添加必要的注释,是一个优秀的程序员必须具备的好习惯,可以大大提高代码的可维护性、可读性。

1、HTML注释

  • 注释的地方(根据个人习惯可能有所不同):
  •   结束标签的后面,这一切都是为了程序在嵌套的时候更加方便、明了,如:     

    <div class="main"></div><!--注释的内容-->
    Copy after login

    2、CSS注释

  • /*注释的内容*/
  • 注释的位置:
  •   某个模块样式开始的地方,说明这段样式是作用于哪段模块,如:

    /*header*/header {     width: 800px;     background-color: #999;  }/*footer*/footer {     width: 800px;     background-color: #EEE;  }
    Copy after login

    3、JavaScript注释

  • 单行注释://注释的内容;
  •    块级注释:/*注释的内容*/;

  • 注释位置:
  •    一般将注释添加在某段功能函数的上边,说明函数的功能、作者、作者信息、修改时间。如:

    // 输出标题:document.getElementById("myH1").innerHTML="Welcome to my Homepage";
    Copy after login
