When it comes to CSS selectors, pseudo-classes play a vital role in determining the styling of elements on a webpage. However, it's important to note that pseudo-classes like :not()
and the :nth-*()
family should not be viewed as filters. Rather, they serve as conditions or descriptors that an element must meet for styles to be applied.
Each simple selector within a sequence does not operate independently but rather collectively. The element must satisfy all specified conditions simultaneously for the styles to take effect. It's misleading to refer to CSS selectors as "filters" due to this nature.
For example, a selector specifying a tr
element within #element
that is not assigned the class isotope-hidden
and is the (2n+1)th child will only apply styles if all these criteria are met concurrently.
It's crucial to understand that CSS selectors do not function by sequentially filtering elements in the manner one might assume. Manipulating styles after applying filters is not feasible with CSS alone. Instead, jQuery's filter methods can be employed to achieve sequential filtering and subsequently apply styles based on the filtered results:
$('#element tr').not('.isotope-hidden').filter(':even');
An alternative approach using jQuery's filter selectors allows for concise selection of elements based on predetermined criteria:
$('#element tr:not(.isotope-hidden):even');
Despite the syntactical similarities between CSS selectors and jQuery filters, it's essential to recognize the fundamental distinctions outlined in various resources for precise usage and understanding of each.
