I am just getting started using bootstrap. I need to position three input fields to form an “address” field.

I have tried using the following html:
<label for="street">Address</label>
<input class="span3" id="street" name="street" placeholder="Street"/><br/>

<input id="city" class="span2 inline" placeholder="City"/>

Try using the following:
