Now, we can define styles for top level elements:
/* common and top level styles */
#navs span {
display: none;
}
#navs, #navs ul {
list-style: none outside none;
margin: 0;
padding: 0;
}
#navs {
background-color: #e34737;
border-bottom: 5px solid #e34737;
float: right;
margin-right: 1%;
margin-right: 1%;
position: relative;
width: 98%;
}
#navs ul.subs {
background-color: #FFFFFF;
box-shadow: 1px 1px 5px rgba(0, 0, 0, 0.2);
color: #333333;
display: none;
right: 0;
padding: 2%;
position: absolute;
top: 54px;
width: 96%;
}
#navs > li {
border-bottom: 5px solid transparent;
float: right;
margin-bottom: -5px;
text-align: right;
-moz-transition: all 300ms ease-in-out 0s;
-ms-transition: all 300ms ease-in-out 0s;
-o-transition: all 300ms ease-in-out 0s;
-webkit-transition: all 300ms ease-in-out 0s;
transition: all 300ms ease-in-out 0s;
}
#navs li a {
display: block;
text-decoration: none;
-moz-transition: color 450ms ease-in-out 0s, background-color 450ms ease-in-out 0s;
-ms-transition: color 450ms ease-in-out 0s, background-color 450ms ease-in-out 0s;
-o-transition: color 450ms ease-in-out 0s, background-color 450ms ease-in-out 0s;
-webkit-transition: color 450ms ease-in-out 0s, background-color 450ms ease-in-out 0s;
transition: color 450ms ease-in-out 0s, background-color 450ms ease-in-out 0s;
white-space: normal;
}
#navs > li > a {
color: #FFFFFF;
display: block;
font-size: 1em;
line-height: 45px;
padding: 0 10px;
text-transform: uppercase;
}
#navs > li:hover > a, #nav > a:hover {
background-color: #A52A2A;
color: #FFFFFF;
}


And now – styles for drop down (submenu):
/* submenu */
#navs li:hover ul.subs {
display: block;
}
#navs ul.subs > li {
display: inline-block;
float: none;
padding: 10px 1%;
vertical-align: top;
width: 33%;
}
#navs ul.subs > li a {
color: #777777;
line-height: 20px;
}
#navs ul li a:hover {
color: #F55856;
}
#navs ul.subs > li > a {
font-size: 1.3em;
margin-bottom: 10px;
text-transform: uppercase;
}
#navs ul.subs > li li {
float: none;
padding-right: 8px;
-moz-transition: padding 150ms ease-out 0s;
-ms-transition: padding 150ms ease-out 0s;
-o-transition: padding 150ms ease-out 0s;
-webkit-transition: padding 150ms ease-out 0s;
transition: padding 150ms ease-out 0s;
}
#navs ul.subs > li li:hover {
padding-right: 15px;
}

/* responsive rules */
@media all and (max-width : 980px) {
#navs > li {
float: none;
border-bottom: 0;
margin-bottom: 0;
}
#navs ul.subs {
position: relative;
top: 0;
}
#navs li:hover ul.subs {
display: none;
}
#navs li #s1:target + ul.subs,
#navs li #s2:target + ul.subs {
display: block;
}
#navs ul.subs > li {
display: block;
width: auto;
}
}
