<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Twenty Seventeen: Improve display of video header and header image in modern browsers
The theme uses a hack to help the video header and header image fill the available space. This centers around `max-width: 1000%;`. It causes visual issues (zooming of the header video or image) for all users though.
This fixes that with CSS Features Queries. The hack remains for browsers that don't support Feature Queries and `object-fit`. Browsers that do support both get a better experience with a more reliable styling of the video and image header container.
