[html] How to center div vertically inside of absolutely positioned parent div

I am trying to get blue container in the middle of pink one, however seems vertical-align: middle; doesn't do the job in that case.

<div style="display: block; position: absolute; left: 50px; top: 50px;">
    <div style="text-align: left; position: absolute;height: 56px;vertical-align: middle;background-color: pink;">
        <div style="background-color: lightblue;">test</div>
    </div>
</div>

Result:

Expectation:

Please suggest how can I achieve that.

Jsfiddle

use this :

.Absolute-Center {
    margin: auto;
    position: absolute;
    top: 0; left: 0; bottom: 0; right: 0;
}

You can do it by using display:table; in parent div and display: table-cell; vertical-align: middle; in child div

<div style="display:table;">_x000D_
      <div style="text-align: left;  height: 56px;  background-color: pink; display: table-cell; vertical-align: middle;">_x000D_
          <div style="background-color: lightblue; ">test</div>_x000D_
      </div>_x000D_
  </div>

An additional simple solution

HTML:

<div id="d1">
    <div id="d2">
        Text
    </div>
</div>

CSS:

#d1{
    position:absolute;
    top:100px;left:100px;
}

#d2{
    border:1px solid black;
    height:50px; width:50px;
    display:table-cell;
    vertical-align:middle;
    text-align:center;  
}

For only vertical center

    <div style="text-align: left; position: relative;height: 56px;background-color: pink;">
        <div style="background-color: lightblue;position:absolute;top:50%;    transform: translateY(-50%);">test</div>
    </div>

I always do like this, it's a very short and easy code to center both horizontally and vertically

.center{
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

<div class="center">Hello Centered World!</div>

Here is simple way using Top object.

eg: If absolute element size is 60px.

.absolute-element { 
    position:absolute; 
    height:60px; 
    top: calc(50% - 60px);
}

You may use display:table/table-cell;

.a{_x000D_
   position: absolute; _x000D_
  left: 50px; _x000D_
  top: 50px;_x000D_
  display:table;_x000D_
}_x000D_
.b{_x000D_
  text-align: left; _x000D_
  display:table-cell;_x000D_
  height: 56px;_x000D_
  vertical-align: middle;_x000D_
  background-color: pink;_x000D_
}_x000D_
.c {_x000D_
  background-color: lightblue;_x000D_
}

<div class="a">_x000D_
  <div  class="b">_x000D_
    <div class="c" >test</div>_x000D_
  </div>_x000D_
</div>

Use flex blox in your absoutely positioned div to center its content.

See example https://plnkr.co/edit/wJIX2NpbNhO34X68ZyoY?p=preview

.some-absolute-div {    
  display: -webkit-box;
  display: -webkit-flex;
  display: -moz-box;
  display: -moz-flex;
  display: -ms-flexbox;
  display: flex;

  -webkit-box-pack: center;
  -ms-flex-pack: center;
  -webkit-justify-content: center;
  -moz-justify-content: center;
  justify-content: center;

  -webkit-box-align: center;
  -ms-flex-align: center;
  -webkit-align-items: center;
  -moz-align-items: center;
  align-items: center;
}

Center vertically and horizontally:

.parent{
  height: 100%;
  position: absolute;
  width: 100%;
  top: 0;
  left: 0;
}
.c{
  position: absolute;
  top: 50%;
  left: 0;
  right: 0;
  transform: translateY(-50%);
}
