想象一下下面的布局,其中圆点代表盒子之间的空间:

[Left box]......[Center box]......[Right box]

当我移除右边的方框时,我希望中间的方框仍然在中间,就像这样:

[Left box]......[Center box].................

如果我移除左边的方框也是一样的。

................[Center box].................

现在,当中心框中的内容变长时,它将根据需要占用尽可能多的可用空间,同时保持居中。左右方框永远不会缩小,因此当没有空格时,overflow:hidden和text-overflow:省略号将生效,破坏内容;

[Left box][Center boxxxxxxxxxxxxx][Right box]

以上都是我的理想情况,但是我不知道如何达到这个效果。因为当我创建一个这样的伸缩结构时:

.parent {
    display : flex; // flex box
    justify-content : space-between; // horizontal alignment
    align-content   : center; // vertical alignment
}

如果左右方框的大小完全相同,我就会得到想要的效果。然而,当其中一个的大小不同时,居中的盒子就不再是真正的居中。

有人能帮我吗?

一个自我证明很好,这很理想

.leftBox {
     justify-self : flex-start;
}

.rightBox {
    justify-self : flex-end;
}

我想要在问题中显示的确切结果,我结合了gamliela和Erik Martín Jordán的答案,它最适合我。

.parent {
    display: flex;
    justify-content: space-between;
}

.left, .right {
   flex-grow: 1;
   flex-basis: 0;
}

.right {
   display: flex;
   justify-content: flex-end;
}

其他回答

这里有另一种方法,在父元素和子元素中使用display: flex:

.Layout { 显示:flex; justify-content:中心; } .Left { 显示:flex; justify-content: flex-start; 宽度:100%; } 铃声{ 显示:flex; justify-content: flex-end; 宽度:100%; } <div class = 'Layout'> <div class = 'Left'>我在左边</div> <div class = 'Mid'>居中</div> <div class = 'Right'>我在右边</div> < / div >

虽然我在这个问题上可能晚了,但所有这些解决方案似乎都很复杂,而且根据你所面临的情况可能不会起作用。

非常简单,只需要用position: absolute来包装你想要居中的组件,而让其他两个组件用justify-content: space来分隔,如下所示:

CSS:

.container { display: flex; justify-content: space-between; align-items: center; background-color: lightgray; } .middle { position: absolute; margin-left: auto; margin-right: auto; /* You should adapt percentages here if you have a background ; else, left: 0 and right: 0 should do the trick */ left: 40%; right: 40%; text-align: center; } /* non-essential, copied from @Brian Morearty answer */ .element { border: 1px solid #ccc; background-color: lightgreen; } p { margin: 5px; padding: 5px; } <div class="container"> <p class="element">First block</p> <p class="middle element">Middle block</p> <p class="element">Third THICC blockkkkkkkkk</p> </div>

你可以这样做:

.bar { display: flex; background: #B0BEC5; } .l { width: 50%; flex-shrink: 1; display: flex; } .l-content { background: #9C27B0; } .m { flex-shrink: 0; } .m-content { text-align: center; background: #2196F3; } .r { width: 50%; flex-shrink: 1; display: flex; flex-direction: row-reverse; } .r-content { background: #E91E63; } <div class="bar"> <div class="l"> <div class="l-content">This is really long content. More content. So much content.</div> </div> <div class="m"> <div class="m-content">This will always be in the center.</div> </div> <div class="r"> <div class="r-content">This is short.</div> </div> </div>

Michael Benjamin给出了一个不错的答案,但没有理由不能/不应该进一步简化:

.container {
  display: flex;
}

.box {
  flex: 1;
  display: flex;
  justify-content: center;
}

.box:first-child { justify-content: left; }

.box:last-child  { justify-content: right;  }

和html

<div class="container">
  <div class="box">short text</div>
  <div class="box">centered tex</div>
  <div class="box">loooooooooooooooong text</div>
</div>

Use three flex items in the container Set flex: 1 to the first and last ones. This makes them grow equally to fill the available space left by the middle one. Thus, the middle one will tend to be centered. However, if the first or last item has a wide content, that flex item will also grow due to the new min-width: auto initial value. Note Chrome doesn't seem to implement this properly. However, you can set min-width to -webkit-max-content or -webkit-min-content and it will work too. Only in that case the middle element will be pushed out of the center.

.outer-wrapper { display: flex; } .item { background: lime; margin: 5px; } .left.inner-wrapper, .right.inner-wrapper { flex: 1; display: flex; min-width: -webkit-min-content; /* Workaround to Chrome bug */ } .right.inner-wrapper { justify-content: flex-end; } .animate { animation: anim 5s infinite alternate; } @keyframes anim { from { min-width: 0 } to { min-width: 100vw; } } <div class="outer-wrapper"> <div class="left inner-wrapper"> <div class="item animate">Left</div> </div> <div class="center inner-wrapper"> <div class="item">Center</div> </div> <div class="right inner-wrapper"> <div class="item">Right</div> </div> </div> <!-- Analogous to above --> <div class="outer-wrapper"><div class="left inner-wrapper"><div class="item">Left</div></div><div class="center inner-wrapper"><div class="item animate">Center</div></div><div class="right inner-wrapper"><div class="item">Right</div></div></div><div class="outer-wrapper"><div class="left inner-wrapper"><div class="item">Left</div></div><div class="center inner-wrapper"><div class="item">Center</div></div><div class="right inner-wrapper"><div class="item animate">Right</div></div></div>
