What is the difference between disabled and readonly?

Q: What is the difference between disabled and readonly?

In HTML forms, both `disabled` and `readonly` restrict user interaction with form controls, but they behave differently in terms of usability and form submission. `disabled`: The input cannot be focused, edited, or submitted. It is skipped when the form is submitted. `readonly`: The input cannot be edited by the user but can still be focused, copied, and will be included in the form submission. `disabled` is often used for temporarily unavailable fields (e.g., a locked option). `readonly` is often used when values should be visible but not editable (e.g., showing a username). Username (readonly): Email (disabled): Submit
