The Button That Wouldn't Click

Description

You're a PM who just shipped a landing page with a big "Get Started" CTA button. Marketing is screaming — the button looks fine but nobody can click it. You open DevTools, the button is there, it has an onclick handler, but clicks do nothing.


Your designer added a decorative overlay animation last night. The button is definitely visible. No JavaScript errors in console. The hover effect even works (CSS :hover doesn't require click-through). But actual clicks? Dead.


Look at the CSS and HTML. Something is sitting on top of that button, intercepting every click like a transparent bouncer.


Sometimes the prettiest things are the most dangerous.


What CSS declaration needs to be added to .hero-overlay to fix the button?
