How to write comments in html? What are the comment symbols in html? (with examples)

This article mainly introduces the comment symbols in HTML, how to write comment symbols and the example analysis of comment symbols. Next, let us look at this article together

First of all What we need to know is what are the comment symbols in html?

Comment tags are used to insert comments in source code. 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)

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

This is an example of comments:

<!-- 这是一段注释 -->
<p>这是一个段落。PHP中文网</p>
<!-- 记得在此处添加信息 -->

There is no need to look at the renderings for this example. Obviously, this will only be displayed in the browser as < The content in the ;p> tag and the other two lines will not be displayed at all, because this is for others to see and will not be recognized by the browser.

Another bonus: comments are also helpful for HTML debugging, because you can comment out one line of HTML code at a time to search for errors:

Here are also examples of comments:

<!-- 此刻不显示图片：
<img src="/static/imghwm/default1.png"  data-src="/i/tulip_ballade.jpg"  class="lazy"  border="0"  alt="Tulip">
-->

Conditional comments define HTML tags that only Internet Explorer executes .
