This linked demo is fascinating: on the left hand side you can edit HTML with inline styles, and the right hand side then updates live to show that content rendered by Dropflow in a canvas element.
Why would you want this? It lets you generate images and PDFs with excellent performance using your existing knowledge HTML and CSS. It’s also just really cool!
