Cool – almost there.
Edit the Header Element – in the Element Classes field add: slider
Then add this CSS:
.page-hero.slider {
position: relative;
}
.page-hero.slider h1 {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
display: flex;
justify-content: center;
align-items: center;
z-index: 1;
background-color: rgba(0,0,0,0.25); /* Overlay color */
}
.page-hero.slider .metaslider {
padding-bottom: 0;
}
Note this line is optional:
background-color: rgba(0,0,0,0.25); /* Overlay color */
This adds a background overlay to cover the slider.
