Hello @bluekat,
Thanks for writing in!
Since you have your child theme active and ready, please follow the following steps below:
1] Using Notepad or TextEdit or Sublime Text or any text editor, please create a new file in your local machine.
2] Insert the following code into that new file
<?php
// =============================================================================
// VIEWS/GLOBAL/_BRAND.PHP
// -----------------------------------------------------------------------------
// Outputs the brand.
// =============================================================================
$option_logo_text = x_get_option( 'x_logo_text' );
$option_logo_src = x_get_option( 'x_logo' );
$logo_text = ( empty( $option_logo_text ) ) ? get_bloginfo( 'name' ) : $option_logo_text;
if ( empty( $option_logo_src ) ) {
$logo_output = $logo_text;
} else {
$logo_src = x_make_protocol_relative( $option_logo_src );
$logo_output = '<img src="' . $logo_src . '" alt="' . $logo_text . '">';
}
if ( x_get_option( 'x_logo_visually_hidden_h1' ) ) {
echo '<h1 class="visually-hidden">' . $logo_text . '</h1>';
}
?>
<a href="<?php echo home_url( '/' ); ?>" class="<?php x_brand_class(); ?> cs-hide-lg cs-hide-xl">
<?php echo $logo_output; ?>
</a>
<a href="<?php echo home_url( '/' ); ?>" class="<?php x_brand_class(); ?> cs-hide-md cs-hide-sm cs-hide-xs">
add another image here
</a>
3] Save the file named as _brand.php
4] Upload this file to your server in the child theme’s folder wp-content/themes/x-child/framework/legacy/cranium/headers/views/global/
The code above needs to be modification. You will have to insert your image as I have indicated with a text. That section will be displayed in larger screens and the current logo will be hidden.
Hope this helps.
