HTML <input> alt-egenskab

HTML <input> tag

Definition og brug

alt Egenskaber giver brugere alternativ tekst, hvis de pga. en eller anden grund ikke kan se billedet (pga. langsom forbindelse, fejl i src-egenskaben eller hvis brugeren bruger en skærmlæser).

Note:alt Egenskaber kan kun være med <input type="image"> use together.

Note:even alt The attribute is not a required attribute, but it should still be set when the input type is image. If this attribute is not used, it may cause usability issues for text browsers or non-visual browsers.

Example

<form action="/action_page.php">
  <label for="fname">Name:</label>
  <input type="text" id="fname" name="fname">
  <input type="image" src="submit.gif" alt="Submit" width="48" height="48">
</form>
