How to have horizontal scroll in a div with responsive width

I want to have one <div> with id that has horizontal scroll, but the problem is it has to be responsive, not with fixed width.

html, body {margin: 0; padding: 0;}

#myWorkContent{
    width:530px;
    height:210px;
    border: 13px solid #bed5cd;
    overflow-x: scroll;
    overflow-y: hidden;
    white-space: nowrap;
}

#myWorkContent a {
    display: inline-block;
    vertical-align: middle;
}

#myWorkContent img {border: 0;}

<div id="myWorkContent">
     <a href="assets/work/1.jpg"><img src="http://placekitten.com/200/200/" height="190"></a>
     <a href="assets/work/2.jpg"><img src="http://placekitten.com/120/120/"/></a>
     <a href="assets/work/3.jpg"><img src="http://placekitten.com/90/90/" height="90" width="90"></a>
     <a href="assets/work/4.jpg"><img src="http://placekitten.com/50/50/" height="190"></a>
     <a href="assets/work/5.jpg"><img src="http://placekitten.com/100/100/"></a>
     <a href="assets/work/6.jpg"><img src="http://placekitten.com/200/200/" height="190"></a>
</div><!-- end myWorkContent -->

The problem is with that 530px. I would like to use 100% instead. But then I got page scroll and scroll of the DIV goes right, can not get it, any idea?

Just set your width to auto:

#myWorkContent{
    width: auto;
    height:210px;
    border: 13px solid #bed5cd;
    overflow-x: scroll;
    overflow-y: hidden;
    white-space: nowrap;
}

This way your div can be as wide as possible, so you can add as many kitty images as possible ;3

Your div's width will expand based on the child elements it contains.
