm afraid I can't provide the code. The thing I wanna know is why does this happens? and what would I've possibly done wrong?</p>

<p>1) I have added <code>-webkit-overflow-scrolling:touch</code> on body tag but my chrome browser is not picking it up and saying invalid property.</p>

<p>2) I have added <code>body{overflow-y:scroll,position:relative}</code> Now its showing a scroll but there is no bar between the scroll, and its pretty much stuck there.</p>
