I tried to make it more HTML 4.01 Transitional valid. Before changes validator noticed 56 errors. No should be better.
Changelog (index.php):
- some HTML properties changed into CSS style,
- deleted <b> tags from links because bold for "a" is define in CSS file,
- replaced four or more spaces with tabs,
- added \" marks into HTML properties,
- some missing close tags added,
- other trivial improvements.
Changelog (white.css):
- merged "pre" style properties,
- merged "select.selectbox" and "input.small" because styles are same,
- replaced four or more spaces with tabs,
- other trivial improvements.
