The good thing about tags labelis that you can wrap the elements input:
<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 as you want.
Demo here
HTML, CSS :
input, label {
float: left;
}
input {
clear: both;
}
