help present the proper state of the elements.
By default, labels and forms are inline elements. This is a useful baseline,
but creating a form presentation with a clean grid requires some changes
to those default behaviors and sometimes a little extra markup or careful
use of fieldset elements.
Creating a layout where the label is on a line above the form field is as
easy as setting the label to display as a block element would ( Figure 11.4 ):
<label for="fname">First Name:</label>
