+
+This page demonstrates the use of the experimental [`moveBefore()`](https://github.com/whatwg/dom/issues/1255) DOM
+API available in [Chrome Canary](https://www.google.com/chrome/canary/), which has been integrated into the `hx-preserve`
+attribute of htmx, if it is available.
+
+### Getting Chrome Canary & Enabling `moveBefore()`
+
+For the demo to work properly you will need to install Chrome Canary and enable the API:
+
+* Navigate to <chrome://flags/#atomic-move>
+* Enable "Atomic DOM move"
+
+htmx takes advantage of this API in the `hx-preserve` functionality if it is available, allowing you to mark an element
+as "preserved" and having all its state preserved as it moves between areas on the screen when new content is merged in.
+This is significantly better developer experience than current alternatives, such as morphing, which rely on the 
+structure of the new page being "close enough" to not have to move things like video elements.
+
+### Demo
+
+If you inspect the video below you will see that it is embedded in a `div` element.  If you click the "View Details" 
+link, which is boosted, you will transition to another page with a video element with the same id, but embedded in
+a `figure` element instead.  Without the `moveBefore()` functionality it is impossible to keep the video playing in
+this situation because "reparenting" (i.e. changing the parent of an element) causes it to reset.
+
+`moveBefore()` opens up a huge number of possibilities in web development by allowing developers to completely change
+the layout of a page while still preserving elements play state, focus, etc.

+### Demo
+
+Note that the video kept playing, despite the fact it is now a child of a `figure` element.  And you can click back
+and the video should continue to work as well.  I enjoy flipping back and forth.

+
+#### Background
+
+Rickrolling or a Rickroll is an Internet meme involving the unexpected appearance of the music video to the 1987 hit
+song "Never Gonna Give You Up", performed by English singer Rick Astley. The aforementioned video has over 1.5 billion
+views on YouTube. The meme is a type of bait and switch, usually using a disguised hyperlink that leads to the music
+video. When one clicks on a seemingly unrelated link, the site with the music video loads instead of what was expected,
+and they have been "Rickrolled". The meme has also extended to using the song's lyrics, or singing it, in unexpected
+contexts. Astley himself has also been Rickrolled on several occasions.
+
+The meme grew out of a similar bait-and-switch trick called "duck rolling" that was popular on the 4chan website in
+2006. The video bait-and-switch trick grew popular on 4chan by 2007 during April Fools' Day and spread to other Internet
+sites later that year. The meme gained mainstream attention in 2008 through several publicised events, particularly when
+YouTube used it on its 2008 April Fools' Day event.
+
+Astley, who had only returned to performing after a 10-year hiatus, was initially hesitant about using his newfound
+popularity from the meme to further his career but accepted the fame by Rickrolling the 2008 Macy's Thanksgiving Day
+Parade with a surprise performance of the song. Since then, Astley has seen his performance career revitalized by the
+meme's popularity, and Rickrolling saw a massive resurgence online in the early 2020s.
