CSS and JavaScript Website Bugs: What to Check First

Menus stop opening, buttons do nothing, styles change unexpectedly, or interactive pieces work on one page and fail on another.

Something broke

Common signs

Dropdowns do not open, sliders freeze, modals fail, buttons stop responding, CSS looks different after an update, or console errors appear when the broken feature loads.

Likely causes

JavaScript bugs often come from duplicate libraries, plugin updates, script order, missing dependencies, third-party snippets, minification, cache issues, or code written for an old template.

What to send

Send the page URL, the expected behavior, the broken behavior, recent changes, and screenshots or screen recordings if the bug is interaction-based.

Practical fix path

The first step is usually browser console and network inspection, then isolating the failing script, confirming whether the bug is global or page-specific, and applying the smallest fix that does not break related behavior.
