Bootstrap DatePicker CSS Styling not Working

Question

I am trying to use the datepicker from the datepicker site, but the CSS is not working as it should.

Here is my output and what I want it to look like:

Here's a jsFiddle here and the relevant code:

<div class="input-daterange">
  <input type="text" class="input" value="2012-04-05" />
  <span class="add-on">to</span>
  <input type="text" class="input" value="2012-04-19" />
  <button type="submit" class="btn btn-default" id='submit'>Submit</button>
</div>

But I can't tell what part of the css is being overridden to change the display of the datepicker.

Answer 1

The classes changed from Bootstrap 2 to Bootstrap 3

The date range markup in the docs is out of date for bootstrap 2:

<div class="input-daterange">
    <input type="text" class="input-small" />
    <span class="add-on">to</span>
    <input type="text" class="input-small" />
</div>

But if you go to the online demo with input ranges, you can see the correct markup:

<div class="input-daterange input-group">
    <input type="text" class="input-sm form-control" />
    <span class="input-group-addon">to</span>
    <input type="text" class="input-sm form-control" />
</div>

</div>
