Hey, 

Password for my website - BS

I'm looking to add text onto the full screen homepage gallery slideshow you first see when you go onto my website. I basically want to add the phrase 'Scroll down for more' at the bottom of the gallery over the image so people can see it on all of the images. I've attached a screen shot below showing where I'd want the text. 

If anyone could help I'd really appreciate it, Thanks!

Can you send the link of the site?

Hey,  it's www.bethsquire.com

Add the below code in the page header code injection of the page 

.gallery-fullscreen-slideshow::after {
    content : "Scroll down for for more";
    position : absolute;
    bottom : 20px;
    left : 50%;
    z-index: 9;
    translate: -50% 0;
    font-size : 16px;
    color : #fff;
}
