Rollover Hover Image on HTML Button

Question

So I am currently building a landing page for an app that will be soon coming online - However, I have only developed the iOS version so far and will start the android development once the iOS version has gone live.

Now, on my landing page - I have 2 buttons that will redirect to either the Apple store or Google play. For the apple store everything is fine, however I want to add a text that appears when going over the Google Play button which will say something like "coming soon!".

I have tried something but since I am not an expert when it comes to web development, the outcome below clearly shows that swell.. Can anyone help?

If I understood your question. You want a the coming soon text to come up whenever anyone hover the playstore button. Please use the code below as reference.

Note : The .container div here is just for example. You should put the code inside .container in your li and make required changes with img src and other styles

.container{
  width: 50%;
  padding: 50px;
  background: #444;
  text-align: center;
}
.my-btn-class{
  position: relative;
  display: block;
}

.my-btn-class img{
max-width: 100%;
}

.my-btn-class:hover > .btn-over{
  display: flex;
}

.btn-over{
  position: absolute;
  width: 100%;
  height: 100%;
  background: rgba(0,0,0,0.8);
  display: none;
  top: 0px;
  align-items: center;
  justify-content: center;
  color:#ddd;
  font-weight: 600;
}

<div class="container"><!--Example div. Use the below code in your li -->
<a class="my-btn-class" href="#" data-store="android" target="_blank">
      <picture class="picture picture--no-background" style="padding-bottom: 34.88%"><img src="http://via.placeholder.com/350x150" alt="Download the Android app"></picture>
      <div class="btn-over">
      Coming Soon
      </div>
</a>
</div>

Hope this helps
