two divs the same line, one dynamic width, one fixed_问答_开发者

I have two divs under one parent div, the parent div has 100% width:

<div id="parent">
  <div class="left"></div>
  <div class="right"></div>
</div>

The conditions are:

I want two divs on the same 开发者_高级运维line.
The right div may or may not be present. When it is present, I want it to always be fixed on the right. However, the left div must be elastic - it's width depends on its content.

I have tried both float:left, and dispaly:inline-block but neither solution seems to work.

Any suggestion would be appreciated.

I'd go with @sandeep's display: table-cell answer if you don't care about IE7.

Otherwise, here's an alternative, with one downside: the "right" div has to come first in the HTML.

See: http://jsfiddle.net/thirtydot/qLTMf/
and exactly the same, but with the "right div" removed: http://jsfiddle.net/thirtydot/qLTMf/1/

#parent {
    overflow: hidden;
    border: 1px solid red
}
.right {
    float: right;
    width: 100px;
    height: 100px;
    background: #888;
}
.left {
    overflow: hidden;
    height: 100px;
    background: #ccc
}
<div id="parent">
    <div class="right">right</div>
    <div class="left">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam semper porta sem, at ultrices ante interdum at. Donec condimentum euismod consequat. Ut viverra lorem pretium nisi malesuada a vehicula urna aliquet. Proin at ante nec neque commodo bibendum. Cras bibendum egestas lacus, nec ullamcorper augue varius eget.</div>
</div>

#parent{

    position:relative;
    display:table;

.left{

<div id="parent">

  <div class="right">fixed</div>
</div>

HTML:

<div id="parent">
  <div class="right"></div>
  <div class="left"></div>
</div>

(div.right needs to be before div.left in the HTML markup)

CSS:

.right {
float:right;
width:200px;
}

So left div style depends on the presence of right div. I can't think of a CSS selector allowing that kind of behavior yet.

Thus it seems to me that you'll need to programmatically add a class server side (or in JS) on parent div or left div to do that.

<div id="parent twocols">
  <div class="left"></div>
  <div class="right"></div>
</div>

<div id="parent">
  <div class="left"></div>
</div>

So right style is always :

.right {
    float: right;
    width: 200px; /* or whatever value you need */
    /* margin and padding at your discretion */
}

and left style is :

.parent.twocols .left {
    margin-right: 200px; /* according to right div width + margin + padding*/
}

I've had success with using white-space: nowrap; on the outer container, display: inline-block; on the inner containers, and then (in my case since I wanted the second one to word-wrap) white-space: normal; on the inner ones.

I think this is you want:

<html>
<head>
<style type="text/css">
#parent 
{width:100%;
height:100%;
border:1px solid red;
}
.left
{
float:left;
width:40%;
height:auto;
border:1px solid black;
}
.right
{
    float:left;

width:59%;
height:auto;
border:1px solid black;
}
</style>
</head>
<body>
<div id="parent">
  <div class="left">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

  <div class="right">This is the right side content</div>
</div>
</body>
</html>
