How Can I Hover Image On Top Of Another?

Question

This might be really easy for many people but I just can't do it as I am not a developer. I am trying to hover image on top of another. It works but when I hover I can still see the another image at the background. When I hover the two images (same size) overlay each other and give different color.

Here is the CSS code:

.votebutton {
    text-align:center;
    background: transparent;
    width: 24px;
    height: 25px;
    overflow: hidden;
    float: right;
    margin: -21px -28px 0px 0px;
}
.votebutton a: {
}
.votebutton a:hover {
    background-image: url(../img/thumbs.png);
    position:relative;
    display: inline;
    z-index: 2;
    top: 2;
    height: 5px;
    width: 10px;
}

HTML

<div id="vote" class="votebutton">{if $anonymous_vote eq "false" and $user_logged_in eq ""} 

   <a data-toggle="modal" href="#LoginModal" class="btn btn-mini {if $link_shakebox_currentuser_votes eq 1}btn-success{/if}">

{else} {if $link_shakebox_currentuser_votes eq 0}

Edit: Have updated the full code. Thanks.

Im not exactly sure what you are trying to achieve. If it is simply a hover affect for you link then using :hover should work as you are attempting.

Here is a fiddle that does a basic background hover change - http://jsfiddle.net/f6Frt/1

You simply set a background image for you link, then change that on hover.

.votebutton a {
    padding: 20px;
    background-image: url('http://twimgs.com/informationweek/galleries/automated/818/Slide-1-opening-image-38launch_full.jpg');
    background-size: 100%;
}

.votebutton a:hover {
    color:rgba(0,0,0,0);
    background-image: url('http://spaceinimages.esa.int/var/esa/storage/images/esa_multimedia/images/2004/01/reull_vallis_-_hrsc_image_15_january_20042/9758050-3-eng-GB/Reull_Vallis_-_HRSC_image_15_January_2004_node_full_image.jpg');
    background-size: 100%;
}

If you only want to show a background image on hover then omit the background from the css, as shown here http://jsfiddle.net/f6Frt/2

If you want to make the link text invisible then you can set its color to transparent:

.votebutton a:hover{color:rgba(0,0,0,0);}

shown here - http://jsfiddle.net/f6Frt/3/

If you want to take it a step further, you could use jQuery to clear the html content on hover, shown here - http://jsfiddle.net/f6Frt/4/ - this will require some extra tweaking, but is a good start if you're new to jQuery.

Hope this helps.
