Check out this example I've put together for you. Feel free to customize it to suit your specific requirements.
If you'd like to see a live demonstration, here's a link to the fiddle: http://jsfiddle.net/829mL4z1/1/
Here's the HTML code snippet:
<div class="holder">
<img alt="your-alt" src="http://doc.jsfiddle.net/_downloads/jsfiddle-logo.png"/>
<div class="info">
My text<br/>
<input type="button" value="Button"/>
</div>
</div>
For the jQuery implementation:
$(document).ready(function(){
$('.holder').on('mouseenter',function(){
$(this).find('.info').fadeIn();
});
$('.holder').on('mouseleave',function(){
$('.info').fadeOut();
});
});
And here's the corresponding CSS styling:
.holder{
position: relative;
border: 1px solid #000000;
width: 100px;
}
.info{
position: absolute;
display: none;
background: rgba(255,255,255,0.8);
color: #000000;
text-align: center;
bottom: 0;
z-index: 100;
width: 100%;
}
img{
width: 100px;
}
