Vanilla fieldset with legends
Basic form elements other than fieldset/legend have been styled and the form has a background for debugging. IE and FF are the most broken.
Fieldset with basic legend styling to mimic display: block
Identical to above, except it has basic display: block imitation styling and CSS reset is in place.
A classier example
Because HTML+CSS example pages are always so freaking hideous and I like to break the mold.
