do you talk about backend, or about frontend?
at backend there is the wrapper attribute with class/id, use that to do whatever you need
at frontend you could do whatever you wish:
$your_field = get_field('your_field');
echo '<div class="something">'; //whatever you like to wrap around(pre) your field
echo $your_field; //your field value
echo '</div>'; //whatever you like to wrap around(after) your field
