在带边框的 div 中对齐文本

Question

I am trying to align text vertically and horizontally within a rounded div (with a border radius). I tried tags like position:absolute and relative

I tried adding this :

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

in my CSS but I had no success.

Below is the snippet. I wonder what the optimal solution would be without adding other divs. Thanks in advance.

 .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); } @-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); } } IMG.displayed { display: block; margin-left: auto; margin-right: auto }

Answer 1

Is your plan is to align text within backside rounded div .back .side properly in center, then remove margin from <p> tag and add padding-top to .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); } } IMG.displayed { display: block; margin-left: auto; margin-right: auto }

 <p style="text-align: center;">&nbsp;</p> <div class="card-container2"> <div class="card-container"> <div class="card"> <div class="side" style="text-align: center;"><img class="displayed" src="IMAGE" alt="" width="350" height="350" /></div> <div class="side back"> <p><span style="font-size: 14pt; font-family: arial, helvetica, sans-serif; color: #000;">Campaign Name: 11111111&nbsp;</span></p> <p><span style="color: #000; font-size: 14pt;"><span style="font-family: arial, helvetica, sans-serif;">Campaign Dates:&nbsp;</span><span style="font-family: arial, helvetica, sans-serif;">333333333333333 -&nbsp;22222222222&nbsp;</span></span></p> <p><span style="color: #000; font-size: 14pt;">&nbsp;</span></p> <p><span style="color: #000; font-size: 14pt;">Length of campaign:4444444444444&nbsp;</span></p> <p><span style="color: #000; font-size: 14pt;">Days left of campaign:&nbsp;55555555555555555}&nbsp;</span></p> </div> </div> </div> </div>

Answer 2

Simply add a padding of 10% to .card .back

 .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; padding:10%; 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% { -webkit-transform: translateY(0); } } @keyframes dropCard { 0% { transform: translateY(-100px); } 100% { transform: translateY(0); } } IMG.displayed { display: block; margin-left: auto; margin-right: auto }

 <p style="text-align: center;">&nbsp;</p> <div class="card-container2"> <div class="card-container"> <div class="card"> <div class="side" style="text-align: center;"><img class="displayed" src="IMAGE" alt="" width="350" height="350" /></div> <div class="side back"> <p><span style="font-size: 14pt; font-family: arial, helvetica, sans-serif; color: #000;">Campaign Name: 11111111&nbsp;</span></p> <p><span style="color: #000; font-size: 14pt;"><span style="font-family: arial, helvetica, sans-serif;">Campaign Dates:&nbsp;</span><span style="font-family: arial, helvetica, sans-serif;">333333333333333 -&nbsp;22222222222&nbsp;</span></span></p> <p><span style="color: #000; font-size: 14pt;">&nbsp;</span></p> <p><span style="color: #000; font-size: 14pt;">Length of campaign:4444444444444&nbsp;</span></p> <p><span style="color: #000; font-size: 14pt;">Days left of campaign:&nbsp;55555555555555555}&nbsp;</span></p> </div> </div> </div> </div>

Answer 3

Add this to your CSS just after your .card .back line..

.back>p:first-child {
    padding-top: 40px;
}

EDIT:
Also you can reduce the line height in .card .back to prevent overflow. I reduced it to 20px. Seemed to fit better, but that is a matter of preference..

Since the requirement is, as mentioned in the comments , to center the content in the circle vertically and horizontally, we can use flexbox for that.

Like so:

 * { margin: 0; padding: 0; } .card-container2 { cursor: pointer; height: auto; perspective: 600; position: relative; width: auto; margin: auto; text-align: 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%; } .card .side { backface-visibility: hidden; border-radius: 6px; height: 100%; position: absolute; overflow: hidden; width: 100%; background: #000; border-radius: 50%; display: flex; flex-direction: column; justify-content: center; text-align:center; } .card .back { background: #F1F1F1; color: #000; line-height: 24px; font-weight: bold; text-align: center; border-radius: 50%; }

 <div class="card-container2"> <div class="card-container"> <div class="card"> <div class="side" style="text-align: center;"> <img class="displayed" src="IMAGE" alt="" width="350" height="350" /> </div> <div class="side back"> <p><span style="font-size: 14pt; font-family: arial, helvetica, sans-serif; color: #000;">Campaign Name: 11111111&nbsp;</span> </p> <p><span style="color: #000; font-size: 14pt;"><span style="font-family: arial, helvetica, sans-serif;">Campaign Dates:&nbsp;</span><span style="font-family: arial, helvetica, sans-serif;">333333333333333 -&nbsp;22222222222&nbsp;</span></span> </p> <p><span style="color: #000; font-size: 14pt;">&nbsp;</span> </p> <p><span style="color: #000; font-size: 14pt;">Length of campaign:4444444444444&nbsp;</span> </p> <p><span style="color: #000; font-size: 14pt;">Days left of campaign:&nbsp;55555555555555555&nbsp;</span> </p> </div> </div> </div> </div>

Note that this does not address any overflow issues as you can see.
