Perfect 100% width of parent container for a Bootstrap input?

Applying the input-block-level class works great for me, across various screen widths. It is defined by Bootstrap in mixins.less as follows:

// Block level inputs
.input-block-level {
  display: block;
  width: 100%;
  min-height: 28px;        // Make inputs at least the height of their button counterpart
  .box-sizing(border-box); // Makes inputs behave like true block-level elements
}

This is very similar to the style suggested by 'assembler' in his comment on issue #1058.


Just add box-sizing:

input[type="text"] {
    box-sizing: border-box;
}

For anyone Googling this, one suggestion is to remove all the input-group class instances. Worked for me in a similar situation. Original code: 

<form>
  <div class="bs-callout">
    <div class="row">
      <div class="col-md-4">
        <div class="form-group">
          <div class="input-group">
            <input type="text" class="form-control" name="time" placeholder="Time">
          </div>
        </div>
      </div>
      <div class="col-md-8">
        <div class="form-group">
          <div class="input-group">
            <select name="dtarea" class="form-control">
              <option value="1">Option value 1</option>
            </select>
          </div>
        </div>
      </div>
    </div>
    <div class="row">
      <div class="input-group">
        <input type="text" name="reason" class="form-control" placeholder="Reason">
      </div>
    </div>
  </div>
</form>
With input-group

New code:

<form>
  <div class="bs-callout">
    <div class="row">
      <div class="col-md-4">
        <div class="form-group">
          <input type="text" class="form-control" name="time" placeholder="Time">
        </div>
      </div>
      <div class="col-md-8">
        <div class="form-group">
          <select name="dtarea" class="form-control">
            <option value="1">Option value 1</option>
          </select>
        </div>
      </div>
    </div>
    <div class="row">
      <input type="text" name="reason" class="form-control" placeholder="Reason">
    </div>
  </div>
</form>
Without input-group

If you're using C# ASP.NET MVC's default template you may find that site.css overrides some of Bootstraps styles. If you want to use Bootstrap, as I did, having M$ override this (without your knowledge) can be a source of great frustration! Feel free to remove any of the unwanted styles...

/* Set width on the form input elements since they're 100% wide by default */
input,
select,
textarea {
    max-width: 280px;
}
