960 css `grid_9 align_right` not aligning to the right

Question

If you download the 960.css system and unzip it, you will find some demo files in the code directory.

If you rip out all the demo code and create the following simple HTML file,
you will note that the div with class instructions to take up 9 columns and align to the right does NOT align to the right, but to the left.

I LOVE 960.css - THANK YOU O GREAT AUTHOR. However, I would like to know why this one thing which I think should work is not working.

Answer 1

It turns out that align_right does not ship with 960.gs, so you have to add it manually:

.align_right {
 text-align: right;
}
