Part-3 | 23 - Advanced CSS Selector Priority | Complete Course for Web Development |
In CSS, the priority of a selector determines which style rules will be applied to an element when there are multiple conflicting rules. There are several factors that can affect the priority of a selector, including the specificity of the selector, the order of the style rules, and the source of the style rules.
Specificity: The specificity of a selector is a measure of how closely it matches an element in the HTML. Selectors that are more specific have a higher priority than those that are less specific. For example, an ID selector (#myid) is more specific than a class selector (.myclass), which is more specific than a type selector (div).
Order: When there are multiple style rules that apply to the same element, the rule that appears last in the stylesheet has a higher priority. This is known as the cascade.
Source: Style rules that are defined in an external stylesheet have a higher priority than those that are defined in an inline style attribute.
Here's an example of how these factors can affect the priority of a selector:
In this example, the div element will be green, because the last rule has a higher priority due to its position in the stylesheet.
