css comment html

CSS comments are a way to add instructions to your stylesheet. In CSS, comments are text that is not rendered by the browser; it is just a way to identify the code.

The syntax of CSS comments is simple, it starts with / and ends with /. All text between these two symbols will be treated as comments. Here is an example:

/* 这是一个 CSS 注释 */
body {
  background-color: #fff;
}

In the above example, since the comment line starts with /*, all text on that line will be treated as a comment. Comments are ignored when the browser renders this stylesheet.

CSS comments are very useful because they help developers better organize and manage their code. For example, comments can be used to record special features in the code, identify code blocks, remind developers to update the code, etc.

Here are some common uses of CSS comments:

1. Describe the purpose of a style sheet or code block:

/*
  这个样式表用于定义网站主页的布局和样式。
*/

/*
  下面的代码块将定义页面顶部的导航栏部分。
*/
.nav {
  /* 导航栏样式定义 */
}

2. Identify the purpose of a stylesheet or code block: Special features:

/*
  这段代码用于添加页面过渡效果。
*/
.transition {
  /* 过渡效果样式定义 */
}

3. Remind developers to update code:

/*
  这个代码块需要优化，以减少页面加载时间。
*/

When writing CSS code, we should use comments to record our code as much as possible , which not only makes the code more organized, but also allows for better collaboration with the team. Comments allow new members to quickly understand the purpose and function of the code and join development faster.
