In the custom.css you set up the code like this (change it to your preferred colours):
In this case the suffix is mobMeny (without any dot in front, the dot shall only be used in the css file not in the suffix, and it is a space before the mobMenu in the field Advanced settings/Module class-suffix in the module for the menu)
.mobMeny ul {
list-style: none inside !important;
width: 95%;
margin-top: 0 !important;
margin-bottom: 0 !important;
margin-left: auto !important;
margin-right: auto !important;
padding: 0;
}
/*#leftcol li {
border-bottom: 1px solid #DBCACB;
}*/
.mobMeny ul li {
padding-bottom: 0;
padding-left: 0;
}
.mobMeny li:first-child, .mobMeny li:first-child a {
border-top: 0;
border-top-left-radius: 10px;
border-top-right-radius: 10px;
}
.mobMeny li:last-child, .mobMeny li:last-child a {
border-bottom-left-radius: 10px;
border-bottom-right-radius: 10px;
margin-bottom: 10px;
}
.mobMeny li a:link, .mobMeny li a:visited {
background: #333;
height: 18px;
border-bottom: 1px solid #999;
padding: 1.2em 0 0.8em 1.5em;
color: #FFF;
display: block;
text-transform: uppercase;
text-decoration: none !important;
font-weight: 900 !important;
}
.mobMeny li a:hover {
background-color: #a1a1a1;
color: #FFFFFF;
}
