How to Apply Alternating Colors to List Items with the 'Parent' Class Using nth-child Selector?

Nth-Child Selector with Class: Overcoming Resetting Colors

In an attempt to apply alternating colors to list items with the "parent" class, you might have encountered the issue of colors resetting after certain non-matching elements. This issue arises due to the limitations of the :nth-child selector.

However, a workaround exists using the general sibling combinator (~). By defining rules for elements following non-matching ones, you can toggle the colors for subsequent matching elements. Here's how:

.parent:nth-child(odd) {
    background-color: green;
}
.parent:nth-child(even) {
    background-color: red;
}

/* Toggle colors after first non-parent element */
li:not(.parent) ~ .parent:nth-child(odd) {
    background-color: red;
}
li:not(.parent) ~ .parent:nth-child(even) {
    background-color: green;
}

/* Toggle colors again after second non-parent element */
li:not(.parent) ~ li:not(.parent) ~ .parent:nth-child(odd) {
    background-color: green;
}
li:not(.parent) ~ li:not(.parent) ~ .parent:nth-child(even) {
    background-color: red;
}

With this approach, each :not(.parent) element serves as a "reset" point, toggling the colors of последующие соответствующие элементы. Although it has limitations in terms of how far it can extend, it's the closest approximation to alternating colors using pure CSS.
