Posts Relacionados con miniaturas más grandes y efecto de opacidad

En esta oportunidad les voy a compartir un truco que estoy seguro les va a encantar y es otra forma de posts relacionados con imagenes en miniatura más grandes y efecto de opacidad al pasar el cursor sobre ellas.

Para agregar este truco a tu blog sigue los siguientes pasos:

1.  Agrega el siguiente script antes de  </head> 

<script type='text/javascript'>

//]]>
</script>

2.  Ahora agrega el siguiente CSS antes de  ]]></b:skin> 

#related-posts{float:left;width:105%;}
#related-posts h1{background:none;color:#173b3c;font:16px Oswald;padding:3px;text-shadow:0 1px 1px white}
#related-posts .maskolis_img {border:4px solid #999;padding:0px 0px;width:132px;height:165px;transition:all 400ms ease-in-out;-webkit-transition:all 400ms ease-in-out;-moz-transition:all 400ms ease-in-out;-o-transition:all 400ms ease-in-out;-ms-transition:all 400ms ease-in-out;margin:10px 8px 5px}
#related-posts .maskolis_img:hover{opacity:.8;filter:alpha(opacity=80);-moz-opacity:.7;-khtml-opacity:.7}

3.  Por ultimo pega el siguiente codigo debajo de <div class=’post-footer-line post-footer-line-3′>

<b:if cond='data:blog.pageType == &quot;item&quot;'>
<div id='related-posts'>
<b:loop values='data:post.labels' var='label'>
<b:if cond='data:label.isLast != &quot;true&quot;'>
</b:if>
<b:if cond='data:blog.pageType == &quot;item&quot;'>
<script expr:src='&quot;/feeds/posts/default/-/&quot; + data:label.name + &quot;?alt=json-in-script&amp;callback=related_results_labels_thumbs&amp;max-results=12&quot;' type='text/javascript'/></b:if></b:loop>
<script type='text/javascript'>
var currentposturl=&quot;<data:post.url/>&quot;;
var maxresults=6;
var relatedpoststitle=&quot;<b>Otros Post Interesantes</b>&quot;;
removeRelatedDuplicates_thumbs();
printRelatedLabels_thumbs();
</script>
</div><div class='clear'/>
</b:if>

El numero 6 resaltado en azul corresponde a las entradas que se van a mostrar.

Por ultimo guarda los cambios.
