You can connect an external CSS file to an HTML5 document by using the tag in the <head> section of the HTML document: Create a CSS file with a .css extension, such as styles.css.

How to use HTML5 to connect CSS
Introduction:
CSS (Cascading Style Sheets) is used to add style and layout to HTML documents. In order to use CSS, it needs to be concatenated into an HTML file. This article explains how to connect CSS in HTML5.
Steps:
-
Create a CSS file:
Use a text editor to create a new CSS file, usually ending with.css
is the extension. For example,styles.css
. -
Reference a CSS file in an HTML document:
Within the<head>
section of the HTML document, use<link>## The # tag references a CSS file. The
<head>section is located at the top of the document, before the
tag.
<head> <title>我的頁(yè)面</title> <link rel="stylesheet" href="styles.css"> </head>
- Writing styles in CSS files: In CSS files, use CSS rules to add styles to HTML elements. CSS rules consist of selectors and declaration blocks. The selector specifies the HTML element to apply the style to, and the declaration block specifies the style attribute to apply.
body { font-family: Arial, sans-serif; font-size: 16px; }
Tip:
- Place the CSS file in the same directory as the HTML document to ensure proper linking.
- You can reference multiple CSS files by adding additional
tags in the
<head>section.
Using external CSS files can make HTML documents easier to maintain because the styles are saved in a separate file.

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

The usage steps include installing plug-ins, setting browserslist, and enabling them in the build process; 4.

The scope of CSS custom properties depends on the context of their declaration, global variables are usually defined in :root, while local variables are defined within a specific selector for componentization and isolation of styles. For example, variables defined in the .card class are only available for elements that match the class and their children. Best practices include: 1. Use: root to define global variables such as topic color; 2. Define local variables inside the component to implement encapsulation; 3. Avoid repeatedly declaring the same variable; 4. Pay attention to the coverage problems that may be caused by selector specificity. Additionally, CSS variables are case sensitive and should be defined before use to avoid errors. If the variable is undefined or the reference fails, the fallback value or default value initial will be used. Debug can be done through the browser developer

There are three ways to create a CSS loading rotator: 1. Use the basic rotator of borders to achieve simple animation through HTML and CSS; 2. Use a custom rotator of multiple points to achieve the jump effect through different delay times; 3. Add a rotator in the button and switch classes through JavaScript to display the loading status. Each approach emphasizes the importance of design details such as color, size, accessibility and performance optimization to enhance the user experience.

CSS's :target pseudo-class is used to style the target element based on the URL fragment identifier. It works by the browser scrolling to the element when the URL contains a # symbol and element id and allows a specific style to be applied to the element via :target. Common use cases include highlighting the page section after navigation, creating tabs or slideshows without JavaScript, and improving accessibility to long pages. Usage tips include ensuring that id is unique, combining transition or animation effects, switching content visibility with display attributes, and considering compatibility with older browsers.
