If you want to make your LiveEditor page header look a similar height to the SmartTheme header, you can use the following code:
.banner{
height:100px;
padding:0px;
}
.banner .op-logo {
max-height: 50px;
height: 50px;
padding-top: 25px;
}
.banner .op-logo img{
padding:0px;
max-height:50px;}
This code would be added inside OptimizePress > Page Settings > Other Scripts > Custom CSS
