CSS Style 4
Bước 3: Tìm đến thẻ hiển thị nội dung bài viết /* Related Post in Post */
.post-terkait {position:relative;background:#fff;padding:0;margin:10px 15px 0 0;float:left;width:165px;border:1px solid #1b71bc}
.post-terkait h4{background:#1b71bc !important;padding:5px 0 !important;margin:0;text-align:center !important;font-size:15px !important;font-weight:400;text-transform:uppercase;color:#fff !important}
.post-terkait ul {margin:0;padding:0}
.post-terkait ul li {list-style:none !important;padding:7px 0;margin:0 7px;border-bottom:2px dotted #ddd;line-height:1.4em !important;text-align:left !important}
.post-terkait ul li:last-child{border:none !important}
.post-terkait a {color:#1b71bc;font-size:13px !important}
.post-terkait a:hover {text-decoration:underline}
<data:post.body/>
và thay thẻ này bằng đoạn code sau<div expr:id='"post1" + data:post.id'/>
<div class='related-simplify'>
<b:if cond='data:post.labels'>
<b:loop values='data:post.labels' var='label'>
<b:if cond='data:blog.pageType == "item"'>
<script expr:src='"/feeds/posts/default/-/" + data:label.name + "?alt=json-in-script&callback=related_results_labels&max-results=3"' type='text/javascript'/>
</b:if>
</b:loop>
</b:if>
<h4>Bài viết cùng chuyên mục</h4>
<script type='text/javascript'>
removeRelatedDuplicates();
printRelatedLabels();
</script>
</div>
<div expr:id='"post2" + data:post.id'><p><data:post.body/></p></div>
<script type='text/javascript'>
var obj0=document.getElementById("post1<data:post.id/>");
var obj1=document.getElementById("post2<data:post.id/>");
var s=obj1.innerHTML;
var t=s.substr(0,s.length/2);
var r=t.lastIndexOf("<br>");
if(r>0) {obj0.innerHTML=s.substr(0,r);obj1.innerHTML=s.substr(r+4);}
</script>
Cuối cùng Lưu Mẫu lại và xem kết quả nhé !
