第2天 html标签及属性

一、标签分类

单标签：内容一般由外部引入
双标签：内容在标签之间
不同类型的标签，属性不同

二、作业：作业内容：写一个商品信息表，要求有id,品名，价格，数量，金额等字段，最后要有合计，如总数，总金额，并且商品按品类进行合并显示，要求用到行与列的合并，别怕失败，多写几次，就对表格的编写就熟练了。
浏览器显示效果：

html代码如下：

<!DOCTYPE html>
<html lang="zh-ch">

    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
