    So I went to trusty html2canvas It works really well with some caveats; which I hit. It does not render SVG backgrounds well, or complicated CSS3 gradients. To hack this I basically append a png background if screenshot is occurring, this happens only if the og:image hasn't been created/uploaded before. - Source: dev.to / 5 days ago

I wrote code and it worked as I thought except for one part. Everything was fine in the screenshot, except the preview part. IT WAS BLANK, LIKE COMPLETELY BLANK. Oh my god! How is this possible? What on earth is wrong that every solution I... - Source: dev.to / 11 months ago
  • A Firefox-Only Minimap
    That's slightly harder, but still possible by first rendering the HTML onto a canvas. Example here: http://html2canvas.hertzen.com/. - Source: Hacker News / almost 2 years ago
