In the context of the provided code, what are the implications of using non-clickable elements like 'i' and 'span' for interactive functionality, and how can this be improved for better accessibility and usability?
Using non-clickable elements like 'i' and 'span' for interactive functionality can be problematic for accessibility and usability as these elements are not inherently interactive and may not be accessible to all users, such as those using screen readers or keyboard navigation. To improve accessibility and usability, it is recommended to use semantic elements like buttons or links for interactive functionality.
<button onclick="myFunction()">Click me</button>
