如何剪切这两个div之间的共享边界线？我希望顶部的小div有三边的边框,预计底部和下面的larder div只有顶边但留下共享边框.因此它看起来像一条横跨两个div上边界的线.我尝试在底部覆盖顶部div.但没有得到我想要的.

 .ihead {
background-color: #EEE;
width: 15em;
height: 3em;
text-align:center center;
border-top:1px solid black;
border-left:1px solid black;
border-right:1px solid black;
border-bottom:none;

  }

    .ibody {
background-color: #EEE;
width: 60em;
height:20em;
margin-top:3em;
border-top:1px solid black;
z-index: 10;

  }


<div class="ihead"><h>Hello !</h></div>
<div class="ibody">......</div>

如何在列表项空间的底部浮动文本？我试图让 li 中的所有文本都位于 li 高度的底部。有没有更好的方法来实现这种外观？以及如何超链接 h1 标头？

  margin: 0;

nav {
  width: 100%;

.menu ul {

  margin-top: 110px;

我用rvm gem install bundler安装了bundler.这里有什么问题？

还用这些选项重新安装 -

apt-get install libncurses5-dev libreadline5-dev libreadline-dev librequire-dev
rvm use ruby-1.9.3-p125 --default
rvm reinstall librequire-dev libbundler-dev --with-readline-dir=/usr/include/readline

我正在尝试创建一个小的搜索表单来搜索ldap中的用户.它与本地数据模型没有任何关系.不确定为什么我需要在用户控制器中进行任何更改.这个错误并没有给我任何线索.

模型 - 在ldap中搜索的函数

如何在VARCHAR中插入带有空格的字符串？

insert into users (user_id,firstname,lastname,email,group) values('admin','some','Body','admin@something.com','Site admin');

这给了我语法错误,我是mysql的新手,我浏览了mysql文档,并没有让我清楚地知道为什么会出现这种情况.

 mysql> insert into users (user_id,firstname,lastname,email,group) values('admin','some','Body','admin@something.com','Site admin');
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'group) values('admin','some','Body','admin@something.com','Site admin')' at line 1
