Change color of header bar

add this to your css

.site-header {
background: #fff; !important;
}

but then the links will be white colour so you have to change the color of the links. if you want black links and white header then add this

.site-header {
background: #fff; !important;
}

.main-navigation li a {
color: #000;
}

Thank you so much!

no problem ??
