Build an HTML Form That Posts

Create a form whose action targets a route.

Why Forms Matter

An HTML form is how a browser collects typed input and hands it to your server. It is the front door for almost every user action. 📝

The form Element

Everything starts with a form tag. The browser bundles whatever fields live inside it and sends them together when the user submits.

<form>
  <!-- fields go here -->
</form>
