WHMCS WordPress Integration CSS Help

Hello,

Is there any instructions or examples of css to make the [wcp_menu] and [wcp_quick_nav] look better than we have here: http://www.webhostingjunkies.com/client-portal?whmcsportal%5Bpage%5D=aHR0cHM6Ly9tYW5hZ2VyLndlYmhvc3RpbmdqdW5raWVzLmNvbS9jbGllbnRhcmVhLnBocA%3D%3D

Here is the CSS we are using:

/* WHMCS Custom css*/

.whmcs_error {

border-radius: 3px;

border: 1px solid #FF0000;

background-color: #FFBCBC;

padding: 5px 10px;

margin: 5px 0px 10px;

font-size: 1.2em;

}

ul

{

list-style-type:none;

margin:0;

padding:0;

}

li

{

float:left;

}

{

background-color:#7A991A;

}

li

{

display:inline;

}

</style>

Any help is greatly appreciated. Now that we got it running finally we want to make it look pretty. Thanks in advance.
