CSS: display:inline-block and positioning:absolute
Please consider the following code:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
<style type="text/css">
.section {
display: block;
width: 200px;
border: 1px dashed blue;
margin-bottom: 10px;
}
.element-left,
.element-right-a,
.element-right-b {
display: inline-block;
background-color: #ccc;
vertical-align: top;
}
.element-right-a,
.element-right-b {
max-width: 100px;
}
.element-right-b {
position: absolute;
left: 100px;
}
</style>
<title>test</title>
</head>
<body>
<div class="section">
<span class="element-left">some text</span>
<span class="element-right-a">some text</span>
</div>
<div class="section">
<span class="element-left">some text</span>
<span class="element-right-a">some more text to force line wrapping</span>
</div>
<div class="section">
<span class="element-left">some text</span>
<span class="element-right-b">some text</span>
</div>
<div class="section">
<span class="element-left">some text</span>
<span class="element-right-b">some more text to force line wrapping</span>
</div>
<div class="section">
<span class="element-left">some text</span>
<span class="element-right-b">some more text to force line wrapping</span>
</div>
</body>
</html>
The element with absolute positioning apparantly makes the containing box "forget" which height he needs.
I need the absolute positioning inside the "section" box, is there another solution for this?
thanks in advance, geronimo
edit
Using tables is not really an option, I need some sort of "multi-level"/"nested" layout, where the second col is always on the same position:
| some text in first column | some text in 2nd column
| some indented text | 2nd column
| also indented | 2nd col
| even more indent | 2nd column with a lot of text that
| makes it wrap
| text | ...
| blah blah | ...
(of course whithout the "|"s)
Answer
When you use position:absolute;, the element is taken out of the normal page flow. Therefore it no longer affects the layout of its container element. So the container element does not take into account its height, so if there's nothing else to set the height, then the container will be zero height.
Additionally, setting display:inline-block; does not make any sense for an element that is position:absolute;. Again, this is because absolute positioning takes the element out of the page flow. This is at odds with inline-block, which only exists to affect how the element fits into the page flow. All elements that are position:absolute; are automatically treated as display:block, since that's the only logical display mode for absolute positioning.
If you need absolute positioning, then the only solution to your height problem is to set the height of the container box.
However, I suspect that you could do without the absolute positioning.
It looks like what you're trying to do is position the second <span> in each block to a fixed position in the block, so that they line up.
This is a classic CSS problem. In the "bad-old-days", web designers would have done it using a table, with fixed widths on the table cells. This obviously isn't the answer for today's web designers, but it is something that causes a lot of questions.
There are a number of ways to do it using CSS.
The easiest is to set both the <span> elements to display:inline-block;, and give them both a fixed width.
eg:
<div class='section'>
<span class="element-left">some text</span>
<span class="element-right">some text</span>
</div>
with the following CSS:
.section span {display:inline-block;}
.element-left {width:200px;}
.element-right {width:150px;}
[EDIT]after question has been updated
Here's how I would achieve what you're asking now:
<div class='section'>
<span class="element-left"><span class='indent-0'>some text</span></span>
<span class="element-right">some text</span>
</div>
<div class='section'>
<span class="element-left"><span class='indent-1'>some text</span></span>
<span class="element-right">some text</span>
</div>
<div class='section'>
<span class="element-left"><span class='indent-2'>some text</span></span>
<span class="element-right">some text</span>
</div>
with the following CSS:
.section span {display:inline-block;}
.element-left {width:200px;}
.indent-1 {padding:10px;}
.indent-2 {padding:20px;}
.element-right {width:150px;}
A small amount of extra markup, but it does achieve the effect you want.
