That made me think... it should be pretty easy to set that attribute on every element in the DOM (overkill, but then it makes every piece of text on the page editable, poof!) I can imagine giving that to not-too-technical users to play with changing things on a page - as long as they could paste a one-liner into the dev console:
Editable content also supports rich text copy-and-paste, so you can literally control+c a portion of a site and control+v into a content-editable, and it will look exactly how it did on the other site :D
Just before you get too far down the content-editable-is-amazeballs rabbit hole I have to have a quick talk with you.
Sadly, the cross browser support situation is pretty flaky. In practice this means you’ll find a lot of variance in the user input you get depending on which browser it’s coming from. Makes it really difficult to keep styling consistent or parse the content of it.
Sadly this is one of those times we can’t have nice things.
Second this- it's my go-to when I just need some quick notes that won't be saved. I've thought about making a version with little markdown helps like automatic bulleting, but I like the simplicity as-is.
