How to vertically align an image inside a div


Question

How can you align an image inside of a containing div?

Example

In my example, I need to vertically center the <img> in the <div> with class ="frame":

<div class="frame" style="height: 25px;">
    <img src="http://jsfiddle.net/img/logo.png" />
</div>

.frame's height is fixed and the image's height is unknown. I can add new elements in .frame if that's the only solution. I'm trying to do this on Internet  Explorer 7 and later, WebKit, Gecko.

See the jsfiddle here.

.frame {
    height: 25px;      /* Equals maximum image height */
    line-height: 25px;
    width: 160px;
    border: 1px solid red;

    text-align: center;
    margin: 1em 0;
}
img {
    background: #3A6F9A;
    vertical-align: middle;
    max-height: 25px;
    max-width: 160px;
}
<div class=frame>
   <img src="http://jsfiddle.net/img/logo.png" height=250 />
</div>
<div class=frame>
   <img src="http://jsfiddle.net/img/logo.png" height=25 />
</div>
<div class=frame>
   <img src="http://jsfiddle.net/img/logo.png" height=23 />
</div>
<div class=frame>
   <img src="http://jsfiddle.net/img/logo.png" height=21 />
</div>
<div class=frame>
   <img src="http://jsfiddle.net/img/logo.png" height=19 />
</div>
<div class=frame>
    <img src="http://jsfiddle.net/img/logo.png" height=17 />
</div>
<div class=frame>
    <img src="http://jsfiddle.net/img/logo.png" height=15 />
 </div>
<div class=frame>
    <img src="http://jsfiddle.net/img/logo.png" height=13 />
 </div>
<div class=frame>
    <img src="http://jsfiddle.net/img/logo.png" height=11 />
 </div>
<div class=frame>
    <img src="http://jsfiddle.net/img/logo.png" height=9 />
 </div>
<div class=frame>
    <img src="http://jsfiddle.net/img/logo.png" height=7 />
 </div>
<div class=frame>
    <img src="http://jsfiddle.net/img/logo.png" height=5 />
 </div>
<div class=frame>
    <img src="http://jsfiddle.net/img/logo.png" height=3 />
 </div>

The only (and the best cross-browser) way as I know is to use an inline-block helper with height: 100% and vertical-align: middle on both elements.

So there is a solution: http://jsfiddle.net/kizu/4RPFa/4570/

.frame {
    height: 25px;      /* Equals maximum image height */
    width: 160px;
    border: 1px solid red;
    white-space: nowrap; /* This is required unless you put the helper span closely near the img */

    text-align: center;
    margin: 1em 0;
}

.helper {
    display: inline-block;
    height: 100%;
    vertical-align: middle;
}

img {
    background: #3A6F9A;
    vertical-align: middle;
    max-height: 25px;
    max-width: 160px;
}
<div class="frame">
    <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=250px />
</div>
<div class="frame">
    <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=25px />
</div>
<div class="frame">
    <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=23px />
</div>
<div class="frame">
    <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=21px />
</div>
<div class="frame">
    <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=19px />
</div>
<div class="frame">
    <span class="helper"></span>
    <img src="http://jsfiddle.net/img/logo.png" height=17px />
</div>
<div class="frame">
    <span class="helper"></span>
    <img src="http://jsfiddle.net/img/logo.png" height=15px />
</div>
<div class="frame">
    <span class="helper"></span>
    <img src="http://jsfiddle.net/img/logo.png" height=13px />
</div>
<div class="frame">
    <span class="helper"></span>
    <img src="http://jsfiddle.net/img/logo.png" height=11px />
</div>
<div class="frame">
    <span class="helper"></span>
    <img src="http://jsfiddle.net/img/logo.png" height=9px />
</div>
<div class="frame">
    <span class="helper"></span>
    <img src="http://jsfiddle.net/img/logo.png" height=7px />
</div>
<div class="frame">
    <span class="helper"></span>
    <img src="http://jsfiddle.net/img/logo.png" height=5px />
</div>
<div class="frame">
    <span class="helper"></span>
    <img src="http://jsfiddle.net/img/logo.png" height=3px />
</div>

