Displaying a YouTube video with iframe full width of page

I've put a video in my site using an iframe from YouTube, while the frame is full width the video is very small within the frame. How do I make it the full width?

Answer

To make a You Tube Video full width and preserve the height (and keep it responsive) you can use the following setup.

HTML with video

<div class="videoWrapper">
    <!-- Copy & Pasted from YouTube -->
    <iframe width="560" height="349" src="http://www.youtube.com/embed/n_dZNLr2cME?rel=0&hd=1" frameborder="0" allowfullscreen></iframe>
</div>

CSS

.videoWrapper {
    position: relative;
    padding-bottom: 56.25%; /* 16:9 */
    padding-top: 25px;
    height: 0;
}
.videoWrapper iframe {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}
