CSS format for checkboxes - html

Question

I have a list of checkboxes, each one with a label:
<input type="checkbox" id="patient-birth_city" name="patient-birth_city" />
<label for="patient-birth_city">(_PATIENT_BIRTH_CITY_)</label>
<input type="checkbox" id="patient-birth_state" name="patient-birth_state" />
<label for="patient-birth_state">(_PATIENT_BIRTH_STATE_)</label>
<input type="checkbox" id="patient-birth_country" name="patient-birth_country" />
<label for="patient-birth_country">(_PATIENT_BIRTH_COUNTRY_)</label>
Without using any CSS they are showed in the same line (I suppose they have a default "inline" or "block-inline" display). The problem is I can't modify HTML structure and I need each pair checkbox-label appear in a new line. Like this. Is it possible using only CSS?

Answer 1

The good thing about label tags is you can wrap the input elements:
<label>
<input type="checkbox" id="birth_city" name="birth_city" />
City
</label>
<label>
<input type="checkbox" id="birth_state" name="birth_state" />
State
</label>
<label>
<input type="checkbox" id="birth_country" name="birth_country" />
Country
</label>
And if you add the following CSS:
label {
display: block;
}
It will display it how you want.

As you CAN'T edit your HTML, this CSS would work:
input, label {
float: left;
}
input {
clear: both;
}

Answer 2

Using float:left and clear:left you can do this with only css.
Demo: http://jsfiddle.net/VW529/2/
input {margin:3px;}
input, label {float:left;}
input {clear:left;}
The only problem is that the example does not show more information of parent elements, giving the container element overflow:hidden and/or clear:both might be needed to prevent floating elements next to the last label. (edited jsfiddle code with container div)
