How to Align an Image Dead Center with Bootstrap

How to align an image dead center with bootstrap

Twitter Bootstrap v3.0.3 has a class: center-block

Center content blocks
Set an element to display: block and center via margin. Available as a mixin and class.

Just need to add a class .center-block in the img tag, looks like this

<div class="container">
  <div class="row">
    <div class="span4"></div>
    <div class="span4"><img class="center-block" src="logo.png" /></div>
    <div class="span4"></div>
  </div>
</div>

In Bootstrap already has css style call .center-block

.center-block {
    display: block;
    margin-left: auto;
    margin-right: auto;
 }

You can see a sample from here

If you're using Bootstrap v3.0.1 or greater, you should use this solution instead. It doesn't override Bootstrap's styles with custom CSS, but instead uses a Bootstrap feature.

My original answer is shown below for posterity

This is a pleasantly easy fix. Because .img-responsive from Bootstrap already sets display: block, you can use margin: 0 auto to center the image:

.product .img-responsive {
    margin: 0 auto;
}

How do I center an image in Bootstrap?

center-block has been replaced by mx-auto in Bootstrap 4. mx-auto represents auto x-axis margins (margin=left: auto; margin-right: auto) so it
can be used to center display:block or display:flex elements.

          <img class="img-fluid mx-auto" src="https://unsplash.it/200/200" alt="First slide">

Center images inside a div with bootstrap

In Bootstrap classes, add: d-flex justify-content-center align-items-center to the div wrapping the a tags.

In regular CSS without Bootstrap, this is how you center:

You should give the parent div (the one wrapping the a tags) the following CSS properties:

display: flex;
align-items: center;
justify-content: center;
