"CSS与HTML结合的三种方法"

Summary: This passage discusses three methods of combining CSS and HTML: inline style sheets, internal style sheets, and external style sheets. The first method, inline style sheets, involves adding style directly to the HTML elements using the "style" attribute. This method is not commonly used as it doesn't fully leverage the advantages of style sheets in separating content structure and style control. The next method, internal style sheets, involves adding CSS code within the HTML document using the "style" tag. This allows for greater control over the style of multiple elements within a single document. However, this method is still limited as it affects only the specific HTML document in which the CSS code is embedded. The third and most widely used method is external style sheets. This involves creating a separate CSS file and linking it to the HTML document using the "link" tag. This allows for a centralized and modular approach to style management, as the same CSS file can be linked to multiple HTML documents. Any changes made to the external style sheet will be reflected across all linked HTML documents, making it efficient for managing consistent styles across a website. Overall, the use of CSS in combination with HTML provides greater flexibility and control over the visual presentation of web content. By separating the style information from the HTML structure, it becomes easier to maintain and update the design of a website. The three methods discussed provide different levels of control and flexibility, allowing web developers to choose the best approach based on their specific requirements.
