To set the list properties in a single declaration, use the listStyle property in JavaScript.
Example
You can try to run the following code to set the listStylePosition and listStyleType property in one declaration with JavaScript −
<!DOCTYPE html> <html> <body> <ol id="myID"> <li>One</li> <li>Two</li> </ol> <button type="button" onclick="display()">Change style</button> <script> function display() { document.getElementById("myID").style.listStyle = "circle outside"; } </script> </body> </html>
