The input Element
The HTML input element is the most used form element.
An input element can be displayed in many ways, depending on the type attribute.
Here are some examples:
| Type |

| <input type="text"> |

HTML Input Type
The Fields
The
<input type="text"> define a single-line field for text input.
Example
A form with fields for text:
<form>
<label for="fname">First name:</label><br>
<input
type="text" id="fname" name="fname"><br>
<label for="lname">Last
name:</label><br>
<input type="text" id="lname" name="lname">
</form>
This is how the html code above will be displayed in a browser
note:The form itself is not visible.Also note that the default width of an input field is 20 characters.
The <label> Element
Notice the use of the <label> element in the example above.
The <label> tag defines a label for many form elements.
The <label> element is useful for screen-reader users, because the screen-reader will read out loud the label when the user focuses on the input element.
The <label> element also helps users who have difficulty clicking on very small regions (such as radio buttons or checkboxes) - because when the user clicks the text within the <label> element, it toggles the radio button/checkbox.
The for attribute of the <label> tag should be equal to the id attribute of the <input> element to bind them together.
Radio Buttons
The
<input type="radio"> define a radio button.
Radio buttons let a user select ONE of a limited number of choice.
Example
A form with radio buttons:
<p>Choose your favorite Web language:</p>
<form>
<input type="radio" id="html" name="fav_language"
value="HTML">
<label for="html">HTML</label><br>
<input
type="radio" id="css" name="fav_language" value="CSS">
<label
for="css">CSS</label><br>
<input type="radio" id="javascript"
name="fav_language" value="JavaScript">
<label for="javascript">JavaScript</label>
</form>
This is how the HTML code above will be displayed in a browser:
choose your favorite Web language:
Checkboxes
The
<input type="checkbox"> defines a
checkbox.
Checkbox let a user select ZERO or MORE option of a limited number of choices.
Example
A form with checkboxes:
<form>
<input type="checkbox" id="vehicle1" name="vehicle1" value="Bike">
<label for="vehicle1"> I have a bike</label><br>
<input
type="checkbox" id="vehicle2" name="vehicle2" value="Car">
<label for="vehicle2">
I have a car</label><br>
<input type="checkbox"
id="vehicle3" name="vehicle3"
value="Boat">
<label for="vehicle3"> I have a boat</label>
</form>
This is how the HTML code above will be displayed in a browser
The Submit Button
The <input type="submit"> defines a button for submitting the form data to a form-handler.
The form-handler is typically a file on the server with a script for processing input data.
The form-handler is specified in the form's action attribute.
example
A form with a submit button:
<form action="/action_page.php">
<label for="fname">First
name:</label><br>
<input type="text" id="fname" name="fname"
value="John"><br>
<label for="lname">Last name:</label><br>
<input type="text" id="lname" name="lname" value="Doe"><br><br>
<input type="submit" value="Submit">
</form>
