6. Important Attributes and Validation

To make input elements more useful and user-friendly, HTML provides several attributes:

• id: A unique identifier for the input element.

• name: Identifies the input when the form is submitted.

• value: Sets the default value of the input.

• placeholder: Shows a short hint inside the input field.

• required: Ensures the input must be filled out before submitting the form.

• readonly: Makes the input field read-only, so users can't change its value.

For better data validation, you can use attributes like:

• pattern: Defines a regular expression that the input's value must match.

• minlength and maxlength: Set the minimum and maximum length for text input.

• min and max: Define the range of acceptable values for numerical inputs.
