Px/Rem от jgsheppa

Many frontend developers work with pixel measurements in the form of 'px' and 'rem.' Sometimes developers need to convert from px to rem or from rem to px. There are websites which offer this functionality, but an extension for this tool feels more natural. In addition to converting from one measurement to another, you can also copy your conversions and easily paste them into your code. The extension also has a light and a dark mode, which use Github's accessibility colors as a default.
