    <h1>Demonstrating srcset & dynamic DPR with imgix</h1>

    <p>Using the imgix <code>w</code> and <code>dpr</code> URL parameters, we can simplify the amount of effort it takes to generate the srcset attributes on our images.</p>
    <p>This example, when viewed on a dpr 2 or 3 device will display the appropriate image. Look to the text on the lower right of the image set with imgix to confirm.</p>
