Salut astazi am sa va arat cum puteti instala cel mai bun slider JQuery Nivo Slider :

Primul pas trebuie sa hostati acest cod Jquery

, dupa ce ati hostat acest cod va trebui sa il introduceti in afisare-templeturi-general-overall_header si il veti introduce inainte de tagul

Cod:: </head>

/

Acuma va trebui sa introduceti codurile html de preferat in index_box , insa le puteti introduce si in alte templeturi

Cod:: <div id="slider"> <img src="http://i22.servimg.com/u/f22/16/22/84/13/nemo11.jpg" alt="" /> <a href="http://dev7studios.com"><img src="http://i22.servimg.com/u/f22/16/22/84/13/toysto11.jpg" alt="" title="#htmlcaption" /></a> <img src="http://i22.servimg.com/u/f22/16/22/84/13/up10.jpg" alt="" title="This is an example of a caption" /> <img src="http://i22.servimg.com/u/f22/16/22/84/13/walle10.jpg" alt="" /> </div> <div id="htmlcaption" class="nivo-html-caption"> <strong>This</strong> is an example of a <em>HTML</em> caption with <a href="#">a link</a>. </div>

dupa ce ati introdus codul html introduceti urmatorul cod Jquery dupa ele

Cod:: <script type="text/javascript"> $(window).load(function() { $('#slider').nivoSlider(); }); </script>

si nu in ultimul rand css

Cod:: #slider { position:relative; width:618px; height:246px; margin-left:190px; background:url(http://i22.servimg.com/u/f22/15/42/72/40/loadin10.gif) no-repeat 50% 50%; } #slider img { position:absolute; top:0px; left:0px; display:none; } #slider a { border:0; display:block; } .nivo-controlNav { position:absolute; left:260px; bottom:-42px; } .nivo-controlNav a { display:block; width:22px; height:22px; background:url(http://i22.servimg.com/u/f22/15/42/72/40/bullet10.png) no-repeat; text-indent:-9999px; border:0; margin-right:3px; float:left; } .nivo-controlNav a.active { background-position:0 -22px; } .nivo-directionNav a { display:block; width:30px; height:30px; background:url(http://i22.servimg.com/u/f22/15/42/72/40/arrows10.png) no-repeat; text-indent:-9999px; border:0; } a.nivo-nextNav { background-position:-30px 0; right:15px; } a.nivo-prevNav { left:15px; } .nivo-caption { text-shadow:none; font-family: Helvetica, Arial, sans-serif; } .nivo-caption a { color:#efe9d1; text-decoration:underline; } /* The Nivo Slider styles */ .nivoSlider { position:relative; } .nivoSlider img { position:absolute; top:0px; left:0px; } /* If an image is wrapped in a link */ .nivoSlider a.nivo-imageLink { position:absolute; top:0px; left:0px; width:100%; height:100%; border:0; padding:0; margin:0; z-index:6; display:none; } /* The slices and boxes in the Slider */ .nivo-slice { display:block; position:absolute; z-index:5; height:100%; } .nivo-box { display:block; position:absolute; z-index:5; } /* Caption styles */ .nivo-caption { position:absolute; left:0px; bottom:0px; background:#000; color:#fff; opacity:0.8; /* Overridden by captionOpacity setting */ width:100%; z-index:8; } .nivo-caption p { padding:5px; margin:0; } .nivo-caption a { display:inline !important; } .nivo-html-caption { display:none; } /* Direction nav styles (e.g. Next & Prev) */ .nivo-directionNav a { position:absolute; top:45%; z-index:9; cursor:pointer; } .nivo-prevNav { left:0px; } .nivo-nextNav { right:0px; } /* Control nav styles (e.g. 1,2,3...) */ .nivo-controlNav a { position:relative; z-index:9; cursor:pointer; } .nivo-controlNav a.active { font-weight:bold; }

Nota:Daca sliderul nu va merge introduceti primul cod jquery in acelasi loc cu codurile html !
