Optimize Embedded Videos to Utilize Maximum HTML Element Width

I am facing an issue with embedding a Youtube video inside a td HTML element. I want the video to maintain its aspect ratio while expanding to fit the width of its parent td.

My desired look for the video is like this:

However, my current video appears like this:

Is there a way to use CSS to scale up the video to utilize the full available width of the td element while still preserving its aspect ratio?

Below is my code snippet and a link to the associated JSFiddle example:

<table width="100%">
    <tr valign="top">
        <td>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. </p>
        </td>
        <td style="width: 450px;">
            <!-- Note the YouTube video is loaded using the YouTube JavaScript API-->
            <iframe src="https://www.youtube.com/embed/zrWkRHSK6A8?enablejsapi=1" style="width: auto; height: auto;"></iframe>
        </td>
        <td>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. </p>
        </td>
    </tr>
</table>

Answer №1

To make the iframe responsive, set a max-width for it and also give the td a width based on a percentage!

Check out this JSFIDDLE for an example

<table width="100%">
  <tr valign="top">
    <td>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. </p>
    </td>
    <td style="width: 50%;">
      <!-- The Youtube video is being loaded using the Youtube Javscript API-->
      <iframe src="https://www.youtube.com/embed/zrWkRHSK6A8?enablejsapi=1" style="max-width: 100%;height: 100%;"></iframe>
    </td>
    <td>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. </p>
    </td>
  </tr>
</table>

If you're looking to resize your video while maintaining its aspect ratio, check out this JSFIDDLE for a basic idea (not created by me).

You may also want to read this article here for more information.

The trick involves adding a dummy <div> and applying padding-top:75%; to maintain the aspect ratio (adjust value according to your desired ratio).

I hope that explanation was helpful!

Answer №3

If you're familiar with the aspect ratio of a video, there's a helpful technique called "Intrinsic Ratios for Video" detailed on A List Apart.

Essentially, you create a div within the td element. Set its position: relative and adjust the padding to achieve the desired height. For instance, for a 16:9 ratio (including a 25px control bar):

div.videoWrapper {
    position: relative;
    padding-bottom: 56.25%;
    padding-top: 25px;
    height: 0;
}

Insert the YouTube iframe inside this div and apply 

position: absolute; top: 0; left: 0; height: 100%; width: 100%;
to it, like so:

iframe[src*=['youtube.com/embed/'] {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}
