Add a Background Graphic to the Logo Area

Hi Sri Shunyata,

This is the code I use in my Storefront-child theme.

/* ******************************************************************* */
/* ***** style.css ***** */

/* Hide Site Title and Tagline */
.site-header .site-branding { display: none;}

/* To insert 10px above picture of header and (0px under main menu) */
.site-header {
padding-top: 10px;
padding-bottom: 0;
}

/* To get rid of the space above and below Cart */
a.cart-contents, .site-header-cart .widget_shopping_cart a {
padding: 0.0em 0 !important;
}

/* To get rid of the space above and below Main Menu */
@media screen and (min-width: 767px) {
.main-navigation ul.menu > li > a, .main-navigation ul.nav-menu > li > a {
padding-top: 0px;
padding-bottom: 0px;
}
}

/* ******************************************************************* */

/* ***** functions.php ***** */

/* Do not display Search in header */
add_action( ‘wp_enqueue_scripts’, ‘theme_name_parent_styles’ );
add_action( ‘init’, ‘jk_remove_storefront_header_search’ );
function jk_remove_storefront_header_search() {
remove_action( ‘storefront_header’, ‘storefront_product_search’, 40 );
}

/* APPEARENCE | CUSTOMIZE | HEADER */
/* No background image */
/* Background color: #fcf3de (SAME AS BOTH td in table below) */
/* Text color: #9aa0a7 */
/* Link colors: #96588a / Violet */
