Add-on summary

Analyze keywords

This extension measures the dimensions from your mouse pointer up/down and left/right until it hits a border. So if you want to measure distances between elements on a website this is perfect. It doesn't really work with images because there the colors change a lot pixel to pixel.

Images & HTML Elements

Measure between the following elements: images, input-fields, buttons, videos, gifs, text, icons. You can measure everything you see in the browser.

Mockups

Your designer handed you mockups as PNGs or JPEGs? Just drop them into Chrome, activate Dimensions and start measuring.

Thank so much!

Fix this: 1) default and configured hotkey does not work; 2) turning off with the Esc button does not work.
