Position a div container on the right side - css

Question

I want to develop some kind of utility bar. I can position each element in this bar side by side using float:left;
But I want the second element to be positioned at the very right of the bar. This is hard for me because the width of the bar is not static.
Have a look at my demo: http://jsfiddle.net/x5vyC/2/
It should look like this:
Any idea how to achieve this using css?

Answer 1

Is this what you wanted? - http://jsfiddle.net/jomanlk/x5vyC/3/
Floats on both sides now
#wrapper{
background:red;
overflow:auto;
}
#c1{
float:left;
background:blue;
}
#c2{
background:green;
float:right;
}​
<div id="wrapper">
<div id="c1">con1</div>
<div id="c2">con2</div>
</div>​

Answer 2

Just wanna update this for beginners now you should definitly use flexbox to do that, it's more appropriate and work for responsive try this : http://jsfiddle.net/x5vyC/3957/
#wrapper{
display:flex;
justify-content:space-between;
background:red;
}
#c1{
background:blue;
}
#c2{
background:green;
}
<div id="wrapper">
<div id="c1">con1</div>
<div id="c2">con2</div>
</div>​

Answer 3

Use float: right to.. float the second column to the.. right.
Use overflow: hidden to clear the floats so that the background color I just put in will be visible.
Live Demo
#wrapper{
background:#000;
overflow: hidden
}
#c1 {
float:left;
background:red;
}
#c2 {
background:green;
float: right
}

Answer 4

if you don't want to use float
<div style="text-align:right; margin:0px auto 0px auto;">
<p> Hello </p>
</div>
<div style="">
<p> Hello </p>
</div>

Answer 5

I have one more solution other than float: right.
text-align: right;
padding: 10rem 3rem 2rem 3rem;
width: 58%;
align-items: end;
margin: 0px 0px 0px auto;
sometimes float does not work when we use width element for specific width at that time we can use the above code

Answer 6

This works for me.
<div style="position: relative;width:100%;">
<div style="position:absolute;left:0px;background-color:red;width:25%;height:100px;">
This will be on the left
</div>
<div style="position:absolute;right:0px;background-color:blue;width:25%;height:100px;">
This will be on the right
</div>
</div>
