1.看了《学习CSS布局》，收获不小。以后可以把这个教程和w3cshool的css教程结合起来复习，当作工具书。

2.float布局，注意clear的使用。inline-block布局，多考虑。fixed和absolute。。。。

3.博客相册页面函数的代码尾端如下：

bucket = Bucket('hugstore')bucketr = Bucket('thumbnail')bucket.put()UrlList = [(bucket.generate_url(i['name']),bucketr.generate_url(i['name']),str(bucket.stat_object(i['name']).get('last_modified'))[:10]) for i in bucket.list()]   # 获取的图片地址，哈哈哈哈return render_template('album.html',UrlList = UrlList)

相对应的html模版为：

{% for (url,urlr,uptime) in UrlList %}<div class="album "><div class="albumimg"><img src={{urlr}}></div><div style="clear:both;"></div><a href={{url}}>原图</a>上传时间：{{uptime}}<!--{{uptime}}--></div>{% endfor %}

结果总是报错：

我可是严格审查了的啊。三个值的元组，列表解析。然后解包。没问题啊！！
