Background will not go transparent on slideshow

I created a homepage for a client a while ago, and a recent update or change to her site has broken the original custom-css, and the content is no longer overlaid on the rotating gallery as it was.

The design is a full screen rotating slideshow (3 images), that is overlaid with the client's logo, some text, a button and social media icons (linked). 

I have tried to debug and can see that the content is still there (somewhere), however for some reason it is not showing correctly. You can see super faintly in the image attached, the content that should be overlaying the slideshow with a transparent overlay.

This is the code that was previously working:

<style>
#header, #mobile.bar, #footer {
display: none !important;}
#page .page-section{
height:100vh!important}
#page .page-section:nth-child(2){
margin-top:-100vh!important;}
#page .page-section:nth-child(2) ,
#page .page-section:nth-child(2) .section-background {
background-color:transparent!important}
header, #footer-sections {
display:none!important}
</style>

This is the link to the page on the site: https://www.fionabasile.com/landing-page-1

Any help would be greatly appreciated 🙂 

Thank you so much, this worked! 🙂
