clear

I have this function function smth() { var container = null; var newContainer = null; if (window.getSelection) { // all browsers, except IE before version 9 alert("first if"); var selectionRange = window.getSelection(); if (selectionRange.rangeCount > 0) { var range = selectionRange.getRangeAt(0); container = range.commonAncestorContainer; newContainer = container; } } else { if (document.selection) { // Internet Explorer alert("second if"); var textRange = document.selection.createRange(); container = textRange.parentElement(); } } if (newContainer) { return newContainer.nodeName; } else {

Using Java (1.6) is it better to call the clear() method on a List or just re-instantiate the reference?

I'm trying to make a box with rounded corners where the height and width of the div depends on the content, so it's automatically adjust to it... You can see the example here: http://pastehtml.com/view/1duizyf.html The problem is that i can't get the "test_mid_left" (black background) and "test_mid_right" (turquoise background) to inherit the height from the "test_mid_center" (green background). I have tried height: 100% and auto, but none of thoose work. So how do I get them to inherit the height from the content? (The reason why I have used "min-height: xx" in the left and right content on
