🧾 HTML Form Attributes

HTML forms use various attributes to control how data is submitted and processed. These attributes define where the form data is sent, how it's sent, and how it behaves during interaction.

✅ Key Takeaway

• action controls where data is submitted.
• Use method="POST" for secure and large data submissions.
• Set enctype="multipart/form-data" for file uploads.
• target controls where the response appears.
• autocomplete improves user convenience; novalidate bypasses validation.

Understanding form attributes is essential for building secure, accessible, and user-friendly web forms.
