Hi,
Try adding this CSS code:
.site-header .container {
max-width: 100% !important;
width: 100% !important;
}
.site-header .top-section {
margin-left: -15px;
margin-right: -15px;
background-color: #ccc;
}
.site-header .top-section .row, .site-header .bottom-section {
margin-left: auto;
margin-right: auto;
}
@media only screen and (min-width: 768px) {
.site-header .top-section .row, .site-header .bottom-section {
max-width: 720px;
}
}
@media only screen and (min-width: 992px) {
.site-header .top-section .row, .site-header .bottom-section {
max-width: 960px;
}
}
@media only screen and (min-width: 1200px) {
.site-header .top-section .row, .site-header .bottom-section {
max-width: 1140px;
}
}
