How do CSS selectors (e.g., class, ID, attribute, pseudo-class, pseudo-element) target HTML elements?
Article Introduction:CSS selectors apply styles by matching elements in HTML structures. The main types include class selectors, ID selectors, attribute selectors, pseudo-classes and pseudo-elements. 1. The class selector starts with a dot (.) to match any element with a specific class name, which can be used in combination with the element type and avoid general naming; 2. The ID selector starts with a pound sign (#) to match the unique element in the page, and should be used with high priority with caution; 3. The attribute selector matches based on HTML attributes and their values, suitable for form or link filtering; 4. The pseudo-class starts with a colon (:) and applies styles according to the element status or location, such as:hover, :focus, etc.; 5. The pseudo-element starts with a double colon (::) and is used to modify part of the element's content or add the generated content.
