Container query unsupportedContainer Query Not Supported

Specificity conflictA CSS rule is not applied because a more specific selector overrides it.
CSS specificity determines which rule wins when multiple rules target the same element. IDs are more specific than classes, which are more specific than element selectors. Inline styles override all selectors.
Increase the specificity of your selector. Use CSS layers (@layer) to manage specificity. Avoid !important as it creates maintenance issues. Use DevTools to inspect which rule is winning.
