Opera & page body margin

body { margin: 0px; }

In IE & Firefox there will be no margin for the page.
In Opera there is still the spacing. Why?

CSS2 specification suggests (see appendix A)

body { margin: 0px; padding: 8px; }

To have no spacing between page body & borders:

body { margin: 0px; padding: 0px; }

HOWTO: clear bash history?

JSCookMenu 1.4.3 Bug

File: JSCookMenu.js line 178
Old: hasChild = (item.length > 5);
New: hasChild = (item.length && item.length > 5);

Purpose: avoid warning because _cmSplit is parsed as an object and
does not have length property

Updated: JSCookMenu updated to 1.4.4 with a quick fix for a bug
for _cmSplit checking.

Firefox 1.5 returns “Warning: deprecated arguments usage”
Solution: “var argv = arguments;”
“The arguments object is a local variable available within all functions; arguments as a property of Function can no longer be used.”
