how do i change the height of this header ?

[WallBB]

Go to global.css in Theme and Templates> Focus Theme
And add this code at the bottom of the css file

Code:

#container {
padding-top: 100px;4
}
.header {
    height: 100px;
    line-height: 100px;
}

Change 100px to your liking
Make sure you have switched on development mode if you are using cloudfare else it is not required.
