slide in 'appears' and then navigates only a little

[wright67uk]

Below, I have set .navbar to animate after 4 seconds but I have a bit of a problem.

I want the navbar to slide down into view.

It seems that it's not animating from the top of the page.  It 'appears' and then animates on the last few pixels.

<style type="text/css">

        .navbar {

          display:none;

          min-height:auto;

        }

          width:100%!important;

          height:auto!important;

          visibility:hidden;

          z-index:-20;

        }

can anyone explain where i'm going wrong?

 

I can supply source code, but its a rather big file.

 

Many thanks.
