how to evenly space layers within a container layer
I have a container layer with a width of 850px. Inside of that i have 4 layers displayed as inline-blocks floating left, each of which are 100px high and 200px wide.
How can i space them so the outside ones line up at the edges of the container div but are spaced evenly within?
css
#content {
width: 850px;
margin-right: auto;
margin-left: auto;
}
#featured {
display: inline-block;
height: 100px;
width: 200px;
float: left;
margin-left: 10px;
margin-top: 10px;

html
<div id=content>
<div id=featured></div>
<div id=featured></div>
<div id=featured></div>
<div id=featured></div>
</div>
It's not really going to work, because you have a container that's 850px wide and you're trying to spread 4 200px wide containers with three gutters between them. 4*200 = 800 so you have 50px spread in which to split 3 gutters 50/3 is 16.6666ish which isn't going to work for pixels.
The following works, but I don't know how useful it is for you.
#content {
width: 848px;
margin-right: auto;
margin-left: auto;
background: #666;
overflow: hidden;
}
#featured {
display: inline-block;
height: 100px;
width: 200px;
float: left;
margin-left: 16px;
margin-top: 10px;
background-color: #09F;
}
#featured.first { margin-left: 0px;}
<div id=content>
<div id=featured class="first"></div>
<div id=featured></div>
<div id=featured></div>
<div id=featured></div>
</div>
There are a couple of ways to do this. One cross-browser solution I have found is to use an extra wrapper div and get creative with it's true dimensions and negative margins.
<div id="content">
<div class="kludge">
<div class="featured"></div>
<div class="featured"></div>
<div class="featured"></div>
<div class="featured"></div>
</div>
</div>
I changed id=featured to a class name because ids should be unique if you want your HTML to be valid.
The CSS:
#content {
width: 850px;
margin: 0 auto; /* short-hand for margin, first value is top+bottom, second value is left+right */
overflow: hidden; /* not actually necessary but will make #container contain the floated items */
}
.kludge {
width: 900px; /* create room for the right hand margin of last item */
margin-right: -50px;
}
.featured {
display: block; /* inline-block not necessary for floated elements */
height: 100px;
width: 200px;
float: left;
margin: 0 10px;
background-color: #09F;
}
I think the easiest way is:
<style>
#content {
width: 850px;
margin-right: auto;
margin-left: auto;
border:1px solid #000
}
#featured1 {
display: inline-block;
height: 100px;
width: 200px;
float: left;
margin-left: 0px;
margin-top: 10px;
background-color: #09F;
}
#featured2 {
display: inline-block;
height: 100px;
width: 200px;
float: left;
margin-left: 16px;
margin-top: 10px;
background-color: #09F;
}
</style>
</head>
<body>
<div id=content>
<div id=featured1></div>
<div id=featured2></div>
<div id=featured2></div>
<div id=featured2></div>
</div>
Maybe not what you need, but If IE6 support is not important pseudo selectors are perfect for this, and avoid any HTML fudges (tested in IE7, FF3.5):
CSS:
#content {
width: 848px;
margin: 0 auto;
overflow: auto;
}
.featured {
height: 100px;
width: 200px;
float: left;
margin-left: 16px;
margin-top: 10px;
background-color: #09F;
}
.featured:first-child {
margin-left: 0;
}
HTML:
<div id="content">
<div class="featured"></div>
<div class="featured"></div>
<div class="featured"></div>
<div class="featured"></div>
</div>
