It recommends using default WordPress HTML markup for widget settings while adding CSS, images, and JavaScript interactions to enhance the look and feel and make the settings easy to understand and interact with. Examples of enhancements include CSS for alignment and styling, Bootstrap for inputs, iPhone-style on/off switches, images for radio buttons, and JavaScript for features like show/hide elements and number sliders.
