Hi.
Not enough, just change Header height. Additionally, you need to change the line-height of the menu items and the height of the logo wrapper. And may be the height of logo image also should be changed.
#sp-header.header-sticky .logo {
height: 90px;
}
/* Optional*/
#sp-header.header-sticky .logo-image {
height: YOUR_VALUE !important;
}
/*--*/
#sp-header.header-sticky .sp-megamenu-parent > li > a,
#sp-header.header-sticky .sp-megamenu-parent > li > span {
line-height: 90px;
}
And also, I do not think that you need it for mobile, so the full code will look like this
@media (min-width: 992px) {
#sp-header.header-sticky {
height: 90px
}
#sp-header.header-sticky .logo {
height: 90px;
}
/* Optional*/
#sp-header.header-sticky .logo-image {
height: YOUR_VALUE !important;
}
/*--*/
#sp-header.header-sticky .sp-megamenu-parent > li > a,
#sp-header.header-sticky .sp-megamenu-parent > li > span {
line-height: 90px;
}
}
