Question: I put this in the following file: index.html

```
<ul class="youtube">
    <li class="gamerscafe"><a href="https://www.youtube.com/channel/UClExmFafx9vTZxDHPwg74Pg"></a></li>
    <li class="destiny"><a href="https://www.youtube.com/channel/UCyrifIvvkvGj1c-ltnbop4A"></a></li>
    <li class="halo"><a href="https://www.youtube.com/channel/UCjdkHFov_Tqb9mzrEXStrog"></a></li>
    <li class="assassins"><a href="https://www.youtube.com/channel/UCSFscOh0tN1hsz-7UMIVYkQ"></a></li>
    <li class="gearsofwar"><a href="https://www.youtube.com/channel/UC26Tt6oTOS4UpdGzAOVMZKA"></a></li>
    <li class="armyoftwo"><a href="https://www.youtube.com/channel/UCqvhFvrTYsv3VGg9j9elNtA"></a></li>
</ul>

```

And i put this in the style.css sheet...

```
ul.youtube
{
width: 650px;
margin: 0px auto 0;
height: 10px;
}

ul.youtube li{
float: left;
background: url(../images/youtube.png) left top no-repeat;
position: relative;
height: 20px;
margin-right: 70px;
}

ul.youtube li a{
display: block;
width: 18px;
height: 20px;
}

```

However when i hover over the images the link doesn't work is there something i am missing ?

Answer: 
Like Felk said.

You have your `<a>` tag but it doesn't have anything inside.

In order to make the images links you would have to put them inside the `<a>` tag; like so.

```
<li class="gamerscafe"><a href="https://www.youtube.com/channel/UClExmFafx9vTZxDHPwg74Pg"><img src=""></img></a></li>
                                                                                                   //^ image code here

```
If you move your background image styling into the a tag it should work, like this:

```
ul.youtube li a{
    display: block;
    background: url(http://gamerscafe.net/images/youtube.png) left top no-repeat;
    width: 140px;
    height: 200px;
}

```

Then you can apply the positioning this way:

```
ul.youtube li.destiny a {
    background-position: -310px 0px;
}

```

And if you need hover effect:

```
ul.youtube li.destiny a:hover {
    /*style for hover*/
}

```

I have put your site into jsfiddle. Please take a look here for a working version:
