padding-top: 75px;
padding-bottom: 75px;
}
aside.mythemes-header-items div.header-item > div.widget{
margin-top: 60px;
margin-bottom: 0px;
margin-left: 0px;
margin-right: 0px;
}
aside.mythemes-header-items div.header-item > div.widget:first-child{
margin-top: 0px;
}
@media (max-width: 991px){
aside.mythemes-header-items div.header-item:last-child{
margin-top: 60px;
}
}
@media (max-width: 767px){
aside.mythemes-header-items div.header-item{
margin-top: 60px;
}
aside.mythemes-header-items div.header-item:first-child{
margin-top: 0px;
}
}
75px – is top and bottom space between content and start / end of white area.
60px – is space between widgets and sidebars ( if exists multiple or for small devices ).
just replace values 75 and 60 with yours values for example 45 and 25.
