#1 Background color from themes settings

This example shows how to add a top border for the footer block with the same color as the background color set in the settings.

You can insert the code at the beginning of header.php

<style>
.footer {
	 border-top: solid 1px #<?= get_theme_mod('background_color') ?>;
}
</style>
0

#2 Background color with a default value

Sometimes you need to set default value for avoid any bad situation. This example could be used to add the custom background color for the .footer block:

.footer {
	 background: #<?= get_theme_mod( 'background_color', '#fff' ) ?>;
}

#3 Recommended to escape value with proper escaping function

.search-bar {
	background-color: <?= esc_html( get_theme_mod( 'talash_background_color', '#000' ) ) ?>;
}
<a href="<?= esc_url( get_theme_mod( 'talash_url' ) ); ?>">
