个人总结：前端其实是第一次接触，说实话很迷不知道***才能能把页面做的和***，以前是分不清HTML和CSS的作用的，现在我知道到了，HTML可以创造一个个页面元素，然后通过CSS去选择对应的元素加工，描述，在用HTML+CSS对页面进行布局的时候，挺抽象的，不像以前玩魔兽地图编辑器一样，可以拖动组件，然后设置属性就好，它需要从上到下先把你需要的元素通过html先写出来，然后在通过CSS去调整它的位置，样式，达到具体想要的效果；

常用的CSS属性记得比较容易记得住，但是一些不常用通过看手册知道有这个功能可是目前只能是想用到就去查手册，多练习才能记得

在做商品推荐区的时候我在想可不可以用表格来做，因为表格有个单元格与单元格之间的距离这个属性，能很好的让展示框与展示框之间进行隔开，在一个单元格里在填充想要的元素组件，此时元素组件的定位就是相对于单元格了，那么只要控制好块元素和内联元素的属性通过内外边距来挤位置，可以很容易做好样式的定位，先写规定好一个单元格内的需要什么元素，在复制成一列4个排列，调整好样式距离，然后按单元格元素格式直接增加行列就好了。也不知这样写是好还是不好，上课时记得老师说，前端是八仙过海，各显神通，于是就试一下。

作为前端的新手，代码有些地方还写得很乱，一些是原生属性，一些又直接写在标签里！这些以后要多注意，最后前端真是个抽象的东西需要多加练习才行。

Teacher's comments：用表格制作商品展示, 不如作嵌套的无序列表, 当然, 表格也非常适合的还有, 你的购买按钮是真的丑
