Hi, we are going to talk about the HTML5 Input element. The input element is a type of Form element that allows a user to enter data within a form. Here is an example of Input elements used within a form:

<form action="/process.php">
      <div>
        <label for="firstname">FirstName: </label>
        <input type="text" id="firstname" name="firstname">
      </div>
      <div>
        <label for="lastname">LastName: </label>
        <input type="text" id="lastname" name="lastname">
      </div>
      <div>
        <input type="submit" value="Submit">
      </div>    
  </form>

This is a Form with 3 Input fields, of which one is a submit button:

The Input element is defined by it's type attribute, which specifies the type of Input element to display. There are several types of Input elements as defined by their specific attributes. This is a list of the important Input types:

<input type="text">

The Text Input defines a single-line text field, with the default width of 20 characters for the text field.

#2. Password

  <input type="email" id="email" name="email"><br><br>
  <label for="pwd">Password:</label>

  <input type="submit">
</form>

#3. Email

---

<input type="email">

The Email Input defines a field for an email address, and the value is validated to ensure it is properly formatted as an email address. This email input below allows only one email address to be sent:

<h1>Email Input</h1>
<form action="/process.php">
  <label for="email">Enter your email:</label>
  <input type="email" id="email" name="email">
  <input type="submit">
</form>

But, this example below allows multiple email addresses to be sent:

<h1>Email Input(multiple)</h1>
<form action="/process.php">
  <label for="emails">Enter email addresses:</label>
  <input type="email" id="emails" name="emails" multiple>
  <input type="submit">
</form>

</form>

---

---

<input type="checkbox">

Checkboxes allow a user to pick one or more alternatives from a restricted set of possibilities.

  <input type="radio" id="age1" name="age" value="30">

For multiple file uploads, we would add the multiple attribute:

<h1>File Input(Multiple)</h1>
<form action="/process.php">
  <label for="myfile">Select files:</label>
  <input type="file" id="myfile" name="myfile" multiple><br><br>
  <input type="submit">
</form>

---

#8. Hidden

---

<input type="hidden">

When a form is submitted, a hidden field allows web developers to enter data that users cannot view or change. Although the data in the hidden field is not visible to the user, it is transmitted when the form is submitted. It is frequently used to contain the database record that has to be changed.

<h1>Hidden Input</h1>

<script>
function msg() {
  alert("Hello people!");
}
</script>

---

#10. Submit

---

<input type="submit">

The submit Input specifies a button that sends all form data to a form handler. In most cases, the form-handler is a server page containing a script for processing the submitted data. The form's action attribute specifies the form's handler.
In the example, the form data will be transferred to a page called process.php if you click the Submit button.

<h1>Submit Input</h1>
<form action="/process.php">
  <label for="fname">First name: </label>
  <input type="text" id="fname" name="fname"><br><br>
