无法使用最大宽度设置居中复杂内容

时间：2016-12-01 17:44:28

标签： html css

我的中心内容有max-width元素集我有问题。左右的间距不一样。 This is a pen to my project。问题似乎源于形式 side-post, span_1_of_3，因为右边的可变边距。

我试过

 .inner {
        display: table;
        margin: 0 auto;
    }

 .outer2{
    margin: 0 auto;
    display: table;
    text-align:center;
    }

我对这个问题的解决方案有点困惑。任何想法如何解决？

删除宽度：15em;来自.side-post和间距将相等

你可以使用display：flex on .outer2和justify-content：center和align-items：center，它应该集中你所有的内容

答案 2 :(得分：0)

更改边帖的CSS。您的边距设置正确但side_post具有固定的宽度。它应该是100％。

旧CSS 

.side-post {
    background: #fff;
    margin: 0 auto 1.5em auto;
    width: 15em;
    padding: 20px;
}

新CSS 

.side-post {
    background: #fff;
    /* margin: 0 auto 1.5em auto; */
    width: 100%;
    padding: 20px;
    box-sizing: border-box;
}
