Viewport Dimensions: Chrome Extension for Displaying Window Size

'Viewport Dimensions' is a Chrome extension designed to show real-time Chrome’s viewport dimensions in the lower right corner of the browser window. It's widely used for accurate testing of websites and screen recording at precise dimensions. It includes settings for visibility duration, display location, color customizations, and inner/outer dimensions display toggle. The extension also recently resolved overlapping issues with website elements and made it compatible with offline use and 'file:///' URLs.

Extension summary

This extension displays Chrome’s viewport dimensions in the lower right corner of the browser window when resizing the browser. Very handy when you want to make the browser window a specific size for testing websites or if like me you want to make the viewport precisely 1920x1080 when recording screencasts at 1080p.

*** NOTE: Chrome requires you to RESTART Chrome before this extension is fully loaded.

*** UPDATED v0.0.7 *** With the release of 0.0.7 I have added some new features, you can now set the amount of time the dimensions should remain visible for, the location on the screen the dimensions should appear, the background color, the text color, and size, and you now have the option to enable/disable both the inner/outer dimensions.

*** UPDATED v0.0.6 *** FIX: I fixed an issue where sometimes the viewport details panel would hide behind website elements, to fix this I have increased the z-index to the maximum number.

*** UPDATED v0.0.5 *** FIX: I fixed the error that would show up in the Chrome console. NEW: I upgraded jQuery to v1.11.1

Doesn't work on 119

Pure garbage, doesn't work even after restarting Chrome. Tried everything. Trash!

It's great when it works. Lightweight and simple. But it randomly decides not to work at times so you can't depend on it.
