I was working on a my friend site, when I needed to use a slideshow, so I decided to use: WP Orbit Slider, it’s a nice wordpress plugin but it hasn’t a good description visualization, so I edited a bit the default css to have this result:

First I inserted a slideshow into Twenty Eleven homepage (I had already created slides)   editing index.php, where I write this code before /* Start the Loop */ comment

<?php 
echo do_shortcode('[orbit-slider]') 
?>

Then I edited WP Orbit plugin‘s default.css, I added this rule

.slide-content {
top: 230px !important;
left: 200px !important;
padding: 2%;
background: black;
opacity: 0.7;
filter: alpha(opacity=70);
height: 30px !important;
text-align: center;
width: 180px !important;
color: white;
}

and I edited “#orbit-inside a” in this way:

#orbit-inside a {
	display:block;
	width:100%;

        color:white !important;
        text-decoration: underline !important;
}

The end!
