Centering an <hr> tag

I'm having some trouble with my `hr` tag in HTML, as it isn't automatically centering as I expect it to. This is what my current code looks like: ``` <div id = "updatestatus" class = "statuscontainer"> <div class = "verticalalign">Update Status</div> </div> <hr width = "95%"> <div id = "insertstatus" class = "statuscontainer"> <form></form> </div> ``` As you can see, I'm placing my `hr` tag in between two `div`s, and I believe it's supposed to automatically center, but it ends up going to the left instead. I have also tried `hr align = center` with no success either. Edit: I just realized that when I place the entire `hr` tag within `<center></center>` it centers, but I'm still trying to figure out why it doesn't center on its own.
