What is the weight of pseudo elements?

The weight of pseudo elements is 0. In CSS, selector weight is used to determine the priority of styles. The higher the weight value, the higher the priority and the style will be applied. This means that no matter where the pseudo-element selector appears in the selector, it has the lowest weight. Even when combined with other selectors, the weight of a pseudo-element selector does not affect the weight of the entire selector. No matter what the weight of other selectors is, the styles of pseudo-element selectors will not be overridden, etc.

The weight of pseudo elements is 0. In CSS, selector weight is used to determine the priority of styles. The higher the weight value, the higher the priority and the style will be applied. In the calculation of weight, the weight of element selectors is higher than that of pseudo-element selectors.

Pseudo elements are used to apply styles to specific parts of elements. They are represented by using double colons (::) in selectors, such as "::before" and "::after" etc. Unlike pseudo-classes, pseudo-element selectors can only select specific parts of an element, not the element itself.

In CSS weight calculation, the weight of the pseudo-element selector is 0. This means that no matter where the pseudo-element selector appears in the selector, it has the lowest weight. Even when combined with other selectors, the weight of a pseudo-element selector does not affect the weight of the entire selector.

For example, consider the following CSS rule:

p::before {
  content: "Before";
  font-weight: bold;
}

In this rule, the selector "p::before" is used to select the front part of all paragraph elements and set the content to "Before " and make the font bold.

However, the weight of the pseudo-element selector "::before" is always 0, no matter how other selectors are combined. This means that the styles of pseudo-element selectors will not be overridden, regardless of the weight of other selectors.

In summary, the weight of pseudo elements is 0. They cannot use weights to increase the priority of styles. If you need to change the style of a pseudo-element, you can use other methods, such as more specific selectors, !important declarations, or adding inline styles.
