笔者发布此文的目的有三：
- 文章很美，留下痕迹
- 样式很美，是bootstrap
- 伊人很美，是群消息
查看完整效果，请新建一个txt文件，然后将实现源码内容复制进去，修改文件后缀名为x.html,用浏览器打开即可。

"detail":"<p>待我长发及腰，问君何处离殇。待我青丝馆正，伊人落泪为谁。时光远逝，回忆刺骨，此情已是绝期，你若忘，我必不殇。数落繁华，终是凄凉，穿梭昨日，往返徘徊，终是花开花谢，如季节，春去秋来不可逆违。花香满地，此刻只愿珍重，我已不是你当初所爱的男子。执着不过是痛，珍惜来日是福，你若安好，便是我最大幸福。</p>\
<p>一片至诚，寄情文字，不为半点修饰，仅不再打扰。天微亮，又是一天，铺上纸张，手提墨笔，挥手即是开始，思念婉转于眸，往事化作一笑，岁月定当点缀嫣然。心有所见，你...已是曾经。夜微凉，又过一天，唯有往事不悔，不弃来日。心有所见，心系当下，此刻便是幸福。</p>\
<p>昔日，你是我最好的初见，我是你最好的夙愿。许一世繁华，愿此生不分离。却无奈，无奈，此刻已成过往，心有牵挂，也已徒劳。道世事无常，时光残忍。只愿来世不再相见，如此便不相恋。唯借一缕清风，渡我伤心。今夜月圆，唯有默默祈祷，此刻幸福。</p>\
<p>梧桐雨，三更雨，不道离情正苦。我不怪世道无情，只怪相遇锦瑟年华。愿来日幸福，今日无悔。珍重......</p>"
