When dotted borders are specified as the border-style, and the border??™s width is
only 1px, Internet Explorer for Windows versions up to and including 6 will display
the borders as dashed instead of dotted. At a width of 2px and above, the dotted
borders will display correctly. This glitch was fixed in Internet Explorer Version 7
The Ultimate CSS Reference 224
for cases when all four sides are set to 1px. However, if one of the sides is set to 2px
or more, the 1px dotted borders revert to dashed in IE7.
The appearance of the borders may vary between user agents (within limits). The
algorithms that define the relationship between the colors used to achieve an effect
(for example, groove, ridge, inset, and outset) are not explicitly defined in the
CSS specifications, so the colors may vary between user agents. In CSS2.1, the
three-dimensional border styles (groove, ridge, inset, and outset) depend on the
corresponding border-color, rather than on color.
Internet Explorer for Windows versions up to and including 7:
?– don??™t support the value hidden
?– don??™t support the value inherit
border-top-width
border-top-width: { thin | medium | thick | length
| inherit } ;
The property border-top-width sets
the width of the border to the top side
of an element using the values specified.
