        /*  This is the constant aspect ratio trick
            Percentages in padding-top declarations are based on the width of the
            parent element. We can use this trick to achieve a constant aspect ratio
            for video-container-inner by setting height to 0.

            So the video height will decrease if the browser window is narrow,
            but it will keep same aspect ratio. Must use absolute positioning on
            video to keep it inside its container since the container's height is 0.

            However, because we widen the video player longer than the video's
            intrinsic width for long video to make scrubbing easier, we can't use
            the aspect ratio to set the height. The height needs to be the
            intrinsic height in these cases. So we use a media query so aspect
            ratio trick is only used if page width is less than or equal to
            intrinsic video width.
