Required marker within input

I like this placement of the required field marker on the KISSmetrics blog. It’s clever, displayed with a CSS background image on the input element.

A word of warning though, there should be some way to distinguishing this field as required even when styles are disabled.

Unfortunately this form doesn’t provide any fallback if you don’t have styles enabled. A simple span with “Required” with a display: none next to the input would suffice. But regardless of its shortcomings, I love this little UI scrap!
