CSS :not() Selector

CSS The :not() selector is used to select elements that do not meet a specified condition. Its syntax is as follows:

:not(selector) {
/* CSS rules */
}

Where selector is any valid CSS selector, it is used to select elements that meet the conditions. However, it is important to note that the :not() selector can only accept a simple selector as a parameter and cannot contain complex selectors.

CSS Nesting

In CSS, nested selectors allow us to nest selectors within another selector for more convenient element selection. Through CSS nesting, we can avoid duplicating certain styles and improve code readability.

Using CSS nesting with the :not() selector, we can achieve more flexible element selection methods. Here’s an example code:

div:not(.container) {
background-color: red;

p {
font-size: 16px;

}
}

In the example above, we select all div elements without the .container class and set their background color to red. We also use a nested selector to select all p elements within those div elements and set their font size to 16 pixels.

Example Description

Below, we’ll use some specific examples to illustrate how to use CSS nesting within the CSS :not() selector.

Example 1: Selecting Elements Without a Specific Class

div:not(.container) {
/* CSS rules */ 
}

The above code will select all div elements without the .container class and apply the corresponding CSS styles.

Example 2: Selecting elements without a specific attribute

a:not([href]) {
/* CSS rules */ 
} 

The above code selects all a elements without an href attribute and applies the corresponding CSS styles.

Example 3: Selecting Elements Without a Specific Child

li:not(:has(a)) { 
/* CSS rules */ 
} 

The above code selects all li elements without a child a and applies the corresponding CSS styles.

Summary

The CSS :not() selector and CSS nesting provide more flexibility in selecting and styling elements. Through some examples, we’ve learned how to use the :not() selector and CSS nesting to select elements under specific conditions and apply corresponding styles. We hope this article will help you use the :not() selector and CSS nesting in CSS.
