Problem with absolute positioning in Firefox and Chrome

Question

I don't understand why FF and Chrome render my page differently. Here's a screenie of it in

firefox: firefox example http://grab.by/65Bn

and here's one in chrome

chrome: chrome example http://grab.by/65BB

fieldset has a relative position and the image has an absolute position.

here's the basic structure:

<fieldset class="passenger-info">
  <legend>Passenger 1</legend>
  <div class="remove-me">
    <img src="/images/delete-icon-sm.png" />
  </div>
</fieldset>

basically the image is declared right after the legend.

here's the css for fieldset:

.passenger-info {
  background:none repeat scroll 0 0 #F2F2F2;
  border:1px solid #9D240F;
  display:inline;
  float:left;
  margin-bottom:10px;
  margin-right:10px;
  padding:3px 10px;
  position:relative;
  width:350px;
}

and for the remove-me image:

.remove-me {
  border:1px solid red;
  position:absolute;
  right:0;
  top:0;
}

it's totally weird. I tried putting the fieldset padding out, and the image moves up a little, but still not at the corner.

This post shows that FF does indeed have problems with rendering fieldsets.

Is there a better way of doing a fix without using a browser specific hack?

Answer 1

I can't believe this is 4 years old and still not answered. I searched every where for this answer. Here is what I did to use position absolute on an image within a fieldset. From here, change your right and top positioning to make it work for you in Firefox. (leave your original class in place for IE, Chrome, Safari, Opera)

@-moz-document url-prefix() { 
  .remove-me {
    border:1px solid red;
    position:absolute;
    right:0;
    top:0;
  }
}

This is a Firefox Hack that I'm told works for every version of Firefox. I'm using Firefox Version 33.0.2, so I can't confirm this works on older versions. I had the same problem on my site. It looked the same in IE, Opera, Safari, and Chrome. It was only in Firefox I noticed the positioning different. This works!
