Fixed width div on right, fill remaining width div on left [duplicate]

Question

Im searching for a way to have 2 divs as columns where div on right has a fixed width and div on left fill remaining space.

Does anyone happen to know if this can be done?

My attempt (renders block2 underneath block1):

<style>
.block1 {
   width: auto;
   height: 200px;

   background-color: green;
}
.block2 {
   float: right;
   height: 200px;
   width: 200px;

   background-color: red;
}
</style>

<div class="block1">test1</div>
<div class="block2">test2</div>

Answer 1

You can do it like this:

HTML:

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

CSS:

.left{
    background:red;

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

Answer 2

Float Both of the elements left:

<style>
.block1 {
   width: auto;
   height: 200px;
   float: left;
   background-color: green;
}
.block2 {
   float: left;
   height: 200px;
   width: 200px;

   background-color: red;
}
</style>

<div class="block1">test1</div>
<div class="block2">test2</div>

You should wrap them in a container as well to prevent messing up the rest of your layout. :)

That was wrong!

Use display: table; on parent and display: table-cell; on children:

<div id="wrapper">
    <div class="block1">test1</div>
    <div class="block2">test2</div>
</div>


#wrapper
{
    display: table;
    width: 100%;
}

.block1 {
       width: auto;
       height: 200px;
       display: table-cell;
       background-color: green;
}
.block2 {
       display: table-cell;
       height: 200px;
       width: 200px;
       background-color: red;
    }
