HTML <input> alt Attribute HTML <img> HTML <ins>

The alt attribute on an <input> tag defines alternative text.

This attribute only applies to <input> elements of type image.

Alternative text only shows when the image cannot be loaded.

Example

#

An alt attribute on an <input> element. The image button is loaded correctly, therefore alternative text does not display.

First name Last name <form action="/tutorial/action.html"> <label for="firstname">First name</label><br /> <input type="text" id="firstname" name="firstname"><br /> <label for="lastname">Last name</label><br /> <input type="text" id="lastname" name="lastname"><br /><br /> <input type="image" alt="Submit" width="40" height="40" src="/img/html/arrow.png"> </form> Try it live

In this example the image name has a typo and cannot be loaded. The alt text displays next to an icon of a broken image. The submit button is still functional.

First name Last name <form action="/tutorial/action.html"> <label for="firstname">First name</label><br /> <input type="text" id="firstname" name="firstname"><br /> <label for="lastname">Last name</label><br /> <input type="text" id="lastname" name="lastname"><br /><br /> <input type="image" alt="Submit" width="40" height="40" src="/img/html/arrarow.png"> </form> Try it live
