en détail le > en fin de :
... href="/modules/slider/css/nivo-slider.css" rel="stylesheet" type="text/css" />
et le > en fin de
<style type="text/css">

Le problème que je rencontre est que je n'arrive pas à comprendre ce que je doit changer dans la source de la page tpl qui génére ce code


contenu du tpl :

{if $slides|@count != 0}
<script type="text/javascript" src="{$this_path}js/jquery.nivo.slider.pack.js"></script>
<link href="{$this_path}css/nivo-slider.css" rel="stylesheet" type="text/css" />
<style type="text/css">

        width:{$xml->width}px;
        height:{$xml->height}px;
    }
    .nivoSlider{
        width:{$xml->width}px;
        height:{$xml->height}px;
    }
    .nivo-prevNav {
        width:{math equation="x / y" x=$nav.0 y=2}px;
        height:{math equation="x / y" x=$nav.1 y=2}px;
    }
    .nivo-nextNav {
        width:{math equation="x / y" x=$nav.0 y=2}px;
        height:{math equation="x / y" x=$nav.1 y=2}px;
    }

        top:{$xml->dirnavpos}%;
    }

        {$xml->ctrlnavhorizpos}: 0;
        top: {$xml->ctrlnavpos}%;
    }
    .nivo-controlNav a {
        width: {$bullets.0}px;
        height: {math equation="x / y" x=$bullets.1 y=2}px;
    }
</style>
    
<div id="slide_holder"> 	
    <div id="slider">
            {foreach from=$slides item=slide}
                {if $slide.active==1}
