This example came from the jQuery validation documentation. The required rule can be used to validate a required selection box when you set the value of the first option to empty.

The error message is the title since no error message is specified. A more fully defined validation check would look like this:
$('#my-form').validate({

This is an age old problem. Since it comes up time and time again, I'm writing this down for future reference. Let's start with a two-column layout generated by the 2 Column Layout Generator :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Trans... It renders like this: The left column is shorter than the right column. How to make the left and right column the same height? Adding height: 100% to the style sheet of the left column doesn't cut it. There are several hacks, none of them are straightforward: In search of the One True Layout Faux Columns Creating Liquid Layouts with Negative Margins In short, there's no instruction in CSS that tells a DIV that its height should be 100% of that of the...

If CSS3 border-image is properly supported, making a rounded corner box is very easy. You just need a round corner image like this: The following markup:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" ... would render like this (try it in Firefox 3.5 and Google Chrome): However, IE as of version 8.0 does not support border-image . So until border-image is reliably supported in all major browsers, we still have to rely on tried and true tricks to make it work. In general, I found three general categories of tricks to make rounded corners: Good old tables. This trick creates a table of 9 cells and uses the 8 cells on the perimeter to render the borders and rounded corners. The central cell is used for...

It seems that the key to aligning a checkbox with its label lies in the line-height property of the label. This simple HTML snippet aligns well:
<!DOCTYPE HTML> <html> <head> <style typ... which is rendered like this: Change the font size of the label to 12px throws off the alignment: label.checkbox { font-size: 12px; di... In case 1, the height of the checkbox is 13px with 3px top and bottom margin, for a total of 19px , which is exactly the height of the label div. As can be seen from Firebug : Checkbox layout Label layout In case 2, the height of the label div shrinks to 15px , while the height of the checkbox remains the same: Checkbox layout Label layout And...
