Robustness and least power

Jeremy Keith:

As a general rule, it’s always worth asking if you can accomplish something with a less powerful technology:

• Instead of using JavaScript to do animation, see if you can do it in CSS instead.
• Instead of using JavaScript to do simple client-side form validation, try to use HTML input types and attributes like required.
• Instead of using ARIA to give a certain role value to a div or span, try to use a more suitable HTML element instead.
