圆形和文本对齐 CSS3答案

【问题描述】：

我想将圆形下方的文本对齐，完全在中间。

这里是一个 sn-p（我简化了所有内容，因为圆形和文本是由 angular 处理的，所以它们是我的屏幕截图和 sn-p 之间的一些区别）

.circle2 {
  border-radius: 50%;
  width: 18px;
  height: 18px;
  background: RoyalBlue;
  display: inline-block;
  z-index: 2;
}
.wrapper2 {
  display:flex;
  width:100%;
  justify-content: space-around;
  position:relative;

}
.wrapper2:after {
  position:absolute;
  content:'';
  display:block;
  width: 100%;
  top:7px;
  height: 3px;
  background: RoyalBlue;

}
.advanced2 {
  width: 18px;
  height: 18px;
}
.circleActive2 {
  border-radius: 50%;
  width: 25px;
  height: 25px;
  background: RoyalBlue;
  display: inline-block;
}

<div class="w3-container">
  <div class="wrapper2">
    <span>
    <span><div class="circle2 advanced2" ></div>test</span>
    <span><div class="circle2 advanced2 circleActive2" ></div>test2</span>
    <span><div class="circle2 advanced2" ></div>test3</span>
        <span><div class="circle2 advanced2" ></div>test4</span>
        <span><div class="circle2 advanced2" ></div>test5</span>
      </span>
 </div>
</div>

【解决方案1】：

.circles {
  display: flex;
  width: 100%;
  justify-content: space-around;
  position: relative;
}

.circles:after {
  position: absolute;
  content: '';
  display: block;
  width: 100%;
  top: 7px;
  height: 3px;
  background: RoyalBlue;
}

.circles > div {
  display: flex;
  flex-direction: column;
  align-items: center;  
}

.circle {
  border-radius: 50%;
  width: 17px;
  height: 17px;
  background: RoyalBlue;
}

.circle.active {
  width: 25px;
  height: 25px;
  margin-top: -4px;
}

<div class="circles">
  <div><span class="circle"></span>test</div>
  <div><span class="circle active"></span>test2</div>
  <div><span class="circle"></span>test3</div>
  <div><span class="circle"></span>test4</div>
  <div><span class="circle"></span>test5</div>
</div>

【讨论】：

所以如果我理解得很好，circle > div 选择所有
元素，其中父元素是圆形元素并且 felx-direction: column + align-items: center align 完全符合预期？
The > selector flex-direction: column; align-items: center; 将元素放在自己的行上并垂直对齐

【解决方案2】：

我想它应该像下面这样工作：您可以将“.wrapper2”的最大宽度和边距更改为没有问题。

.wrapper2 {
	width:100%;
	position:relative;
	text-align:center;
	max-width:600px;
	margin:50px auto;
}

.wrapper2 > span {
	position:relative;
	width:100%;
	-webkit-flex-flow: row wrap;
	-moz-flex-flow: row wrap;
	flex-flow: row wrap;
	-webkit-justify-content: space-around;
	-moz-justify-content: space-around;
	justify-content: space-around;
	display: -webkit-flex;
	display: -moz-flex;
	display: flex;
}

.wrapper2:after {
	content:"";
	position:absolute;
	display:block;
	width: 100%;
	top:7px;
	left:0;
	height: 4px;
	background: RoyalBlue;
}

.advanced2 {
	width: 18px;
	height: 18px;
	display:block;
	position:relative;
	margin: 0 auto 5px;
	border-radius: 50%;
	width: 18px;
	height: 18px;
	background: RoyalBlue;
	z-index: 2;
}

.circleActive2 {
	margin: -4px auto 1px;
	width: 26px;
	height: 26px;
}

.advanced2 + i {
	font-style:normal;
	display:block;
}

<div class="wrapper2">
  <span>
    <span><div class="advanced2"></div><i>test</i></span>
    <span><div class="advanced2 circleActive2"></div><i>test2</i></span>
    <span><div class="advanced2"></div><i>test3</i></span>
    <span><div class="advanced2"></div><i>test4</i></span>
    <span><div class="advanced2"></div><i>test5</i></span>
   </span>
</div>

希望我能帮上忙！
