Question

I have following HTML snippet:

<div id="container">
  <div id="left">Left block</div>

  <input type="text" />

  <div id="right">Some longer than 200px text</div>
</div>

And CSS:

#container {
  width: 100%;
}
#left {
  width: 200px;
  float: left;
  border: 1px solid black;
}
#right {
  min-width: 200px;
  float: right;
  border: 1px solid black;
}
input {
  float: left;
}

Is it possible to set input to has all free space width ? I mean it should starts with #left right border and ends with #right left border.

<div id="container">
    <div id="left">Left block</div>
    <div id="right">Some longer than 200px text</div>
    <span><input type="text" value="hello" /></span>
</div>

​#container span {
    display: block;
    overflow: hidden;
    border: 1px solid red;
}
#container span input {
    width: 100%;
    -webkit-box-sizing: border-box;
       -moz-box-sizing: border-box;
            box-sizing: border-box;
}​

#container {
  width: 100%;
}
#left {
  width: 200px;
  float: left;
  border: 1px solid black;
}
#right {
  min-width: 200px;
  float: right;
  border: 1px solid black;
}
