Why Does jQuery's `:not()` Selector Differ from CSS's `:not()` Selector?

Why is jQuery :not() Selector Not Working in CSS?

Introduction

Despite jQuery's claim to CSS3 compliance, the :not() selector behaves differently in jQuery and CSS due to extensions made by jQuery.

Key Differences

1. Comma-Separated Lists: jQuery allows complex selector lists in :not(), while the standard :not() accepts only single simple selectors.
2. Compound Selectors: jQuery permits compound selectors within :not(), but CSS requires chaining multiple :not() clauses.
3. Combinators: jQuery can use descendant combinators in :not(), which is prohibited in CSS.

CSS Workaround

To achieve the desired behavior in CSS, use multiple :not() clauses chained together:

#sectors > div:not(.alpha):not(.beta):not(.gamma)

Conclusion

The limited functionality of the CSS :not() selector leads to inconsistencies and inconveniences when migrating from jQuery to CSS. However, advancements in CSS suggest that future versions will align more closely with jQuery's extended :not() behavior.
