validation error please help

hi
I have a problem with Revolution Slider

//echo '<div class="revsliderstyles">';
			echo '<style>';

			$db = new UniteDBRev();

			$styles = $db->fetch(GlobalsRevSlider::$table_css);
			foreach($styles as $key => $style){
				$handle = str_replace('.tp-caption', '', $style['handle']);
				if(!isset($this->class_include[$handle])) unset($styles[$key]);
			}

			$styles = UniteCssParserRev::parseDbArrayToCss($styles, "\n");
			$styles = UniteCssParserRev::compress_css($styles);
			echo $styles;

			echo '</style>'."\n";
			//echo '</div>';

when I validate the site it couse error

becouse <style> is not allowed when i change it, it is ok but there is no effect on the site or shows the css code

I try lots of things but it doesn’t work

How can i change it ? could anyone help me?

Element style not allowed as child of element div in this context. after validation
