HTML、CSS和JS中注释类型的总结_html/css_WEB-ITnose
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
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-->
2、CSS注释
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; }
3、JavaScript注释
块级注释:/*注释的内容*/;
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";
