CSS注释不会在浏览器中显示,但可以 帮助记录您的源代码。
注释用于解释代码,并且可能会在您以后编辑源代码时有所帮助。
浏览器会忽略注释。
CSS 注释位于 <style>
元素内,以 /*
开头,以 */
:
/* This is a single-line comment */
p
{
color: red;
}
自己尝试一下→
<!DOCTYPE html>
<html>
<head>
<style>
/* This is a single-line comment */
p {
color: red;
}
</style>
</head>
<body>
<p>Hello World!</p>
<p>This paragraph is styled with CSS.</p>
<p>CSS comments are not shown in the output.</p>
</body>
</html>
您可以在代码中任意位置添加注释:
p
{
color: red;
/* Set text color to red */
}
自己尝试一下 →
<!DOCTYPE html>
<html>
<head>
<style>
p {
color: red; /* Set text color to red */
}
</style>
</head>
<body>
<p>Hello World!</p>
<p>This paragraph is styled with CSS.</p>
<p>CSS comments are not shown in the output.</p>
</body>
</html>
评论也可以跨越 多行:
/* This is
a multi-line
comment */
p
{
color: red;
}
自己尝试一下→
<!DOCTYPE html>
<html>
<head>
<style>
/* This is
a multi-line
comment */
p {
color: red;
}
</style>
</head>
<body>
<p>Hello World!</p>
<p>This paragraph is styled with CSS.</p>
<p>CSS comments are not shown in the output.</p>
</body>
</html>
从 HTML 教程中,您了解到可以使用以下命令向 HTML 源添加注释 语法。
在以下示例中,我们结合使用 HTML 和 CSS 注释:
<!DOCTYPE html>
<html>
<head>
<style>
p {
color: red; /* Set
text color to red */
}
</style>
</head>
<body>
<h2>My
Heading</h2>
<!-- These paragraphs will be red -->
<p>Hello
World!</p>
<p>This paragraph is styled with CSS.</p>
<p>CSS comments are
not shown in the output.</p>
</body>
</html>
自己尝试一下 →
<!DOCTYPE html>
<html>
<head>
<style>
p {
color: red; /* Set text color to red */
}
</style>
</head>
<body>
<h2>My Heading</h2>
<!-- These paragraphs will be red -->
<p>Hello World!</p>
<p>This paragraph is styled with CSS.</p>
<p>HTML and CSS comments are not shown in the output.</p>
</body>
</html>
