Change the footer text

Hi

I have been using WordPress and Storefront for about 2 weeks now and I have nearly got the design I like.

There are a couple of things I would like to customise. I would like to change the size of the text and the links within Storefront. I have a basic child theme which I have created.

There are 4 regions on the footer, region 1 to 3 have links and the 4th region I will be using for social media links.

My css looks like:
‘/*
Theme Name: Storefront-Child
Description: This is my personal CSS file
Version: 1.0.0 Alpha release
Author: Tankman15
Parent: storefront
*/

/* Remove the site name from the header.
————————————————————– */
.site-branding h1, .site-branding .site-description {
visibility: hidden; display: none;
}

/* Set the global font to used (Tahoma).
————————————————————– */
html * {
font-family: Tahoma, Geneva, sans-serif;!important
}

/* Set the global headings.
————————————————————– */
h1 {
text-transform: capitalize;
text-align: center;
}
h2 {text-transform: capitalize;}
h3 {text-transform: capitalize;}

/* Set footer text.
————————————————————– */
.widget-area .widget {
color: red;
font-size: 10px;
}’

My functions.php looks like:
‘<?php

// Import Storefront Styles
add_action( ‘wp_enqueue_scripts’, ‘enqueue_parent_theme_style’ );
function enqueue_parent_theme_style() {
wp_enqueue_style( ‘parent-style’, get_template_directory_uri().’/style.css’ );
}

// Remove WooThemes Credit from Footer
add_action( ‘init’, ‘custom_remove_footer_credit’, 10 );
function custom_remove_footer_credit () {
remove_action( ‘storefront_footer’, ‘storefront_credit’, 20 );
add_action( ‘storefront_footer’, ‘custom_storefront_credit’, 20 );
}
function custom_storefront_credit() {
?>
<div class=”site-info”>
© <?php echo get_bloginfo( ‘name’ ) . ‘ ‘ . get_the_date( ‘Y’ ); ?>
</div><!– .site-info –>
<?php
}

// Remove search bar from the header.
add_action( ‘init’, ‘jk_remove_storefront_header_search’ );
function jk_remove_storefront_header_search() {
remove_action( ‘storefront_header’, ‘storefront_product_search’, 40 );
}
?>/’

But this doesn’t change my text size. Does anyone know how to change my text and the links within the footer (region 1 to 3)?

Thank you in advance.
