I think this should be relatively easy to do but I just can't get it to work. I have my btn centered nicely over my image using display flex. I want the btn to appear when the user hovers over the image, and when they move the cursor off the image it disappears. I'm also wanting to add a subtle ease-in-out effect so it transitions smoothly. Any help is much appreciated. Here is my css and html.
HTML
<div class="row">
<div class="col-md-4">
<div class="imgAbout">
<img src="http://placehold.it/580x410" class="img-responsive" alt="Neil Elmouchi Bio">
<div class="center-container">
<a class="btn btn-sm btn-primary" href="bios/teamBioNeil.html">View More</a>
</div>
</div>
<h1>Name</h1>
<h3>Chairman & CEO<br>
Senior Wealth Advisor</h3>
</div> <!-- end col-md-4 -->
</div>
CSS
#about img {
margin: 0 auto;
}
.imgAbout {
position: relative;
}
.imgAbout img {
display: block;
height: auto;
}
.center-container {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
display: flex;
align-items: center;
justify-content: center;
}
