   Be aware that ‘is_admin()’ will return ‘false’ while in the theme customizer view, despite essentially being in the admin dashboard. To test for the customizer, use ‘is_customize_preview()’.

Example:

if ( ! is_admin() ) {
    // Runs only if this PHP code is in a file that displays outside the admin panels, like the theme template.
    echo '<div style="text-align: center">Welcome to our website.</div>';
} else {
    // Runs only if this code is in a file that displays inside the admin panels, like a plugin file.
    echo '<div style="text-align: center">Welcome to your Admin Panels.</div>';
}
