Every time I enter in dbdiagram.io I run this in the console:
document.querySelector('#chart').style.backgroundColor = '#212121'
You can see the result here IMHO looks way better than the default one, is nicer to the eye, matches perfectly with the default header and sidebar and makes the tables and relations visible at first glance.
Iām using Greasemonkey now so it runs automatically when I enter but when I share with people their eyes bleed
