The <input> element relies on the type attribute to specify acceptable values during form entry. Different input types include text, email, number, password, etc.
* Input Types: The type attribute determines the kind of input control and the acceptable values for that control.
* Usage Example:
<input type="email" placeholder="Enter your email">
<input type="number" min="1" max="10">
These input elements specify acceptable values for email and number inputs respectively.
