There is a special and pretty secret mode in browsers, called design mode.
When you set a page into design mode, you can edit the content of the page directly inside the browser page, which is very handy to test some prototype or check out how a new headline would look, for example.
How do you enable it? Open the DevTools console, and type:
document.designMode = 'on'
The same result can be triggered by enabling
contentEditable on the
body element, like this:
document.body.contentEditable = true
You can edit text, delete it, and also drag images around to reposition them.
You can turn off the mode by using
document.designMode = 'off'
This feature is supported by almost every browser, IE included. It’s pretty old, but quite unknown.
