是否有比使用方法更灵活的“联系人”右对齐方式position: absolute

.main { display: flex; }
.a, .b, .c { background: #efefef; border: 1px solid #999; }
.b { flex: 1; text-align: center; }
.c { position: absolute; right: 0; }
<h2>With title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <div class="b"><a href="#">Some title centered</a></div>
    <div class="c"><a href="#">Contact</a></div>
</div>
<h2>Without title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <!--<div class="b"><a href="#">Some title centered</a></div>-->
    <div class="c"><a href="#">Contact</a></div>
</div>

基于TetraDev的答案示例代码

右图:

* {
  outline: .4px dashed red;
}

.main {
  display: flex;
  flex-direction: row;
  align-items: center;
}

h1 {
  flex-basis: 100%;
}

img {
  margin: 0 5px;
  height: 30px;
}
<div class="main">
  <h1>Secure Payment</h1>
  <img src="https://i.stack.imgur.com/i65gn.png">
  <img src="https://i.stack.imgur.com/i65gn.png">
</div>

左图:

* {
  outline: .4px dashed red;
}

.main {
  display: flex;
  flex-direction: row;
  align-items: center;
}

h1 {
  flex-basis: 100%;
  text-align: right;
}

img {
  margin: 0 5px;
  height: 30px;
}
<div class="main">
  <img src="https://i.stack.imgur.com/i65gn.png">
  <img src="https://i.stack.imgur.com/i65gn.png">
  <h1>Secure Payment</h1>
</div>

对于使用Angular和Flex-Layout的用户,请在flex-item容器上使用以下内容:

<div fxLayout="row" fxLayoutAlign="flex-end">

见fxLayoutAlign文档这里和全fxLayout文档在这里

“价格合理的内容:弹性端”在价格盒容器中工作。

.price-box {
    justify-content: flex-end;
}

如果您需要将一项左对齐(例如标题),然后将多项右对齐(例如3张图像),则可以执行以下操作:

h1 {
   flex-basis: 100%; // forces this element to take up any remaining space
}

img {
   margin: 0 5px; // small margin between images
   height: 50px; // image width will be in relation to height, in case images are large - optional if images are already the proper size
}

这就是它的样子(上面的片段中仅包含了relavent CSS)

将以下CSS类添加到样式表中:

.my-spacer {
    flex: 1 1 auto;
}

在左侧的元素和想要右对齐的元素之间放置一个空元素:

<span class="my-spacer"></span>

一样容易

.main {
    display: flex;
    flex-direction:row-reverse;
}

或者你可以用 justify-content: flex-end

.main { display: flex; }
.c { justify-content: flex-end; }

如果要为此使用flexbox,则应该能够做到这一点(display: flex在容器上,flex: 1在项目上以及text-align: right.c):

.main { display: flex; }
.a, .b, .c {
    background: #efefef;
    border: 1px solid #999;
    flex: 1;
}
.b { text-align: center; }
.c { text-align: right; }

...或更可替代地(甚至更简单),如果不需要满足这些条件,则可以justify-content: space-between在容器上使用text-align完全删除规则:

.main { display: flex; justify-content: space-between; }
.a, .b, .c { background: #efefef; border: 1px solid #999; }

这是Codepen 上的演示,可让您快速尝试上述操作。

更加灵活的方法是使用auto左页边距(与在块格式化上下文中使用时相比,灵活项对自动页边距的处理有些不同)。

.c {
    margin-left: auto;
}

更新的小提琴:

.main { display: flex; }
.a, .b, .c { background: #efefef; border: 1px solid #999; }
.b { flex: 1; text-align: center; }
.c {margin-left: auto;}
<h2>With title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <div class="b"><a href="#">Some title centered</a></div>
    <div class="c"><a href="#">Contact</a></div>
</div>
<h2>Without title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <!--<div class="b"><a href="#">Some title centered</a></div>-->
    <div class="c"><a href="#">Contact</a></div>
</div>
<h1>Problem</h1>
<p>Is there a more flexbox-ish way to right align "Contact" than to use position absolute?</p>

干得好。设置justify-content: space-between柔性容器上。

.main { 
    display: flex; 
    justify-content: space-between;
  }
.a, .b, .c { background: #efefef; border: 1px solid #999; }
.b { text-align: center; }
<h2>With title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <div class="b"><a href="#">Some title centered</a></div>
    <div class="c"><a href="#">Contact</a></div>
</div>
<h2>Without title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
<!--     <div class="b"><a href="#">Some title centered</a></div> -->
    <div class="c"><a href="#">Contact</a></div>
</div>
