HTML Input Attributes

Input attributes modify how input fields behave and are validated. Attributes like placeholder, required, min, max, and pattern offer guidance and constraints, ensuring cleaner data and better user experience.

Key Topics

Common Input Attributes

  • placeholder: Hint text inside the field
  • required: Field must not be empty
  • min, max: Numeric or date range limits
  • pattern: Regular expression for validation

Attributes Example

This example shows a required email field with a placeholder and pattern. A full code sample is provided below.

<form>
    <label>Email:</label>
    <input type="email" name="email" placeholder="you@example.com" required pattern=".+@.+\..+">
    <button type="submit">Submit</button>
</form>

Explanation: The required attribute prevents form submission if empty, placeholder guides the user, and pattern ensures the input matches an email-like format.
