Freeze screen in chrome debugger / DevTools panel for popover inspection?


Got it working. Here was my procedure:

  1. Browse to the desired page
  2. Open the dev console - F12 on Windows/Linux or option + + J on macOS
  3. Select the Sources tab in chrome inspector
  4. In the web browser window, hover over the desired element to initiate the popover
  5. Hit F8 on Windows/Linux (or fn + F8 on macOS) while the popover is showing. If you have clicked anywhere on the actual page F8 will do nothing. Your last click needs to be somewhere in the inspector, like the sources tab
  6. Go to the Elements tab in inspector
  7. Find your popover (it will be nested in the trigger element's HTML)
  8. Have fun modifying the CSS


To be able to inspect any element do the following. This should work even if it's hard to duplicate the hover state:

  • Run the following javascript in the console. This will break into the debugger in 5 seconds.

    setTimeout(function(){debugger;}, 5000)

  • Go show your element (by hovering or however) and wait until Chrome breaks into the Debugger.

  • Now click on the Elements tab in the Chrome Inspector, and you can look for your element there.
  • You may also be able to click on the Find Element icon (looks like a magnifying glass) and Chrome will let you go and inspect and find your element on the page by right clicking on it, then choosing Inspect Element

Note that this approach is a slight variation to this other great answer on this page.


UPDATE:As Brad Parks wrote in his comment there is a much better and easier solution with only one line of JS code:

run setTimeout(function(){debugger;},5000);, then go show your element and wait until it breaks into the Debugger


Original answer:

I just had the same problem, and I think I found an "universal" solution. (assuming the site uses jQuery)
Hope it helps someone!

  1. Go to elements tab in inspector
  2. Right click <body> and click "Edit as HTML"
  3. Add the following element after <body> then press Ctrl+Enter:
    <div id="debugFreeze" data-rand="0"></div>
  4. Right click this new element, and select "Break on..." -> "Attributes modifications"
  5. Now go to Console view and run the following command:
    setTimeout(function(){$("#debugFreeze").attr("data-rand",Math.random())},5000);
  6. Now go back to the browser window and you have 5 seconds to find your element and click/hover/focus/etc it, before the breakpoint will be hit and the browser will "freeze".
  7. Now you can inspect your clicked/hovered/focused/etc element in peace.

Of course you can modify the javascript and the timing, if you get the idea.
