How to make an image center (vertically & horizont

Question

I have a div 200 x 200 px. I want to place a 50 x 50 px image right in the middle of the div.

How can it be done?

I am able to get it centered horizontally by using text-align: center for the div. But vertical alignment is the issue..

Answer 1

another way is to create a table with valign, of course. This would work regardless of you knowing the div's height or not.

<div>
   <table width="100%" height="100%" align="center" valign="center">
   <tr><td>
      <img src="foo.jpg" alt="foo" />
   </td></tr>
   </table>
</div>

but you should always stick to just css whenever possible.

Answer 2

This is coming a bit late, but here's a solution I use to vertical align elements within a parent div.

This is useful for when you know the size of the container div, but not that of the contained image. (this is frequently the case when working with lightboxes or image carousels).

Here's the styling you should try:

 container div
 {
   display:table-cell;
   vertical-align:middle;

   height:200px;
   width:200px;
 }

 img
 {
   /*Apply any styling here*/        
 }

Use Flexbox :https://scotch.io/tutorials/a-visual-guide-to-css3-flexbox-properties

.outerDiv{
            display: flex;
            flex-direction: column;
            justify-content: center;  // Centering y-axis
            align-items :center ; //Centering x-axis
          }

Answer 4

Personally, I'd place it as the background image within the div, the CSS for that being:

#demo {
    background: url(bg_apple_little.gif) no-repeat center center;
    height: 200px;
    width: 200px;
}

(Assumes a div with id="demo" as you are already specifying height and width adding a background shouldn't be an issue)

Let the browser take the strain.

Answer 5

This works correctly:

display: block;
margin-left: auto;
margin-right: auto 

else try this if the above only gives you horizontal centering:

.outerContainer {
   position: relative;
}

.innerContainer {
   width: 50px; //your image/element width here
   height: 50px; //your image/element height here
   overflow: auto;
   margin: auto;
   position: absolute;
   top: 0; left: 0; bottom: 0; right: 0;
}

Answer 6

here's another method to center everything within anything.

Working Fiddle

HTML: (simple as ever)

<div class="Container">
    <div class="Content"> /*this can be an img, span, or everything else*/
        I'm the Content
    </div>
</div>

CSS:

.Container
{
    text-align: center;
}

    .Container:before
    {
        content: '';
        height: 100%;
        display: inline-block;
        vertical-align: middle;
    }

.Content
{
    display: inline-block;
    vertical-align: middle;
}

Benefits

The Container and Content height are unknown.

Centering without specific negative margin, without setting the line-height (so it works well with multiple line of text) and without a script, also Works great with CSS transitions.
