Alternative text on `<applet>` elements is important for users who do not have a Java-capable browser or have disabled Java™. In addition, providing a text alternative makes the same information accessible through audio or other channels. <!-- This is where the code snippet is injected --> <div id="locSnippet"></div> ### What to do * If the `<applet>` element is missing an alternative description, add an `alt` attribute * **And**, add HTML-based content (i.e., inner text) that describes the function of the `<applet>` element, if possible. For example: ``` <applet CODE="banner.class" ALT="Scrolling news banner" WIDTH="200" HEIGHT="200"> Banner shows three things: <ol> <li>The Dow Jones Industrial Average climbed 300 points today in heavy trading.</li> <li>G8 Summit to start in Washington tomorrow.</li> <li>Global nuclear non-proliferation treaty signed by all nations today.</li> </ol> </applet> ``` </script></mark-down> <!-- End main panel --> <!-- This is where the rule id is injected --> <div id="ruleInfo"></div> </div> <div class="bx--col-sm-4 bx--col-md-3 bx--col-lg-4 toolSide"> <!-- Start side panel --> <mark-down><script type="text/plain"> ### About this requirement * [IBM 1.1.1 Non-text content](https://www.ibm.com/able/requirements/requirements/#1_1_1) * [H35: Text alternatives on applet elements](https://www.w3.org/WAI/WCAG22/Techniques/html/H35) ### Who does this affect? * People using a screen reader, including blind, low vision, and neurodivergent people * People using text-based browsers (e.g., Lynx) or audio interfaces </script></mark-down> <!-- End side panel --> </div> </div> </div> </body> </html>
