HTML 4.01 in Netscape and Explorer: Alignment, Font Styles, and Horizontal Rules

Alignment, Font Styles, and Horizontal Rules
Ye goode olde way

All the elements and attributes described in this section of the specification are supported by both Netscape and Explorer, with only a couple of changes:

Table cells, as described in the section on tables, do not accept an attribute value of align=justify.

Explorer recognizes a color attribute to the hr element that gives a color for the horizontal rule, which is especially handy for pages with black backgrounds, which usually render rules invisible.
