I wanted a way to customize the "no hello" message like the one found at nohello.net. So I made a website that lets you create your own "good practice" to share with others hopefully educating people and saving everyone time.
Thank you for the feedback, this is the first time I have made a website with such contrasting colors. Usually when I go with a "dark mode" I make sure not to go fully black or fully white because of the reason you mentioned. With that said, I don't have a problem reading the text with this color scheme. However, you are not the first person to mention this so far. I have made the update, hopefully that's easier on the eyes.
Don't do this: black on black text like you do on that site
Do this instead: text you can read
(and I can't make this on your site because I can't read the text in the chat)
