Este código está adaptado para o novo Blogger, 2013

Para ter um template com uma estrutura de layout melhor sou adepta dessa maneira de apresentar a página inicial do blog. Fica harmonioso, organizado, facilita a navegação para o leitor e ainda economiza espaço no template. Depois de mais uma mudança no Blogger, a maneira de implementar este hack deu uma modificada, mas é possível, com um pouquinho mais de ateção implementa-la perfeitamente.


Vá até o modelo de seu blog, clique em "Editar HTML"

Procure por <b:skin>...</b:skin> que está logo acima no código.

Abaixo dele, cole o código abaixo

<style>
/*Botão leia mais-----------------------------------------------------------*/
#showlink{
float: right;
background: #C0C0C0;
margin: 6px 3px 8px 0;
padding:4px 3px;
-moz-border-radius:8px;
-webkit-border-radius:8px;
-moz-box-shadow: 0px 10px 10px -7px #888;
-webkit-box-shadow:0px 10px 10px -7px #888;
}
#showlink a:hover{
background: #fff;
padding:4px 3px;
font-size: 16px;
}

#showlink a {
color: #000;
}
</style>

Agora  novamente, depois de


<b:skin>...</b:skin>

Copie um dos códigos dos modelos abaixo e cole depois dele.

Salve.

Agora procure pelo seguinte trecho:

<b:if cond='data:blog.metaDescription == &quot;&quot;'>
      <!-- Then use the post body as the schema.org description,
          for good G+/FB snippeting. -->
      <div class='post-body entry-content' expr:id='&quot;post-body-&quot; + data:post.id' itemprop='description articleBody'>
        <data:post.body/>
        <div style='clear: both;'/> <!-- clear for photos floats -->
      </div>
    <b:else/>
      <div class='post-body entry-content' expr:id='&quot;post-body-&quot; + data:post.id' itemprop='articleBody'>
        <data:post.body/>
        <div style='clear: both;'/> <!-- clear for photos floats -->
      </div>
    </b:if>




Troque-o então por:

<b:if cond='data:blog.metaDescription == &quot;&quot;'>
      <!-- Then use the post body as the schema.org description,
          for good G+/FB snippeting. -->
      <div class='post-body entry-content'>
<b:if cond='data:blog.pageType != &quot;item&quot;'>
<b:if cond='data:blog.pageType != &quot;static_page&quot;'>
<div expr:id='&quot;summary&quot; + data:post.id'><data:post.body/></div>
<script type='text/javascript'>createSummaryAndThumb(&quot;summary<data:post.id/>&quot;);</script>
<span id='showlink'><a expr:href='data:post.url'>Leia Mais &#9658;</a></span>
</b:if></b:if>
<b:if cond='data:blog.pageType == &quot;item&quot;'>
<data:post.body/></b:if>
<b:if cond='data:blog.pageType == &quot;static_page&quot;'><data:post.body/>
</b:if>
<div style='clear: both;'/> <!-- clear for photos floats -->
      </div>
    <b:else/>
      <div class='post-body entry-content' expr:id='&quot;post-body-&quot; + data:post.id' itemprop='articleBody'>
        <data:post.body/>
        <div style='clear: both;'/> <!-- clear for photos floats -->
      </div>
    </b:if>

Salve e está pronto
