This is pretty useful in giving a visual indication to the user when a form field is required.
The CSS:
.form-group.required .control-label:after {
content:"*";
color:red;
}
Then in your HTML:
<form>
<div class="form-group required">
<label class="control-label">Required Field</label>
...
</div>
</form>
There will now be a nice little “*” after the label for “Required Field”.

thank you sooooooooo much
