Problems don't know where to start

Hi

The logo, graphics, colours etc are set through the customizing panel. There is no where to set the size of the logo, and looking at the code it doesn’t show there either.

Sorry I’m not a coder,I can look at it and try to work out what it is supposed to do, but apart from that I’m a complete novice.

If this helps, this is the content of functions.php

<?php
/**
 * Adds the individual sections, settings, and controls to the theme customizer

function example_customizer( $wp_customize ) {
    $wp_customize->add_section(
