HTML Input tag

Example

A simple HTML form with two input fields and one submit button:
<form action="form_action.asp" method="get">
  First name: <input type="text" name="fname" /><br />
  Last name: <input type="text" name="lname" /><br />
  <input type="submit" value="Submit" />
</form>


Definition and Usage

The <input> tag is used to select user information.
An input field can vary in many ways, depending on the type attribute. An input field can be a text field, a checkbox, a password field, a radio button, a button, and more.

Browser Support


The <input> tag is supported in all major browsers.

Differences Between HTML and XHTML

In HTML the <input> tag has no end tag.
In XHTML the <input> tag must be properly closed.

Tips and Notes

Tip: Use the <label> tag to define labels for input elements.
