如何使用百分比在文本和横向上制作DIV的文本中心？

时间：2017-05-31 05:45:08

标签： html css html5 css3 responsive-design

我可以在中心创建文本，但使用px值。当我尝试使用百分比时，它无法正常工作。我试过 display：table;并显示：table-cell 以及 display：flex; 辩解内容：中心; //水平居中 对齐项：中心; ，但它不起作用。

我的父母div有高度：7.7％。

注意：我已更新完整的标题代码

您可以使用flex来实现相同目标。

您可以在容器上使用display: table;，在子项上使用display: table-cell;，使您的导航元素垂直和水平居中。然后，Ypu可以根据您需要的布局设置容器和元素width。

可能的例子：

＆＃13;
＆＃13; 
.vav-main{
  position: relative;
  width: 100%;
  height: 100%;
 }


.navbar{
  display: table;
  width: 100%;
  background-color: #ffffff;
  border: solid 1px #b8b8b8;
 }

.navlogo {
  height: 100;
  background-color: #ffffff;
  width: 5%;
 }

.navlogo span {
  font-family: SourceSansPro;
  font-size: 24px;
  font-weight: bold;
 }
 
 .navbar-header {
  display: table-cell;
  padding: 3.5%;
  vertical-align: middle;
  text-align: center;
 }
＆＃13; 
<div class="vav-main">
  <nav class="navbar navbar-default">
    <div class="navbar-header navlogo">
      <span><a href ="#">DS</a></span>
    </div>
    <div class="navbar-header">
       ........
    </div>
 </nav>
</div>

您可能正在使用bootstrap进行此操作，如果有，那么您可以像下面一样尝试，删除span tag，因为a和span标记都是inline elements，所以你可以使用一个如果需要的话。

＆＃13;
＆＃13; 
.nav-main {
  width: 100%;
  height: 100%;
}

.nav-main > .navheader {
  width: 100%;
  height: 7.7%;
  background-color: #ffffff;
}

.navlogo {
  width: 100%;
  height: 100%;
  background-color: #ffffff;
  text-align: center;
}

.navlogo > a {
  font-family: SourceSansPro;
  font-size: 24px;
  font-weight: bold;
  display: inline-block;
  margin-top: 8px;
}
＆＃13; 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<div class="nav-main">
  <nav class="navbar navbar-default navheader">
    <div class="navbar-header navlogo">
      <a href="#">DS</a>
    </div>
    <div>
    </div>
  </nav>
</div>

我不修改你的代码，我只是写一些代码块。希望这对你有所帮助。如您所见，石灰块内的文本始终按水平线对齐中间，垂直对齐中间。

$('#header .text').css('left', 'calc(50% - '+$('#header .text').css('width')+' / 2)');
$('#header .text').css('top', 'calc(50% - '+$('#header .text').css('height')+' / 2)');
#header{
  width:100%;
  height:200px;
  border:1px blue solid;
}
#box{
  width:30%;
  height:80%;
  background-color:lime;
  text-align:center;
  position:relative;
}
#box .text{
  border:1px red solid;
  position:absolute;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div id='header'>
<div id='box'>
  <div class='text'>abchghjghj</div>
</div>
</div>
