Forms

A form allows the user to input data. A form is a series of one or more interactive elements that allow the user to enter text or make selections.

Once the user has made their selections, the user submits the form to a server, which can process the incoming data. Therefore, although HTML can present a form, HTML alone cannot do anything with the data provided.

The <form> element encompasses all interactive elements. Each interactive element must have a name attribute so that the corresponding data can be distinguished from the other form elements.

See W3Schools for details on all of the possibilities.

We will highlight the input and select elements here.

<input>

This is the most common form element and quite versatile.

The type attribute determines the behavior of the element.

Here are a few examples:

Check Me

Initially Checked

Apples Bananas Cherries

What's your favorite color?

<p><input type="checkbox">Check Me</p>
<p><input type="checkbox" checked>Initially Checked</p>
<p><input type="text" placeholder="Enter some text..."></p>
<p><input type="password" placeholder="Say the secret word"></p>
<p>
  <input type="radio" name="fruits">Apples</input>
  <input type="radio" name="fruits">Bananas</input>
  <input type="radio" name="fruits">Cherries</input>
</p>
<p>What's your favorite color? <input type="color"></p>
