O melhor gadget de artigos relacionados para colocar no Blogger

Este é um dos melhores gadgets de artigos relacionados, existente atualmente na web! Eu utilizava este gadget nas páginas deste website, mas, resolvi retirá-lo por motivos pessoais! Se você teve a sorte de achá-lo, e desejar adicionar no seu blog ou website, fique a vontade para fazer isso. Mas, será necessário ter algum conhecimento sobre os códigos do Blogger, CSS, HTML e JavaScript! Recomendo que você leia também esse outro artigo - possui outro modelo de gadget, e ensina como colocar artigos relacionados com imagens no Blogger.

O CSS deverá ser adicionado acima de  "]]></b:skin>":

#related-posts{clear:both;margin-top:20px;margin-bottom:0;width:590px !important;}
#related-posts h3{font-family: 'Pathway Gothic One', sans-serif;font-size:18px;font-weight:400;text-shadow: 0 0 1px rgba(0,0,0,0.5);-webkit-font-smoothing: antialiased;text-transform:none;line-height:20px;padding-top:20px;display:none !important;}
#related-posts ul li a,#related-posts li a .title h4{color:#fff;font-size:12px;padding:0;margin:0;outline:0;list-style:none;outline: none;border:0 none}
#related-posts ul{margin-bottom:20px;padding:10px 0;}
#related-posts ul li{list-style:none;overflow:hidden;float:left;margin:0 5px 5px 0;height:200px;width:290px;font-size:13px;color:#fff;position:relative;}
#related-posts ul li:last-child{margin:0 0 10px 0;}
#related-posts li .thumb{width:290px;height:200px;overflow:hidden;}
#related-posts img{width: 290px;height: 210px;min-height:210px;float:left;margin:0;padding:0 !important;}#related-posts img:hover{opacity:.8}
#related-posts li .thumb img{height:200px;width:290px;}
#related-posts li{background:transparent !important;}
#related-posts li .title{position:absolute;bottom:0;left:0;background:#383832 !important;width:100%;padding:10px 5px;}
#related-posts li a :hover{text-decoration:none !important;color:#fff !important;background:#4c86f0 !important;}

Este código javascript deverá ser adiconado acima de "</head>":

Esta outra parte do código deverá ser adiconada acima de "<div class='post-footer'>" (alguns templates do Blogger, têm duas linhas "<div class='post-footer'>", nesse caso, adicione o código acima da segunda linha):

 <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>
<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=999&quot;' type='text/javascript'/>
</b:loop>
<script type='text/javascript'>
var currentposturl=&quot;<data:post.url/>&quot;;
var maxresults=4;
var relatedpoststitle=&quot;Artigos Relacionados&quot;;
removeRelatedDuplicates_thumbs();
printRelatedLabels_thumbs();
</script></div></b:if><div style='clear:both'/>

Agora, basta salvar o template e visualizar a página do blog; os artigos relacionados irão aparecer no final dos artigos, somente nas páginas internas do blog.
