Lazy load embedded YouTube videos
This looks like an interesting approach to speeding up the rendering of pages on this site. The primary source of slowdown on this site is YouTube embeds. Now that I’ve fixed YouTube’s embed sizing issues here, I want to finish things off by replacing them with façades such as this. I’ll experiment with this, and if it doesn’t seem to do what I want, I’ll try something with <div>
elements and some Javascript.
