Two divs, one fixed width, the other, the rest

I've got two div containers.

Whilst one needs to be a specific width, I need to adjust it, so that, the other div takes up the rest of the space. Is there any way I can do this?

<div class="left"></div>
<div class="right"></div> <!-- needs to be 250px -->

.left {
    float: left;
    width: 83%;
    display: table-cell;
    vertical-align: middle;
    min-height: 50px;
    margin-right: 10px;
    overflow: auto;
}

.right {
    float: right;
    width: 16%;
    text-align: right;
    display: table-cell;
    vertical-align: middle;
    min-height: 50px;
    height: 100%;
    overflow: auto;
}

See: http://jsfiddle.net/SpSjL/ (adjust the browser's width)

HTML:

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

CSS:

.left {
    overflow: hidden;
    min-height: 50px;
    border: 2px dashed #f0f;
}

.right {
    float: right;
    width: 250px;
    min-height: 50px;
    margin-left: 10px;
    border: 2px dashed #00f;
}

You can also do it with display: table, which is usually a better approach: https://stackoverflow.com/questions/6938900/how-can-i-put-an-input-element-on-the-same-line-as-its-label/6938990#6938990

It's 2017 and the best way to do it is by using flexbox, which is IE10+ compatible.

.box {
  display: flex;
}

.left {
  flex: 1;  /* grow */
  border: 1px dashed #f0f;
}

.right {
  flex: 0 0 250px; /* do not grow, do not shrink, start at 250px */
  border: 1px dashed #00f;
}

<div class="box">
  <div class="left">Left</div>
  <div class="right">Right 250px</div>
</div>

You can use calc() Function of CSS.

Demo: http://jsfiddle.net/A8zLY/543/

<div class="left"></div>
<div class="right"></div>
 
.left {
height:200px;
width:calc(100% - 200px);
background:blue;
float:left;
}

.right {
width:200px;
height:200px;
background:red;
float:right;   
}

Hope this will help you!!

If you can flip the order in the source code, you can do it like this:

HTML:

<div class="right"></div> // needs to be 250px    
<div class="left"></div>

CSS:

.right {
  width: 250px;
  float: right;
}   

An example: http://jsfiddle.net/blineberry/VHcPT/

Add a container and you can do it with your current source code order and absolute positioning:

HTML:

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

CSS:

#container {
  /* set a width %, ems, px, whatever */
  position: relative;
}

.left {
  position: absolute;
  top: 0;
  left: 0;
  right: 250px;
}

.right {
  position: absolute;
  background: red;
  width: 250px;
  top: 0;
  right: 0;
}

Here, the .left div gets an implicitly set width from the top, left, and right styles that allows it to fill the remaining space in #container.

Example: http://jsfiddle.net/blineberry/VHcPT/3/

If you can wrap them in a container <div> you could use positioning to make the left <div> anchored at left:0;right:250px, see this demo. I'll say now that this will not work in IE6 as only one corner of a <div> can be absolutely positioned on a page (see here for full explanation).

1- Have a wrapper div, set the padding and margin as you like
2- Make the left side div the width you need and make it float left
3- Set the right side div margin equal to the left side width

.left
{
    ***width:300px;***
    float: left;
    overflow:hidden;
        
}

.right
{
    overflow: visible;
    ***margin-left:300px;***
}



<div class="wrapper">
    <div class="left">
        ...
    </div>

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

Hope this works for you!

There are quite a few ways to accomplish, negative margins is one of my favorites:

Good luck!

set your right to the specific width and float it, on your left just set the margin-right to 250px

.left {
vertical-align: middle;
min-height: 50px;
margin-right: 250px;
overflow: auto

}

.right {
width:250px;
text-align: right;
display: table-cell;
vertical-align: middle;
min-height: 50px;
height: 100%;
overflow: auto
}

If you need a cross browser solution, you can use my approach, clear and easy.

.left{
        position: absolute;
        height: 150px;
        width:150px;
        background: red;
        overflow: hidden;
        float:left;
}
.right{
        position:relative;
        height: 150px;
        width:100%;
        background: red;
        margin-left:150px;
        background: green;
        float:right;
}

Use the simple this can help you

<table width="100%">
    <tr>
         <td width="200">fix width</td>
         <td><div>ha ha, this is the rest!</div></td>
    </tr>
