上有margin: 0 auto;
,它仍然没有居中。是因为它没有固定宽度吗?它没有固定的宽度,因为我希望.detailedBox
是所有.detailedBox
组合的宽度,但也是居中的。
答案 0 :(得分:1)
如果您将display: flex
更改为justify-content: center
(而不是内嵌块),然后执行{{1}},那么它会将该div水平居中。
答案 1 :(得分:0)
由于.detailBox
设置为inline-block
,因此无法使用margin:0 auto
将其居中。理解这一点的一种方法是“边缘居中”技术依赖于“填充”可用的水平空间。但是在使用内联元素时没有可用空间。 (参考:margin:auto; with inline-block。)
另请注意:
10.3.9'内联块',正常流程中未替换的元素
如果'width'为'auto',则使用的值是浮动元素的收缩宽度 'margin-left'或'margin-right'的计算值'auto'成为'0'的使用值 - w3.org
另一种方法是让.detailBox
默认为display:block
,并将text-align:center
设置为水平居中于.content
的子inline-block
元素。

您提到您希望.detailBox
为所有内容组合的宽度。因此,如果由于某种原因您需要.detailBox
保留inline-block
,则可以在它的父级text-align:center
上设置.holder
。像这样:
body {
background: #212121;
}
.wrapper {
height: 100%;
width: 100%;
overflow: hidden;
}
.holder {
height: 50%;
width: 100%;
position: absolute;
top: 25%;
left: 0%;
text-align:center;
}
.content {
height: 100%;
width: 100px;
margin: 10px;
display: inline-block;
background: #424242;
-webkit-box-shadow: 0px 1px 3px 0px rgba(0, 0, 0, 1);
-moz-box-shadow: 0px 1px 3px 0px rgba(0, 0, 0, 1);
box-shadow: 0px 1px 3px 0px rgba(0, 0, 0, 1);
}
.detailBox {
height: 100%;
display:inline-block;
font-size: 0;
