Reply To: Adjust height of main nav menu

@jamesandtina: If you are using Simple Catch Pro theme then you can add the following CSS in “Custom CSS” box in your Theme Options in WordPress Dashboard. You can decrease further by decreasing the number from 40px to further below.

#access ul li a {
line-height: 40px;
}
#access ul li ul {
top: 40px;
}
