Cannot get is_front_page to work

I have some code in my footer.php file that I only want activated on the home page. I am using a static front page, and the site is: https://stage.youth-spark.org/ The code I want activated only on the home page is:

<?php
				$display_brands_widget = false;
				if (isset($qode_options_flat['footer_brands_area'])){
					if ($qode_options_flat['footer_brands_area'] == "yes")  $display_brands_widget = true;
				}
				if($display_brands_widget): ?>
					<div class="carousel_slider_holder clearfix">
						<ul class="carousel_slider">
							<?php dynamic_sidebar( 'brands' ); ?>
						</ul>
					</div>
				<?php endif; ?>

I’m a total newbie at php, but have tried (what feels like) a dozen or so solutions from various sites, and nothing has worked. Any help is appreciated!
