Problem in Breadcrumb nevigation

[pralay]

Hi,
I have added the breadcrumb nevigation....but by default it is taking an underline below the link ...i want to edit the css of the breadcrumb link so that text color become different and there is no underline.
How should I do that?

I have added css like
.a:link{
.....
}
.a:hover{
.....
}
in one of attached css file.
But with no effect.
Please help me.
It's urgent.

You would need to call the breadcrumb first...

.breadcrumbs a {your styling}
.breadcrumbs a:hover {your style}
