Which statement best captures the main point of this lesson?
Complete the missing token from the example code.
/* ___ is a single-line comment */Put the learning moves in the order that makes the concept easiest to apply.
Comments are used to explain the CSS code, and may help when you edit the source code at a later date.
Comments are also used to temporarily disable sections of CSS code within a stylesheet.
Comments are ignored by browsers!
A CSS comment is placed inside the HTML <style> element, and starts with /* and ends with */ :
Example
/* This is a single-line comment */
p {
color: red;
}Live preview
You can add comments wherever you want in the code:
Example
p {
color: red;
/* Set text color to red */
}Live preview
Even in the middle of a code line:
Example
p {
color: /*red*/blue;
}Live preview
Example
/* This is
a multi-line
comment */
p {
color: red;
}Live preview
HTML and CSS Comments
From the HTML tutorial, you learned that you can add comments to your HTML source by using the <!--...--> syntax.
In the following example, we use a combination of HTML and CSS comments:
Example
<!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>Live preview
