Featured Articles PRO slider themes allow you to set up any kind of HTML structure. Depending on each theme specific display, the structure may be slightly different but there is a basic structure that should be followed.
Below you will find a simple slider structure but please note that you can implement it in a different way. This example consists of a slider container and inside it are the slides and navigation. This structure is actually taken from theme Simple, available in both PRO and Lite versions of the plugin.

<div class="<?php the_slider_class( 'my-slider-theme' );?>" style="<?php the_slider_styles();?>" id="<?php the_slider_id();?>" <?php the_slider_data();?>>
	<?php 
		// loop slides in slider
		while( have_slides() ): 
	?>
	<div class="fa_slide <?php the_fa_class();?>" style="<?php the_slide_styles();?>">		
		<div class="fa_slide_content">	
			<?php 
				// display the slide title wrapped in h2 tag
				the_fa_title('<h2>', '</h2>');
			?>
			<?php 
				// display the slide content wrapped in div
				the_fa_content('<div class="description">', '</div>');
			?>
			<?php 
				// display read more link
				the_fa_read_more('fa_read_more');
			?>
			<?php 
				// display play video link
				the_fa_play_video('fa_play_video', 'modal');
			?>
		</div><!-- .fa_slide_content -->
		
		<?php 
			// show the slide image wrapped in a div
			the_fa_image( '<div class="fa_image">', '</div>', false );
		?>			
	</div><!-- .fa_slide -->
	<?php 
		// end loop
		endwhile;
	?>
	<?php 
		// show sideways navigation if enabled
		if( has_sideways_nav() ):
	?>
		<div class="go-forward"></div>
		<div class="go-back"></div>
	<?php endif;?>
	<?php 
		// show dots navigation if enabled
		if( has_bottom_nav() ):
	?>
		<div class="main-nav">
			<?php while( have_slides() ):?>
			<a href="#" title="" class="fa-nav"></a>
			<?php endwhile;?>		
		</div>
	<?php endif;?>
</div>

As you probably have noticed, there are several templating functions implemented by the plugin that you can use into slider themes. These functions will do a lot of work in your place, almost like regular WP functions do in themes.

The most notable is the slides loop that will iterate all slides selected by the user and display them according to your design:

while( have_slides() ):
	// show slide stuff inside
endwhile;
