This content is marked source of information.

Custom logo can be used in dynamic top navigation bars or other places within theme. Add a support for setting custom logo using WordPress built-in function from the backend.

• Add custom logo support
• Set the logo
• Print the custom logo

Step 1: Add custom logo support using add_theme_support function in functions.php of child theme or parent or where needed.

add_theme_support( 'custom-logo');

Step 2: Set the logo in the backend or let the user set it.

1. Go to the Admin Dashboard > Appearance > Customizer > Site Identity
2. Set the logo image

Step 3: Print the logo on frontend

There are two ways to print custom logo on frontend of website.

Method 1: With markup

Just use the_custom_logo() function to print logo image with img markup. No need of echo since it already echos the markup directly.

<?php the_custom_logo(); ?>

Method 2: Without markup, just get the source

If you have defined your custom logo image markup already, read ‘WP get custom logo image URL‘ guide. It’ll also help you to get the custom logo URL or source in different custom image sizes.
