Jared Toporek: “Think that web form has got your number? If you used input type=number, you may be surprised to find that it doesn’t.“
I won’t pretend to be the expert on all things related to forms. However I will say this: of all the difficult, unconventional, and unusual requirements I’ve been asked to deliver over the past 15 years, most of those tasks revolved around building forms. Each one presented a challenge that required some sort of outside-the-box or non-standard solution. I’ve learned a lot of ways to overcome those challenges: what you should do, and more importantly, what you should not do when trying to meet those challenges.
Of all the things that I’ve learned about what not to do, one of the easiest and best pieces of advice I can share is this: unless the use case is drop-dead simple, you should avoid using the number input.
