html - 在带边框的 div 内对齐文本

Question

我正在尝试在圆形 div(具有边框半径)内垂直和水平对齐文本。我尝试了 position:absolute 和 relative

这样的标签

我尝试添加这个:

text-align: center;
display: inline-block;
overflow: hidden;

在我的 CSS 中，但我没有成功。

下面是片段。我想知道在不添加其他 div 的情况下最佳解决方案是什么。提前致谢。

.card-container2 {
  cursor: pointer;
  height: auto;
  perspective: 600;
  position: relative;
  width: auto;
margin:auto;
align-contents:center;
    }

.card-container {

cursor: pointer;
  height: 350px;
  perspective: 600;
  position: relative;
  width: 350px;
    border-radius: 50%;
display:block;
margin-left:auto;
margin-right:auto;

}
.card {
  height: 100%;
  position: absolute;
  transition: all 1s ease-in-out;
 transform-style: preserve-3d;
  width: 100%;
    border-radius: 50%;

-moz-animation-name: dropCard;
    -moz-animation-iteration-count: 1;
    -moz-animation-timing-function: ease-in;
    -moz-animation-duration: 0.3s;

    -webkit-animation-name: dropCard;
    -webkit-animation-iteration-count: 1;
    -webkit-animation-timing-function: ease-in;
    -webkit-animation-duration:0.3s;

    animation-name: dropCard;
    animation-iteration-count: 1;
    animation-timing-function: ease-in;
    animation-duration: 0.3s;

}
.card:hover {
  transform: rotateY(180deg);
}
.card .side {
  backface-visibility: hidden;
  border-radius: 6px;
  height: 100%;
  position: absolute;
  overflow: hidden;
  width: 100%;
  background:#000;
  border-radius: 50%;
}

.card .back {

  color: #000;
  line-height: 24px;
font-weight: bold;
  text-align: center;
    border-radius: 50%;
  transform: rotateY(180deg);
}


@-moz-keyframes dropCard {
    0% {
        -moz-transform: translateY(-100px);
    }

  100% {
        -moz-transform: translateY(0);
    }
}
@-webkit-keyframes dropCard {
    0% {
        -webkit-transform: translateY(-100px);
    }
    100% {

    }
}

@keyframes dropCard {
    0% {
        transform: translateY(-100px);
    }
    100% {
        transform: translateY(0);
    }

您的计划是在 backside rounded div .back .side 内对齐文本吗？正确居中，然后从 <p> tag 中删除边距并添加 padding-top至 .back

.card .back {
  background: #F1F1F1;
  color: #000;
  line-height: 24px;
font-weight: bold;
  text-align: center;
    border-radius: 50%;
  transform: rotateY(180deg);
  padding-top:75px;
  box-sizing:border-box;
}
p{
  margin:5px 0px;
  text-align:center;
}

.card-container2 {
  cursor: pointer;
  height: auto;
  perspective: 600;
  position: relative;
  width: auto;
margin:auto;
align-contents:center;
    }

.card-container {

cursor: pointer;
  height: 350px;
  perspective: 600;
  position: relative;
  width: 350px;
    border-radius: 50%;
display:block;
margin-left:auto;
margin-right:auto;

}
.card {
  height: 100%;
  position: absolute;
  transition: all 1s ease-in-out;
 transform-style: preserve-3d;
  width: 100%;
    border-radius: 50%;

-moz-animation-name: dropCard;
    -moz-animation-iteration-count: 1;
    -moz-animation-timing-function: ease-in;
    -moz-animation-duration: 0.3s;

    -webkit-animation-name: dropCard;
    -webkit-animation-iteration-count: 1;
    -webkit-animation-timing-function: ease-in;
    -webkit-animation-duration:0.3s;

    animation-name: dropCard;
    animation-iteration-count: 1;
    animation-timing-function: ease-in;
    animation-duration: 0.3s;

}
.card:hover {
  transform: rotateY(180deg);
}
.card .side {
  backface-visibility: hidden;
  border-radius: 6px;
  height: 100%;
  position: absolute;
  overflow: hidden;
  width: 100%;
  background:#000;
  border-radius: 50%;
}

.card .back {
  background: #F1F1F1;
  color: #000;
  line-height: 24px;
font-weight: bold;
  text-align: center;
    border-radius: 50%;
  transform: rotateY(180deg);
  padding-top:75px;
  box-sizing:border-box;
}
p{
  margin:5px 0px;
  text-align:center;
}


@-moz-keyframes dropCard {
    0% {
        -moz-transform: translateY(-100px);
    }

  100% {
        -moz-transform: translateY(0);
    }
}
@-webkit-keyframes dropCard {
    0% {
        -webkit-transform: translateY(-100px);
    }
    100% {
        -webkit-transform: translateY(0);
    }
}

@keyframes dropCard {
    0% {
        transform: translateY(-100px);
    }
    100% {
        transform: translateY(0);
    }
}
