Hi Mau'Kauba Nibabe you could have tried it first by yourself before posting the question and then answering it.

Answer 2

✍Hi Avinesh, I tried it and didn't realize the difference so I post the question.
🙏Then I waited for people to answer but no one did.
✔So I went back and tried doing it again, and then I realized the difference.

✍Got it:
✔The value attribute puts actual content inside of a form, so if you want to change it you have to delete it first.

✔While the placeholder attribute puts an image of content inside of a form, so when you click on the box and start typing it disapears.

✔ Placeholder is used more so to specify what the input box is for, were as the value will give a default value.
