I like the CSS bottom blue border between posts. Vbulletin’s I’ve visited in the past do not have this…how is it done and why does the size of the border vary by the post?

I asked the same question about the thickness. Nobody seemed to know why some were thicker and some were thinner than others–just a random thing. You can even reload a thread later, and the borders will be different. Weird, eh?

But the freaky thing is, if you double click the border, it will go back to the full size. Wow!

It’s been reported before, and you can get the colored portion of the divider to vary in size by scrolling in odd ways. Here’s an old [post=4568930]post[/post] that describes a strange effect you can get with the IE scroll cursor.

It’s a bug in MSIE. Switch to Firefox and the borders always stay the same size.
