Question

I got a following set up using the lastest twitter bootstrap framework:

http://jsfiddle.net/hfexR/2/

I now want that the input field takes the maximum width when there is no button next to.

How can I do this with pure css or with twitter-bootstrap itself?

Something like inline-block should go, I just don’t get it at the moment…

EDIT : since bootstrap v3, classes have evolved so use col-xx-X classes to obtain the result explained below (further changes may be necessary)

Live demo (jsfiddle)

You could use a .row-fluid and use .spanX to make the inputs fill their container :

<form class="form-search">
  <div class="row-fluid">
      <input type="text" class="input-medium search-query span12">
  </div>
</form>
<form class="form-search">
  <div class="row-fluid">
      <input type="text" class="input-medium search-query span8">
      <button type="submit" class="btn span4">Cancel</button>
  </div>
</form>

It appears that a little fix is needed for the button/input combination :

/* May not be the best way, not sure if BS has a better solution */
/* Fix for combining input and button spans in a row */
.row-fluid > input + button[class*="span"] {
    float: none;           /* Remove the */
    display: inline-block; /* floating   */
    margin-left: 0;        /* Stick it to the left */
}

Last thing, you shouldn’t combine .spanX and .well because of the padding and borders and other things, here is an example of why (jsfiddle).
