Hi there,
1. edit the Header Element and on the Site Header tab change the Merge with Content to No Merge
.
This will stop the content from sliding behind the navigation.
2. Slightly tricker go the Page Hero tab :
a. In the Element Classes field add: hero-has-overlay
b. Add this HTML below the Slider Shortcode:
<div class="hero-overlay">
<!-- put your text content in here -->
</div>
c. Save the Header Element and add this CSS to your site:
.hero-has-overlay {
position: relative;
}
.hero-overlay {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
display: flex;
justify-content: center;
align-items: center;
background-color: rgba(0,0,0,0.5);
}
