html 8f0e1a3c54056efb6030e652a6462cafTag definition and usage

Comment tags are used to insert in source code Note. Comments will not be displayed in the browser.

You can use comments to explain your code, which will help you edit the code at a later time. Especially useful when you write a lot of code.

It is also a good practice to use comment tags to hide scripts that are not supported by the browser (so that the script is not displayed as plain text):

<script type="text/javascript">
<!--
function displayMsg()
{
alert("Hello World!")
}
//-->
</script>

Comment: two lines at the end of the comment line The slash (//) is the JavaScript comment symbol. This prevents JavaScript from executing the --> tag.

<!--这是一段注释。注释不会在浏览器中显示。-->

<p>这是一段普通的段落。</p>
