Input Restrictions

HTML provides a number of input restrictions that you can use to ensure that users enter the correct type of data into your forms.

Here are some examples:

• Required: Specifies that an input field must be filled out before submitting the form.

As an example:

<input type="text" name="username" required />

• Maxlength: Specifies the maximum number of characters allowed in an input field.

As an example:

<input type="text" name="description" maxlength="100" />

• Min and Max: Specifies the minimum and maximum values allowed for a numeric input field.

As an example:

<input type="number" name="age" min="18" max="120" />

• Pattern: Specifies a regular expression pattern that the input value must match.

As an example:

<input type="text" name="phone" pattern="[0-9]{3}-[0-9]{3}-[0-9]{4}" />

• Readonly: Specifies that an input field should be read-only, and cannot be edited by the user.

As an example:

<input type="text" name="address" readonly />

• Disabled: Specifies that an input field should be disabled, and cannot be used by the user.

As an example:

<input type="text" name="password" disabled />

• Placeholder: Specifies a short hint that describes the expected value of an input field.

As an example:
