If you are running the Fable theme for WordPress by Elegant Themes, then you may notice this little bug when you use features images. The text or post title of the WordPress post is usually hidden because it cannot be seen over the featured image.

To add the transparent overlay please add the following code to the Custom CSS box in the ePanel options:

.category .post.entry.et-background-image:before {
content:'';
display:block;
width:100%;
height:100%;
z-index:999;
position:absolute;
top:0;
background:rgba(0,0,0,0.5);
}
.category .post.entry .container.clearfix {
z-index: 9999999;
}
