请尽量使用JQuery进行代码编写，需求如下：
1. 页面初始化样式如图
2. 顶部input框中输入内容，按下回车enter键后，“正在进行” 列表中加入该条内容。
3. 顶部input框中输入内容，按下回车enter键后，“正在进行” 列表中继续加入内容。右上角的数字跟随列表数目变化而变化。
4. 点击列表左侧checkbox，可以将“正在进行”的列表项变更为“已经完成”的列表项。每个列表中的数字要跟随变动。
5. 点击列表项右侧的删除按钮可以删除列表项。
6. 将当前列表项内容保存在cookie中，做持久存储，下一次访问页面的时候，仍可以看到以前的列表项内容。
7. 要求样式布局尽量和图片上保持一致
