Custom text for both titles and captons on fullwidth sliders – desktop and mobil

Hello
I’ve looked at lots of posts and tried everything but I could only get the mobile to work. Here’s my mobile code (break point is max 989).

	/* MOBILE - WORKS */
	
	/* sliders - titles and captions *************************************/

	.caption_bottom .slideshow_caption .slideshow_inner_caption {
	    margin-bottom: 20px; /* tight for images on white as well */
	}
	/* adjust vertical position of caption */

	.av_slideshow_full .container.caption_container {
		margin: 0px 0px 0px 20px !important;	
	}
	
	/* slider titles - default is h2 but using h3 styling */

	.avia_transform .av_slideshow_full .avia-caption-title {
		/* font-family: 'Roboto', sans-serif; */
		font-family: 'Noto Sans JP', sans-serif;
		font-style: normal;
		font-weight: 400;	
		font-size: 16px;
		line-height: 20px;
		letter-spacing: 1px;
		color: #575757 !important;
		text-transform: uppercase;		
		text-shadow: 0px 0px 0px #000 !important;
		margin: 0px 0px 5px 0px !important;		
	}

	/* slider descriptions - h4 */
	
	.caption_bottom .slideshow_caption .avia-caption-content p {
		/* font-family: 'Roboto', sans-serif; */
		font-family: 'Noto Sans JP', sans-serif;
		font-style: normal;
		font-weight: 500;	
		font-size: 14px;
		line-height: 18px;
		letter-spacing: 1px;
		color: $575757 !important;
		text-transform: uppercase;		
		text-shadow: none !important;
		margin: 0px 0px 0px 0px !important;			
	}
	
	/* applied class of topSliderMobileWhite to the fw slider */
	
	.responsive #top .topSliderMobileWhite .slideshow_caption h2 {
		color: #999 !important;
	}

	.responsive #top .topSliderMobileWhite .slideshow_caption .avia-caption-content,
	.responsive #top .topSliderMobileWhite .slideshow_caption .avia-caption-content p {
		color: #999 !important;
	}

For desktop, I applied a class of topSliderWhite to the fw slider, but it’s not picking up the changes. Here’s the code I tried.

This test is on the Solutions page –

/* DESKTOP - NOT WORING */

/* all titles unless overridden below - same styling as h1 but with shadow */

.avia_transform .av_slideshow_full .avia-caption-title {
	/* font-family: 'Roboto', sans-serif; */
	font-family: 'Noto Sans JP', sans-serif;
	font-style: normal;
	font-weight: 400;	
	font-size: 24px;
	line-height: 28px;
	letter-spacing: 1px;
	color: #fff;
	text-transform: uppercase;		
	text-shadow: 2px 2px 4px #000;
	margin: 0px 0px 0px 0px !important;		
}

/* on white version - apply .topSliderWhite to fs slider - not working */

.topSliderWhite .avia-caption-title {
	color: #ff0066 !important;	
	text-shadow: none !important;			
}

/* all descriptions unless overridden below - same as h2 */

.avia-caption-content p {
	/* font-family: 'Roboto', sans-serif; */
	font-family: 'Noto Sans JP', sans-serif;
	font-style: normal;
	font-weight: 400;	
	font-size: 18px;
	line-height: 24px;
	letter-spacing: 1px;
	color: #fff;
	text-transform: uppercase;	
	/* background: black; */	
	text-shadow: 2px 2px 4px #000;
	margin: 10px 0px 0px 0px !important;			
}

/* on white version - apply .topSliderWhite to fs slider - can't get any of these to work properly */

.topSliderWhite .avia-caption-content,
.topSliderWhite .avia-caption-content p {
	color: #ff0000 !important;	
	text-shadow: none !important;
}

.caption_bottom .slideshow_caption .topSliderWhite .avia-caption-content,
.caption_bottom .slideshow_caption .topSliderWhite .avia-caption-content p {
			
}

/* this changes the background but not the text */

.topSliderWhite .avia-caption-content,
.topSliderWhite .avia-caption-content p  {
	margin-bottom: -80px; /* tweak to offset height of controls and make v spacing for page h1 the same */
	text-align: left;
	background: orange !important;
	color: green !important;
}

.avia_transform .av_slideshow_full .active-slide .topSliderWhite .avia-caption-content,
.avia_transform .av_fullscreen .active-slide .topSliderWhite .avia-caption-content {

}

Am I missing something really obvious? Thank you!
