Template 'Decora'
How can I modify the header to more center-align the log and menu items. I do not see where to adjust this in the template UI. The logo is fixed at 25% and the mega-menu is fixed at 75%. Please advice if there is an easy way to do this or if I have to add the following;

sp-logo {

padding-left:5%;
}
.sp-megamenu-parent
{
float: none;
position: relative;
Margin-right: auto;
margin-left: auto;
width: 550px;
}