Or, if you don't want to have an extra element in modern browsers and don't mind using Internet Explorer expressions, you can use a pseudo-element and add it to Internet Explorer using a convenient Expression, that runs only once per element, so there won't be any performance issues:

The solution with :before and expression() for Internet Explorer: http://jsfiddle.net/kizu/4RPFa/4571/

.frame {
    height: 25px;      /* Equals maximum image height */
    width: 160px;
    border: 1px solid red;
    white-space: nowrap;

    text-align: center;
    margin: 1em 0;
}

.frame:before,
.frame_before {
    content: "";
    display: inline-block;
    height: 100%;
    vertical-align: middle;
}

img {
    background: #3A6F9A;
    vertical-align: middle;
    max-height: 25px;
    max-width: 160px;
}

/* Move this to conditional comments */
.frame {
    list-style:none;
    behavior: expression(
        function(t){
            t.insertAdjacentHTML('afterBegin','<span class="frame_before"></span>');
            t.runtimeStyle.behavior = 'none';
        }(this)
    );
}
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=250px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=25px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=23px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=21px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=19px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=17px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=15px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=13px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=11px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=9px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=7px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=5px /></div>
<div class="frame"><img src="http://jsfiddle.net/img/logo.png" height=3px /></div>


How it works:

  1. When you have two inline-block elements near each other, you can align each to other's side, so with vertical-align: middle you'll get something like this:

    Two aligned blocks

  2. When you have a block with fixed height (in px, em or another absolute unit), you can set the height of inner blocks in %.

  3. So, adding one inline-block with height: 100% in a block with fixed height would align another inline-block element in it (<img/> in your case) vertically near it.

This might be useful:

div {
    position: relative;
    width: 200px;
    height: 200px;
}
img {
    position: absolute;
    top: 0;
    bottom: 0;
    margin: auto;
}
.image {
    min-height: 50px
}

matejkramny's solution is a good start, but oversized images have a wrong ratio.

Here's my fork:

Demo: https://jsbin.com/lidebapomi/edit?html,css,output

HTML:

<div class="frame">
  <img src="foo"/>
</div>

CSS:

.frame {
    height: 160px; /* Can be anything */
    width: 160px; /* Can be anything */
    position: relative;
}
img {
    max-height: 100%;
    max-width: 100%;
    width: auto;
    height: auto;
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    margin: auto;
}

A three-line solution:

position: relative;
top: 50%;
transform: translateY(-50%);

This applies to anything.

From here.

A pure CSS solution:

.frame {
  margin: 1em 0;
  height: 35px;
  width: 160px;
  border: 1px solid red;
  position: relative;
}

img {
  max-height: 25px;
  max-width: 160px;
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  margin: auto;
  background: #3A6F9A;
}
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=250 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=25 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=23 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=21 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=19 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=17 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=15 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=13 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=11 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=9 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=7 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=5 />
</div>
<div class=frame>
  <img src="http://jsfiddle.net/img/logo.png" height=3 />
</div>

Key stuff

// position: relative; - in .frame holds the absolute element within the frame
// top: 0; bottom: 0; left: 0; right: 0; - this is key for centering a component
// margin: auto; - centers the image horizontally & vertically

For a more modern solution, and if there is no need to support legacy browsers, you can do this:

.frame {
    display: flex;
    /**
    Uncomment 'justify-content' below to center horizontally.
    ✪ Read below for a better way to center vertically and horizontally.
    **/

    /* justify-content: center; */
    align-items: center;
}

img {
    height: auto;

    /**
    ✪ To center this image both vertically and horizontally,
    in the .frame rule above comment the 'justify-content'
    and 'align-items' declarations,
    then  uncomment 'margin: auto;' below.
    **/

    /* margin: auto; */
}

/* Styling stuff not needed for demo */
.frame {
    max-width: 900px;
    height: 200px;
    margin: auto;
    background: #222;
}
p {
    max-width: 900px;
    margin: 20px auto 0;
}
img {
    width: 150px;
}
<div class="frame">
    <img src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/9988/hand-pointing.png">
</div>
