Question

我有以下代码片段，其中有2个div，一个接一个。在.circle我有一个悬停效果，其中边框在图像周围扩展。然后第二个div在这个下面“流动”，并将保留其他内容。

我只希望悬停效果出现在img周围。为实现此目的，我设置了p{position: absolute;}，因此边框不会包含p标记。

问题是，如何在2个div之间保持一致的边距？

注意：

我不知道img下会有多少行文字，所以硬编码.circle{margin-top: ?px}不是一个选项。
当我将p标记悬停时，我希望悬停效果仍然触发。

.circle {
  display: inline-block;
  margin: 40px 20px;
  vertical-align: middle;
  -webkit-transform: translateZ(0);
  transform: translateZ(0);
  box-shadow: 0 0 1px rgba(0, 0, 0, 0);
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  -moz-osx-font-smoothing: grayscale;
  position: relative;
  cursor: pointer;
}

.circle > p {
  position: absolute;
  display: block;
  width: 100%;
  margin-top: 20px;
  text-align: center;
}

.circle>img {
  border-radius: 50%;
  width: 100%;
  height: auto;
}

.circle:before {
  content: '';
  position: absolute;
  border: #54314E solid 4px;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-property: top, right, bottom, left;
  transition-property: top, right, bottom, left;
  border-radius: 50%;
}

.circle:hover:before,
.circle:focus:before,
.circle:active:before,
.circle.active:before {
  top: -15px;
  right: -15px;
  bottom: -15px;
  left: -15px;
}

#underDiv {
  display: block;
  width: 100px;
  height: 100px;
  background-color: #f00;
}

<div class="circle">
  <img src="http://placehold.it/150x150">
  <p>OUR SERVICE PROMISE</p>
</div>

<div id="underDiv"><div>

Answer 1

从圈子中删除p标记，然后添加另一个包裹它们的div。根据该包装器的悬停状态触发动画

＆＃13;

.circle {
  display: inline-block;
  margin: 40px 20px 0 20px;
  vertical-align: middle;
  -webkit-transform: translateZ(0);
  transform: translateZ(0);
  box-shadow: 0 0 1px rgba(0, 0, 0, 0);
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  -moz-osx-font-smoothing: grayscale;
  position: relative;
  cursor: pointer;
}

.circle>img {
  border-radius: 50%;
  width: 100%;
  height: auto;
}

.circle:before {
  content: '';
  position: absolute;
  border: #54314E solid 4px;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-property: top, right, bottom, left;
  transition-property: top, right, bottom, left;
  border-radius: 50%;
}

.circle-wrap:hover .circle:before,
.circle-wrap:focus .circle:before,
.circle-wrap:active .circle:before,
.circle-wrap.active .circle:before {
  top: -15px;
  right: -15px;
  bottom: -15px;
  left: -15px;
}

#underDiv {
  display: block;
  width: 100px;
  height: 100px;
  background-color: #f00;
}

＆＃13;

<div class="circle-wrap">
  <div class="circle">
    <img src="http://placehold.it/150x150">
  </div>
  <p>OUR SERVICE PROMISE</p>
</div>
<div id="underDiv"><div>

Answer 2

我认为可能有更好的设置来处理这种效果，但这是一个解决方案，给出了当前的设置。

在圈子的:hover上添加一些额外的margin-bottom来计算边框圈增长的额外金额。例如，您的圈子的半径增长15px，因此margin-bottom上的.circle增加15px。然后将transition添加到margin-bottom上的.circle进行转换，添加与圈边框增长相同的速度。

＆＃13;

.circle {
  display: inline-block;
  margin: 40px 20px;
  vertical-align: middle;
  -webkit-transform: translateZ(0);
  transform: translateZ(0);
  box-shadow: 0 0 1px rgba(0, 0, 0, 0);
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  -moz-osx-font-smoothing: grayscale;
  position: relative;
  cursor: pointer;
   -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-property: margin-bottom;
  transition-property: margin-bottom;
}

.circle > p {
  position: absolute;
  display: block;
  width: 100%;
  margin-top: 20px;
  text-align: center;
}

.circle>img {
  border-radius: 50%;
  width: 100%;
  height: auto;
}

.circle:before {
  content: '';
  position: absolute;
  border: #54314E solid 4px;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-property: top, right, bottom, left;
  transition-property: top, right, bottom, left;
  border-radius: 50%;
}

.circle:hover {
  margin-bottom: 55px;
}

.circle:hover:before,
.circle:focus:before,
.circle:active:before,
.circle.active:before {
  top: -15px;
  right: -15px;
  bottom: -15px;
  left: -15px;
}

#underDiv {
  display: block;
  width: 100px;
  height: 100px;
  background-color: #f00;
}

＆＃13;

<div class="circle">

</div>

<div id="underDiv"><div>

只需将圆圈包裹在一个新元素中，然后使用新元素在圆圈周围绘制圆环，然后在将鼠标悬停在包裹圆圈和段落的父级上方时触发圆环展开。

＆＃13;

.circle {
  display: inline-block;
  margin: 40px 20px;
  vertical-align: middle;
  -webkit-transform: translateZ(0);
  transform: translateZ(0);
  box-shadow: 0 0 1px rgba(0, 0, 0, 0);
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  -moz-osx-font-smoothing: grayscale;
  cursor: pointer;
}

.circle > p {
  display: block;
  width: 100%;
  text-align: center;
  margin: 40px 0 0;
}
.circle>div {
  position: relative;
}

.circle>div:before {
  content: '';
  position: absolute;
  border: #54314E solid 4px;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-property: top, right, bottom, left;
  transition-property: top, right, bottom, left;
  border-radius: 50%;
  z-index: 1;
}

.circle>div>img {
  border-radius: 50%;
  width: 100%;
  height: auto;
}

.circle:hover > div:before {
  top: -15px;
  right: -15px;
  bottom: -15px;
  left: -15px;
}

#underDiv {
  display: block;
  width: 100px;
  height: 100px;
  background-color: #f00;
}

＆＃13;

<div class="circle">
  <div>
    <img src="http://placehold.it/150x150">
  </div>
  <p>OUR SERVICE PROMISE</p>
</div>

<div id="underDiv"><div>
