How do I left align these Bootstrap form items?

I'm using Bootstrap for the first time, and am having a lot of trouble aligning this form-horizontal to the left.

The list items are horizontal, as they should be, but I want the control-labels (the Bootstrap class for form labels) to all be at the same position floated left.

The form is contained in a div with a span of 7, as my site is two columns -- 7 and 4 columns.

Below is my HTML. If you look under "Horizontal Forms" on this page http://accounts.tao.tw.shuttle.com/examples_bootstrap/basecss/forms, you'll see that the labels are left aligned, but not absolutely left-aligned so that the beginning of the labels are at the same position vertically.

<form class="form-horizontal">
    <div class="control-group">
        <label class="control-label" for="inputSaving">What are you saving for?</label>
        <div class="controls">
            <input class="span4" type="text" id="inputSaving" placeholder="e.g. Swimming Lessons, Birthday Party, College Fund, etc.">
        </div>
    </div>
    <div class="control-group">
        <label class="control-label" for="description">Add a short description</label>
        <div class="controls">
            <textarea class="span4" rows="4" placeholder="Describe in your own words the saving goal for this piggybank"></textarea>
        </div>
    </div>
    <div class="control-group">
        <label class="control-label" for="categoryselect">Choose a Category</label>
        <div class="controls">
            <select class="span4">
                <!-- Add some CSS and JS to make a placeholder value-->
                <option value="Kittens">Kittens</option>
                <option value="Keyboard Cat">Keyboard Cat</option>
                <option value="Twitter Bird">Twitter Bird</option>
            </select>
        </div>
    </div>
    <div class="control-group">
        <label class="control-label" for="goal">Your Saving Goal</label>
        <div class="controls">
            <input type="text" class="span4" id="goal">
        </div>
    </div>
    <button class="btn btn-large btn-primary" type="button">Submit</button>
</form>

Just my two cents. If you are using Bootstrap 3 then I would just add an extra style into your own site's stylesheet which controls the text-left style of the control-label.

If you were to add text-left to the label, by default there is another style which overrides this .form-horizontal .control-label. So if you add:

.form-horizontal .control-label.text-left{
    text-align: left;
}

Then the built in text-left style is applied to the label correctly.

If you are saying that your problem is how to left align the form labels, see if this helps:

Try changing the text-align left / right in the CSS

.form-horizontal .control-label{
    /* text-align:right; */
    text-align:left;
    background-color:#ffa;
}

Instead of altering the original bootstrap css class create a new css file that will override the default style.

Make sure you include the new css file after including the bootstrap.css file.

In the new css file do

.form-horizontal .control-label{
   text-align:left !important; 
}

"pull-left" is what you need, it looks like you are using Bootstrap 2, I am not sure if that is available, consider bootstrap 3, unless ofcourse it is a huge rework! ... for Bootstrap 3 but you need to make sure you have 12 columns in each row as well, otherwise you will have issues.

Just add style="text-align: left" to your label.
