Hello There,
The h1 is coming from the _brand.php
file which is set in the theme by default.
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.
// =============================================================================
$site_name = get_bloginfo( 'name' );
$site_description = get_bloginfo( 'description' );
$logo = x_make_protocol_relative( x_get_option( 'x_logo' ) );
$site_logo = '<img src="' . $logo . '" alt="' . $site_description . '">';
?>
<a href="<?php echo home_url( '/' ); ?>" class="<?php x_brand_class(); ?>" title="<?php echo $site_description; ?>">
<?php echo ( $logo == '' ) ? $site_name : $site_logo; ?>
</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/
You will need to create the folder path since it does not exist in your child theme yet.
Please let us know how it goes.
