Header images on this site I'm building are appearing too dark - I can't see any opacity is being applied - http://www.stayinblackpool.co.uk/ - any ideas what could be causing this?
Tried to make opacity 1.0
Opacity is being applied - in the form of background alpha key. Here is your markup:
<div class="featured-image">
<img src="http://www.stayinblackpool.co.uk/wp-content/uploads/2019/02/header3.jpg">
<div class="overlay">
<div class="grid-mid">
<h1 class="page-title">Serviced Holiday Apartments in North Shore, Blackpool</h1>
</div>
</div>
</div>
and here's associated CSS:
.overlay {
background: rgba(0,0,0,0.5);
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
}
If you notice background has rgba, 0.5 is causing 50% opacity. I would remove the background attribute completely.
