我认为写HTML结构最重要的是分清每个板块间的位置关系，然后每个板块里面的内容开始之前，就要想好里面的标签之间的写法，如判断是否要加ul,li,a标签里面是否有图片，a标签里的文字是否要添加其他样式等等。思路要清晰。
例子如图分析首先要一个大的div包裹，设置宽高和边框，然后由于有图片等，肯定会改变它们的位置关系，因此设置position:relative（子绝父相）；而且一定居中，设line-height。其次，里面内容分4大块，左边图片，中间文字，右边>号，上面不规则图形，然后图片和文字有链接，可以这样写HTMLhttp://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/>；http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/0http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/http://img.gxlcms.com//Uploads-s/new/2019-09-27-201927/我的购物车
