A form should feel easy to use. The visitor sees a question, gives an answer, and needs to know what will happen next.
What You Need to Know
Required is checked during normal form submission for supported inputs. Removing the attribute removes that specific rule.
Try the Example
Take a look at the example. We’ll explain the important lines right below it.
<form action="/join" method="post">
<label for="email-address">Email</label>
<input id="email-address" name="email" type="email" required>
<button type="submit">Join</button>
</form>
<p>Try removing required and observe the change.</p>Let’s Read the Code
- required: Required asks the browser to stop a normal submission when this control has no acceptable value.
- <form>: The form groups controls and identifies where submitted data goes.
- <label>: The label tells people what the input is for. A matching for/id pair makes the label clickable.
- for: For connects a label or output with a control by ID.
Read the named elements and attributes together. They explain how the browser connects this feature to the rest of the page.
What Happens in the Browser?
The HTML controls work in the browser, but saving an answer requires the example action path to be handled by a real server.
Where does the answer go? The example uses the submitted name(s) email. Those names help the receiving server identify each answer. A label is for people; a name attribute is for the form data; an ID connects elements in the page.
Your Turn
Remove required, then restore it and test with an empty email.
Common Beginner Mistakes
- Copying the example without giving the fields a clear label and a usable name.
- Required does not apply to every input type, and formnovalidate can bypass native checks.
Key Takeaways
- A control needs a clear label and, when submitted, a meaningful name and value.
- required: Required asks the browser to stop a normal submission when this control has no acceptable value.
- Remember that HTML form rules help the visitor, but server-side code must decide whether received data is valid.
