How to use relative URL’s in WordPress

Normally Relative URL’s we use:
src(“/path/image.png”)

This method is not applicable to WordPress.
Use get_template_directory_uri() function in front of relative URL to work as same.
src(“<?php echo get_template_directory_uri() ?>/path/image.png”)

In some themes in wordpress, this may not work. Add the below code for its functioning:

path: wp-includes/theme.php

function get_template_directory_uri() {
    $template         = str_replace( '%2F', '/', rawurlencode( get_template() ) );
    $theme_root_uri   = get_theme_root_uri( $template );
    $template_dir_uri = "$theme_root_uri/$template";
 
    /**
     * Filters the active theme directory URI.
