HTML Input Attributes
Introduction:
HTML input attributes provide additional functionality and behavior to input elements. These attributes allow customization of input fields, enhance user experience, and ensure proper data validation.
The 'required' Attribute
The required attribute specifies that an input field must be filled out before submitting the form. It ensures that users do not skip critical fields, improving form validation and data integrity.
<input type="text" name="username" required>
The 'placeholder' Attribute
The placeholder attribute provides a short hint that describes the expected value of an input field. This text is displayed inside the input box when it is empty, guiding users on what to enter.
<input type="email" placeholder="Enter your email address">
The 'maxlength' Attribute
The maxlength attribute specifies the maximum number of characters that can be entered in an input field. It is useful for limiting user input for fields such as usernames or phone numbers.
<input type="text" maxlength="10">
The 'disabled' Attribute
The disabled attribute makes an input field unmodifiable and prevents user interaction. It is often used to indicate fields that are temporarily unavailable or read-only.
<input type="text" disabled>
The 'pattern' Attribute
The pattern attribute specifies a regular expression that the input field value must match for validation. It helps enforce a specific format, such as phone numbers, zip codes, or custom patterns.
<input type="text" pattern="[A-Za-z]{3,}" title="Only letters, minimum 3 characters">
