Browser Peculiarities
Internet Explorer
4.0:
- Of the various form field types, Padding properties are only applied to
button widgets (Input Type=Submit|Reset|Button.)
- Padding applied to TABLE elements applies to the individual cells, not
the table structure.
4.0+:
- Using Padding properties on a form button widget
(Input Type=Submit|Reset|Button) applies the padding inside the button,
not outside the button.
- Padding properties do not apply to images
4.0-5.0:
- This property does not apply to inline elements.
5.0+:
- Padding applied to TABLE elements has SOME effect on cell
content, but it is difficult to identify patterns to the behavior.
- Padding now applies to text entry fields as well (Input
Type="File|Text", Textarea), but as with button widgets, the padding
is applied inside the field, not outside it.
5.5+:
- Beginning in 5.5 Beta 1, this property now applies to inline elements.
Netscape
4.x:
- Positive padding values on inline elements appears to be very broken
(negative or zero values are ignored.) I am sure there is probably a rational
heuristic at work deciding what to do with the content, but in most cases the
result is badly overlapping content. Stay away from this in Netscape.
- Applying padding values to a replaced object (my test was an IMG element)
really messes with document content flow.
- Padding applied to individual List Items (LI) causes the list marker
to NOT be rendered. If applied to a list structure (OL, UL, etc) the list
markers are rendered.
- Padding applied to TABLE elements applies to the individual cells, not the table structure.
- Some situations involving padding properties can cause extra line feeds when printing.
Opera
3.5:
- Padding is not applied to replaced items (IMG, form field widgets, etc.)
- Padding-top and Padding-bottom values are ignored for inline elements
(EM, STRONG, SPAN, etc.) Only Padding-left and Padding-right values
are honored for spacing. The surface color for the padding, however,
DOES cover any specified Padding-top and Padding-bottom values.
- Padding applied to TABLE elements has odd effects. No effect on TD/TH.
