HTML

What's the difference between readonly and disabled in form controls? I found myself asking this question when implementing a very specific feature.

I'm making a form to send data, but I also want to include some generic information that the user doesn't need to enter. So I added another <input> element and gave it a visually-hidden class. But then I was faced with a question...do I set it to disabled or readonly?

After consulting this thread, I settled on readonly because it appears that the value of disabled inputs won't be sent when the form is submitted.
