Replace Inline Event Handlers with Safer Alternatives

What is this warning?

Your page uses inline event handlers (like `onclick="..."` in HTML). While functional, these can be a security risk as they're harder to protect with Content Security Policy and can be more easily exploited in XSS attacks. Modern best practices recommend using event listeners instead.

How to Fix This Issue

<button onclick="alert('Hello!')">Click me</button>

<button id="myButton">Click me</button>
<script>
  document.getElementById('myButton').addEventListener('click', function() {
    alert('Hello!');
  });
</script>
