- It is used for sending sensitive data
- Example syntax:
<form action="demo_form.asp">
Form Elements: Action
- "Action" instructs the browser where to send collected data
- It can be an absolute URL, pointing to another website, or a relative URL, pointing to a file within a website
- Example absolute URL:
<form action="http://www.w3schools.com/css/default.asp"> - Example relative URL:
<form action="aboutme.html">
Fieldset and Legend Elements
- Fieldset and legend elements work together
- A fieldset groups related form elements within a drawing
- A legend is the caption for the fieldset or element group
Label Element
- The
<label>element is a text that informs the user what the data entry is about - The "for" attribute directly links the
<label>element to its related<input>element - The "for" attribute value should match the "id" attribute of the input
Input Element

- Label is used to label a control
- Type specifies the kind of control for the
<input>element - Name distinguishes which data comes from a given control, which is used for referencing in JavaScript
- ID identifies controls on the page to give the label a referral point
Password Syntax
<label for="password">Your password: </label><input type="password" id="password" name="password">

- Checkbox controls let users pick a combination of options
- Radio button controls allow a user to choose from mutually exclusive options

<textarea>element captures large amounts of text, useful for user feedback, comments, and suggestions - The submit button finalizes everything and submits the data to the server
