How Can I Exclude the First Element Using CSS Selectors?

Excluding the First Element with the CSS :not:first-child Selector

In CSS, the :first-child selector targets the first child element of its parent element. To exclude the first element, you can use the inverse selector :not:first-child.

Attempt 1: Using :not:first-child

div ul:not:first-child {
    background-color: #900;
}

Attempt 2: Using :not(:first-child)

div ul:not(:first-child) {
    background-color: #900;
}

Attempt 3: Using :first-child:after

div ul:first-child:after {
    background-color: #900;
}

However, none of these methods achieved the desired result.

Solution: Using Browser Compatibility Fix

The :not selector only accepts a simple selector as its argument. Therefore, to support legacy browsers that do not support the :not(:first-child) syntax, you can employ an alternative technique:

1. Define a rule with a broader scope than intended:

div ul {
    background-color: #900;
}

2. "Revoke" the rule conditionally to limit its scope to the excluded element:

div ul:first-child {
    background-color: transparent;
}

Explanation:

The first rule applies the background color to all ul elements. The second rule uses the default value (transparent) for background-color, effectively removing the background color from the first child ul element.
