View Full Version : IE8 and Firefox centring a inner div

12-19-2010, 05:04 PM
I am using FF and IE8 initially to test my site. In IE8 the content fills the whole of the page. But in FF it goes over to the left. So I thought I would centre the content. Except nothing is happening. Have I done it correctly? I made a div called holder to be centred. In IE8 nothing will happen but hopefully in FF it will be centred but it is not.

Relevant CSS

#left2 {width: 232px; float:left; display:inline;}
#right2 {width: 232px; float:left; display:inline;}
#center2 {width: 232px; float:left; display: inline; }
.holder {width: 100%; margin: 0 auto; display: inline; position: relative;}


<div class="textbox_outer">
<div class="textbox_inner">

Hello quartzy,
It's kind of hard to center a 100% width div. Put a temporary background color on that to see why.

To center an element you need three things:

a valid DocType
an element with a width
that elements right/left margins set to auto

///edit - looking closer I see it is an id in your markup - <div id="holder"> so .holder in your CSS should be #holder

I have all of the three you mentioned, so I will try again, perhaps I did think it a class.

width:100%; gives it nowhere to go. To center it, it would have to be less than full width.

#holder {
background: #f00;
overflow: auto;
width: 700px;
margin: 0 auto;
