#sectionhead{
height:124px;
}

But if you need to change the color, the doc needs this:

#sectionhead{
height:124px;
}


#wlcontent{
border-left: #33414e 3px solid;
border-right: #33414e 3px solid;
border-bottom: #33414e 3px solid;
}

.wlnavigation {
border-left: #33414e 3px solid;
border-right: #33414e 3px solid;
border-bottom: #33414e 0px solid;
}
