Form With Multiple Input Attributes
<form>
<input type="text" name="username" placeholder="Enter username" required minlength="3" maxlength="15" />
<input type="email" name="email" placeholder="example@mail.com" required />
<input type="number" name="age" min="1" max="99" step="1" />
<input type="password" name="password" placeholder="••••••••" required />
<input type="submit" value="Register" />
</form>🧠 Tips for Better Forms
- Use required to enforce form validation before submission.
- placeholder is great for guidance but not a replacement for labels.
- Use pattern for custom input formats like phone numbers or postal codes.
- Combine min, max, and step for better number/date input control.
Note
⚠️ Not all input types support every attribute. Always test your forms across different browsers! 🌐
