How to connect css and html

WBOYOriginal: 2023-05-29 18:30:385460browse

HTML and CSS are two basic skills for web development. HTML is used to build the structure of web pages, while CSS is used to beautify the appearance of web pages. Whether you're an experienced web developer or a beginner, you need to know how to combine these two skills to create truly great web pages.

1. Use internal CSS

In the head tag of an HTML page, you can embed CSS styles through the c9ccee2e6ea535a969eb3f532ad9fe89 tag. You can define all the CSS styles you need in the c9ccee2e6ea535a969eb3f532ad9fe89 tag, so that the HTML page will apply the CSS styles to the document when it loads. For example, the following example:

<!DOCTYPE html>
<html>
<head>
    <title>我的网页</title>
    <style>
        body {
            background-color: blue;
        }
        h1 {
            color: white;
            text-align: center;
        }
    </style>
</head>
<body>
    <h1>欢迎来到我的网页</h1>
    <p>这是我的第一个网页</p>
</body>
</html>

In the above code, we set the page background color to blue and the title color by embedding CSS styles in the c9ccee2e6ea535a969eb3f532ad9fe89 tag Be white and center aligned.

2. Use external CSS files

If you want to use the same CSS style in multiple HTML pages, then using internal CSS will be very redundant. At this time we can use external CSS document. We create a new file with the .css suffix, such as style.css, and link the CSS style file to the page through the 2cdf5bf648cf2f33323966d7f58a7f3f tag in the head tag of the HTML page. For example:

<!DOCTYPE html>
<html>
<head>
    <title>我的网页</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <h1>欢迎来到我的网页</h1>
    <p>这是我的第一个网页</p>
</body>
</html>

In the style file style.css, we can define all the CSS styles we need to use.

body {
    background-color: blue;
}
h1 {
    color: white;
    text-align: center;
}

3. Use inline CSS

In addition to internal CSS and external CSS files, we can also use inline CSS. Inline CSS refers to using the style attribute within HTML tags to define CSS styles. For example:

<!DOCTYPE html>
<html>
<head>
    <title>我的网页</title>
</head>
<body>
    <h1 style="color: white; text-align: center;">欢迎来到我的网页</h1>
    <p style="background-color: blue;">这是我的第一个网页</p>
</body>
</html>

In the above code, we use the style attribute in the 4a249f0d628e2318394fd9b75b4636b1 tag and the e388a4556c0f65e1904146cc1a846bee tag to define the title respectively color and alignment, as well as the background color of the paragraph.

Summary

Whether it is internal CSS, external CSS files or inline CSS, their ultimate purpose is to beautify the appearance of the web page. In actual development, we can choose different ways to link CSS and HTML according to the actual situation. When there are more CSS styles to be defined, we can use external CSS files; when there are fewer styles to be defined, we can use internal CSS or inline CSS.
