Initial addition of a `details` and `summary` test to the demo.
These are new HTML5 elements and there is not yet widespread
browser implementation of their interactive functionality.
Remove the default padding. In theory, the correct normalization
would be to add the padding to IE6/7 rather than remove it from
all browsers. However, the most common use case is going to be
for legends within unstyled fieldsets, and the presence of 2px
of horizontal padding is likely to be unexpected.
Allow text wrapping in Firefox 3. Modify the default white-space
value to allow long legends to wrap. No simple fix to allow this
in IE6/7/8.
Applying *overflow:visible to button/input causes text inputs to
grow to fit their content, even if an explicit, fixed width is
applied. It was originally included to remove excess inner
spacing on buttons and submit/reset/button-type inputs in IE6/7.
Fixing this bug in IE6 requires dropping the fix entirely because
there is no way to avoid it being applied to text inputs. If
there is a need to fix this excess spacing bug in IE6, then it
should be done using a class that is applied to the
necessary elements.
For IE7, the excess spacing fix can be moved into the ruleset
that targets button and submit/reset/button-type inputs. This
prevents text inputs from growing.
