Frontend Companion

domdev.let

A developer tool for frontend development. This tool allows you to visualise the dimensions of elements, much like the element inspector provided by the chrome devtool. With this extension, you can make changes to elements/components during development and visualise how it affects the dimensions, padding, and margin in real-time. Feature requests / bug reports can be submitted here: https://github.com/dominiclet/frontend-companion/issues. Icon: Flaticon.com
