html - CSS - 在除最后一个元素之外的元素之间添加空格

Question

关于这个 jsfiddle 你可以看到我有 6 个圆圈:第一行有 3 个，第二行有 3 个。

我想在它们之间添加一些空间，并计划使用 margin-right: 5px。如果我这样做，问题是最后一个元素(圆圈 3 和圆圈 6)的右边也会有这个额外的 5px，这是我不想要的(因为它们旁边没有元素)。有解决方法吗？

我需要的是:

(第 1 圈)5px 空间(第 2 圈)5px 空间(第 3 圈)

谢谢

HTML:

<div class="circle circlebackground">
    <p>Circle 1</p>
    <div class="innercircle">
        <p>by Angela</p>
    </div>
</div>
<div class="circle circlebackground">
    <p>Circle 2</p>
    <div class="innercircle">
        <p>by Angela</p>
    </div>
</div>
<div class="circle circlebackground">
    <p>Circle 3</p>
    <div class="innercircle">
        <p>by Angela</p>
    </div>
</div>

<div class="circle circlebackground clear">
    <p>Circle 4</p>
    <div class="innercircle">
        <p>by Angela</p>
    </div>
</div>
<div class="circle circlebackground">

如果你真的想给margin-right，你可以使用这种类型的css。

.circle {
    float: left;
    margin-bottom: 10px;
    width: 200px;
    height: 200px;
    border-radius: 50%;
    margin-left:5px;   /*added*/
    position: relative;
    box-shadow: inset 0 0 0 16px rgba(255, 255, 255, 0.6), 0 1px 2px rgba(0, 0, 0, 0.1);
    -webkit-transition: all 0.4s ease-in-out;
    -moz-transition: all 0.4s ease-in-out;
    -o-transition: all 0.4s ease-in-out;
    -ms-transition: all 0.4s ease-in-out;
    transition: all 0.4s ease-in-out;
}
.circle:nth-of-type(3n+0) {
    margin-right:0px;
}
