The hight of the Cathegory menu and the opacity

Hello,
1. How can I change the height of the Category menu (make it thinner) and change it's opacity (of the background - white) colour or make it fully transparent?
2. How can I change the opacity of the white Blog background or make it fully transparent?
Thank you!

 

Hello,

1. Paste the following code in your Custom CSS
(Appearance -> Theme Options -> Styling Options -> Custom CSS)

Code:

#menu .ddsmoothmenu li a {
padding-top: 5px ! important;
padding-bottom: 5px ! important;
}
#menu .ddsmoothmenu li:first-child a{
background-position-y: 5px;
}
#menu .ddsmoothmenu {
line-height: 28px;
}
#menu {
background: transparent;
}

This will solve your first issue.

2. Paste the following code in your Custom CSS
