Css div box不随高度增长

当有更多内容出现时，蓝框和白div不扩展会有什么问题

我已经把CSS的领域，我的工作，但它不可能是问题

我希望盒子的高度与盒子外扩展的交易类别相同

CSS:

.content_inner{
    height: auto;
    background-color: #6c93b8;
    margin:12px;
    -moz-border-radius:5px;
    -webkit-border-radius:5px;
    border-radius:5px;
    clear:both;
}

.homeWrapper{
    padding: 12px;
    width:auto;
background-image: linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);
background-image: -o-linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);
background-image: -moz-linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);
background-image: -webkit-linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);
background-image: -ms-linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);

background-image: -webkit-gradient(
    linear,
    left bottom,
    left top,
    color-stop(0.73, rgb(71,95,124)),
    color-stop(0.85, rgb(33,50,86))
);

.leftColBlog{
    display: inline-block;
    width:650px;
    margin:0 0 5px 0;
    background-color: #fff;
}
.rightColBlog{
    display: inline-block;
    float: right;
    width:230px;
    text-align: left;
}

问题：

.content_inner{
    height: auto;
    background-color: #6c93b8;
    margin:12px;
    -moz-border-radius:5px;
    -webkit-border-radius:5px;
    border-radius:5px;
    clear:both;
}

.homeWrapper{
    padding: 12px;
    width:auto;
background-image: linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);
background-image: -o-linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);
background-image: -moz-linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);
background-image: -webkit-linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);
background-image: -ms-linear-gradient(bottom, rgb(71,95,124) 73%, rgb(33,50,86) 85%);

background-image: -webkit-gradient(
    linear,
    left bottom,
    left top,
    color-stop(0.73, rgb(71,95,124)),
    color-stop(0.85, rgb(33,50,86))
);

.leftColBlog{
    display: inline-block;
    width:650px;
    margin:0 0 5px 0;
    background-color: #fff;
}
.rightColBlog{
    display: inline-block;
    float: right;
    width:230px;
    text-align: left;
}

一种方法是添加

溢出：隐藏到
.homebrapper
和
.content\u inner

这将为右侧菜单创建一个新的块格式上下文，因为浮动的元素将从正常流中取出，需要清除，或者需要一个溢出值不是其他元素可见的容器
