my site **[Deliver](http://constantin-entertainment.info/deliveryservice)** .I have set the current menu color and hover colors respectively.the issue is when we scroll down the header is getting fixed at the bottom with a slight height change.so the menu colors are overlapping which i feel not good . so i tried in css 

```
.adjustsub nav ul li {
   height:40px !important;
   padding 0 0 0 0 ;
}

```

nothing seems to be working.Please help!!!

**EDIT
i need that in full height that of the header and when we scrolls down it should fit the fixed header size.reducing height doesn look good actualy**
