HTML Form Tag: A Comprehensive Guide with Examples

1. Open and close the form tag:

<form>...</form>

2. Set the 'action' attribute to the URL of the page that will process the form data:

<form action='process-form.php'>...</form>

3. Set the 'method' attribute to 'get' or 'post' depending on how you want to submit the data:

<form action='process-form.php' method='post'>...</form>

4. Inside the form tag, you can add input fields such as text fields, checkboxes, radio buttons, and more:

<form action='process-form.php' method='post'>
  <label for='username'>Username:</label>
  <input type='text' id='username' name='username'>

  <label for='password'>Password:</label>
  <input type='password' id='password' name='password'>

  <input type='submit' value='Submit'>
</form>

5. Finally, add a submit button to the form:

<input type='submit' value='Submit'>

When the user clicks on the submit button, the form data is sent to the URL specified in the 'action' attribute using the 'method' specified in the 'method' attribute.
