Why are My Alternating Colors Resetting When Using :nth-child(even/odd) with a Class?

:nth-child(even/odd) Selector with Class Issue

You aim to apply alternating colors to list items with the "parent" class. However, you encounter problems with the colors resetting. To resolve this, consider the following:

Solution:

Since CSS rules are applied top-to-bottom, the :nth-child(even/odd) selectors will potentially override previous color settings. To address this, use the general sibling combinator (~) to toggle colors after non-"parent" elements:

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

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

Explanation:

• The first two rules set the alternating colors for "parent" elements.
• Subsequent rules use the ~ combinator to toggle colors after non-"parent" elements.
• Each set of rules alternates the colors with increased specificity, ensuring the desired behavior.

Limitations:

While this method allows you to achieve alternating colors for a limited number of non-"parent" elements, there is a limit to how far you can extend this approach.
