Avia Easy Slider Accessibility Change Recommendation

File: av-helper-slideshow.php

Could this code be updated to meet accessibility standards? Instead of using “<a href=’#prev’ ….” could you use “<button …”? The accessibility issue is that these links have no destination (necessary for WCAG 2.0AA). If a destination div with ids are added, and two slideshows are used on the same page, then there are duplicate “prev” and “next” id elements.

Code:

protected function slide_navigation_arrows()
		{
			global $avia_config;
		
			$html  = "";
			$html .= "<div class='avia-slideshow-arrows avia-slideshow-controls'>";
			$html .= 	"<a href='#prev'>".__('Previous','avia_framework' )."</a>";
			$html .= 	"<a href='#next'>".__('Next','avia_framework' )."</a>";
			$html .= "</div>";

			return $html;
		}

Thanks!
