Overlapping Border on Dropdown Menu - html

Question

I am trying to place a black border below the dropdown menu, then having the "selected" page which is currently the "Home" page being underlined using a orange border. I am trying to overlap the orange border on the black border.

Edited
Some people seems to be confused, I want to put the orange line on top of the black line.

Answer 1

you may need a lower boarder when you move?
#primary_nav_wrap ul li a:hover
{
color: #ff7500;
border-top: 4px solid #ff7500;/*add*/
}

Fixed

Added to html
<div class="clearBoth"></div>
<div id="top_blackline"></div>
Added to css
.clearBoth
{
clear:both;
}
#top_blackline
{
margin-top:-4px;
width: 100%;
border-bottom:4px solid #3a3a3a;
}

Answer 4

Just set the dark border on the first-level <li>s instead of <header>.
So the updated css code will look like this:
header {
position: absolute; /* removed border */
}
/* add the following rule */
#primary_nav_wrap > ul > li {
border-bottom:4px solid #3a3a3a;
}
which sets the dark border on first-level <li>s only using the direct child selector >, more on this selector here.
a preview of the code above is here.
