Bước 2:
Tìm tiếp đoạn code sau : "<div class='comments' id='comments'>
sau đó thêm vào
<b:if cond='data:blog.pageType == "item"'> <div id='related-posts'> <b:loop values='data:post.labels' var='label'> <b:if cond='data:label.isLast != "true"'> </b:if> <b:if cond='data:blog.pageType == "item"'> <script expr:src='"/feeds/posts/default/-/" + data:label.name + "?alt=json-in-script&callback=related_results_labels_thumbs&max-results=6"' type='text/javascript'/></b:if></b:loop> <script type='text/javascript'> var currentposturl="<data:post.url/>"; var maxresults=6; var relatedpoststitle="<b>Related Posts:</b>"; removeRelatedDuplicates_thumbs(); printRelatedLabels_thumbs(); </script> </div></b:if>
