centering fluid image within fluid div

[mel99]

I hope I'm posting in the correct category, I'm using Twitter Bootstrap and I'm trying to center a fluid image within a fluid div. Underneath the image is some text which I want aligned left so using text-align center to the parent div does not work. This is the HTML:

<div class="row-fluid">
<div class="span4 well">
<img src="img.png" />
<h2><a href="#">Some text</a></h2>
<p class="well-text">Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, </p>
</div>
</div>

The class "well" gives the span4 a nice soft grey background, but the image is aligned to the right of the well. Anyone familiar with Bootstrap that can see what I'm missing? I bet there's an easy fix for this.

If you are able to wrap the image in a <p> or <div> you can set the <p> or <div> to text-align: center. That's my preferred way, as I don't like / trust inline elements butting up agains block elements.

Another option would simply be to add this to your CSS:

img {display: block;margin:0 auto;}

That way, you don't have to touch the HTML. If you don't want this to apply to all images, you'll need to make it more specific, though.

Hi Mel99. I use Twitter Bootstrap also. Here are a couple possibilities I see...

1) For responsive pages I always start a new section like this:

<div class="container-fluid">
   <div class="row-fluid">

Your example is missing the container-fluid class. That may not be affecting your well, but it sure is easy to test

2) It sounds like you want an image with a caption, all in a shaded box with round corners. You may need to use something besides a "well" to do that...
This would give you a captioned image...

<figure>
  <img src="../images/some.jpg" />
  <figcaption>Words for below the picture</figcaption>
</figure>

...and I assume you know how to create the bordered box with a light background to put it into.

3) Or you could try just forcing everything into position like this (not sure if it will work because I have never used their "wells")

<div class="row-fluid">
<div class="span4 well" style="text-align:center;" >
  <img src="img.png" />
  <div class="well-text clearfix" style="text-align:left;" >
    <h2><a href="#">Some text</a></h2>
    <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, </p>
  </div>
</div>
</div>

Note that I moved the "well-text" class to include both the <h2> and the <p>. Also the "clearfix" may not be needed. Experiment and let us know the result.

Maybe none of these work as-is, but they are food for thought
