How to vertically align an image inside a div?

Question

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 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 IE≥7, Webkit, Gecko.

See the jsfiddle here

.frame {
    height: 25px;      /* equals max 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>

Answer 1

The old JSFiddle link I posted here didnt work anymore, thats probably the reason for the downvote. Just for the sake of this being a valid answer i still want to post the jQuery solution again. This works for every element that has the v_align class applied to it. It will be vertical centered in the parent and on resizing of the window it will be recalculated.

Link to the JSFiddle

$(document).ready(function() {
  // define the class that vertial aligns stuff
  var objects = '.v_align';
  // initial setup
  verticalAlign(objects);

  // register resize event listener
  $(window).resize(function() {
    verticalAlign(objects);
  });
});

function verticalAlign(selector) {
  $(selector).each(function(val) {
    var parent_height = $(this).parent().height();
    var dif = parent_height - $(this).height()
    // should only work if the parent is larger than the element
    var margin_top = dif > 0 ? dif/2 : 0;
    $(this).css("margin-top", margin_top + "px");
  });
}

3 line solution:

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

This applies to anything.

From here.

Answer 3

A PURE CSS Solution:

http://jsfiddle.net/3MVPM/

The CSS:

.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;  
}

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

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;
}

Answer 5

This way you can center an image vertically (demo):

div{
  height:150px; //IE7fix
  line-height: 150px;
}
img{
  vertical-align: middle;
  margin-bottom:0.25em;
}

There is a super easy solution with flexbox!

.frame {
    display: flex;
    align-items: center;
}
