This chapter describes the different input types for the <input> element.
Input Type Text
<input type="text"> defines a one-line text input field:
Example
<form>
First name:<br>
<input type="text" name="firstname"><br>
Last name:<br>
<input type="text" name="lastname">
</form>
Last name:
Input Type Password
<input type="password"> defines a password field:
Example
<form>
User name:<br>
<input type="text" name="username"><br>
User password:<br>
<input type="password" name="psw">
</form>
This is how the HTML code above will be displayed in a browser:
User name:User password:
The characters in a password field are masked (shown as asterisks or circles).
Input Type Submit
<input type="submit"> defines a button for submitting form data to a form-handler.
The form-handler is typically a server page with a script for processing input data.
The form-handler is specified in the form's action attribute:
Example
<form action="/action_page.php">
First name:<br>
<input type="text" name="firstname" value="Mickey"><br>
Last name:<br>
<input type="text" name="lastname" value="Mouse"><br><br>
<input type="submit" value="Submit">
</form>
This is how the HTML code above will be displayed in a browser:
If you omit the submit button's value attribute, the button will get a default text:
Example
<form action="/action_page.php">
First name:<br>
<input type="text" name="firstname" value="Mickey"><br>
Last name:<br>
<input type="text" name="lastname" value="Mouse"><br><br>
<input type="submit">
</form>
Input Type Reset
<input type="reset"> defines a reset button that will reset all form values to their default values:
Example
<form action="/action_page.php">
First name:<br>
<input type="text" name="firstname" value="Mickey"><br>
Last name:<br>
<input type="text" name="lastname" value="Mouse"><br><br>
<input type="submit" value="Submit">
<input type="reset">
</form>
This is how the HTML code above will be displayed in a browser:
If you change the input values and then click the "Reset" button, the form-data will be reset to the default values.
Input Type Radio
<input type="radio"> defines a radio button.
Radio buttons let a user select ONLY ONE of a limited number of choices:
Example
<form>
<input type="radio" name="gender" value="male" checked> Male<br>
<input type="radio" name="gender" value="female"> Female<br>
<input type="radio" name="gender" value="other"> Other
</form>
This is how the HTML code above will be displayed in a browser:
MaleFemale
Other
Input Type Checkbox
<input type="checkbox"> defines a checkbox.
Checkboxes let a user select ZERO or MORE options of a limited number of choices.
Example
<form>
<input type="checkbox" name="vehicle1" value="Bike"> I have a bike<br>
<input type="checkbox" name="vehicle2" value="Car"> I have a car
</form>
This is how the HTML code above will be displayed in a browser:
I have a bike I have a car
Input Type Button
<input type="button"> defines a button:
Example
<input type="button" onclick="alert('Hello World!')" value="Click Me!">
This is how the HTML code above will be displayed in a browser:
HTML5 Input Types
HTML5 added several new input types:
- color
- date
- datetime-local
- month
- number
- range
- search
- tel
- time
- url
- week
New input types that are not supported by older web browsers, will behave as <input type="text">.
Input Type Color
The <input type="color"> is used for input fields that should contain a color.
Depending on browser support, a color picker can show up in the input field.
Example
<form>
Select your favorite color:
<input type="color" name="favcolor">
</form>
Input Type Date
The <input type="date"> is used for input fields that should contain a date.
Depending on browser support, a date picker can show up in the input field.
Example
<form>
Birthday:
<input type="date" name="bday">
</form>
You can also add restrictions to dates:
Example
<form>
Enter a date before 1980-01-01:
<input type="date" name="bday" max="1979-12-31"><br>
Enter a date after 2000-01-01:
<input type="date" name="bday" min="2000-01-02"><br>
</form>
Input Type Datetime-local
The <input type="datetime-local"> specifies a date and time input field, with no time zone.
Depending on browser support, a date picker can show up in the input field.
Example
<form>
Birthday (date and time):
<input type="datetime-local" name="bdaytime">
</form>
Input Type Email
The <input type="email"> is used for input fields that should contain an e-mail address.
Depending on browser support, the e-mail address can be automatically validated when submitted.
Some smartphones recognize the email type, and adds ".com" to the keyboard to match email input.
Example
<form>
E-mail:
<input type="email" name="email">
</form>
Input Type Month
The <input type="month"> allows the user to select a month and year.

Input Type Number
The <input type="number"> defines a numeric input field.
You can also set restrictions on what numbers are accepted.
The following example displays a numeric input field, where you can enter a value from 1 to 5:
Example
<form>
Quantity (between 1 and 5):
<input type="number" name="quantity" min="1" max="5">
</form>
Input Restrictions
Here is a list of some common input restrictions (some are new in HTML5):
| Attribute | Description |
|---|---|
| disabled | Specifies that an input field should be disabled |
| max | Specifies the maximum value for an input field |
| maxlength | Specifies the maximum number of character for an input field |
| min | Specifies the minimum value for an input field |
| pattern | Specifies a regular expression to check the input value against |
| readonly | Specifies that an input field is read only (cannot be changed) |
| required | Specifies that an input field is required (must be filled out) |
| size | Specifies the width (in characters) of an input field |
| step | Specifies the legal number intervals for an input field |
| value | Specifies the default value for an input field |
You will learn more about input restrictions in the next chapter.
The following example displays a numeric input field, where you can enter a value from 0 to 100, in steps of 10. The default value is 30:
Example
<form>
Quantity:
<input type="number" name="points" min="0" max="100" step="10" value="30">
</form>
Input Type Range
The <input type="range"> defines a control for entering a number whose exact value is not important (like a slider control). Default range is 0 to 100. However, you can set restrictions on what numbers are accepted with the min, max, and step attributes:
Example
<form>
<input type="range" name="points" min="0" max="10">
</form>
Input Type Search
The <input type="search"> is used for search fields (a search field behaves like a regular text field).
Example
<form>
Search Google:
<input type="search" name="googlesearch">
</form>

The <input type="tel"> is used for input fields that should contain a telephone number.

Add your homepage:
<input type="url" name="homepage">
</form>
