Write a Javascript

I need a client side javascript functions which can be included in an html page and executed. Two tasks: #1. It should fetch any external css and make it internal (inside <style>) and remove the external link. Please make sure that you take care of the following: a) It should resolve the paths for any other linked resource in those external css. background image, fonts, video, @imports & @fonts, etc should work fine and not give a 404 error b) should preserve the "media" property values and set them as attributes in the <style> tag. (media can be "screen", "print", etc) #2. It should base64 any background image I will buy your script only after checking that it actually works and is bug free. Best of luck!
