Bước 1: Thêm đoạn css sau vào trước thẻ ]]></b:skin> hoặc thẻ </style>

/* Related Post CSS */ .related-post-item-tooltip{height:54px;overflow:hidden;width:50%;float:left;text-overflow:ellipsis;padding:10px}#related-post .material-icons{font-size:200%;right:20px;color:#607D8B;top:-1px;position:absolute}#related-post{background:#fff;margin:10px}.related-post{margin:30px 0 0;position:relative;padding:0 0 10px}.lol h4 i,.related-post h4 i{margin-right:14px}.lol h4,.related-post h4{border-radius:4px;color:#555;font-size:100%;font-family:'Roboto',Arial;text-transform:uppercase;text-align:left;font-weight:700;box-shadow:0 2px 5px 0 rgba(0,0,0,0.16),0 2px 10px 0 rgba(0,0,0,0.12);position:relative;padding:15px 20px 12px;margin:0 0 20px}.related-post-style-3,.related-post-style-3 li{margin:0 auto;padding:0!important;list-style:none;word-wrap:break-word}.related-post-style-3 li a{font-family:'Roboto',sans-serif;color:#666;font-weight:700!important;font-size:14px;line-height:1.4em}.related-post-style-3 li a:hover{color:#111}.related-post-style-3 .related-post-item{display:inline-block;float:left;border-radius:3px;box-shadow:0 2px 5px 0 rgba(0,0,0,0.16),0 2px 10px 0 rgba(0,0,0,0.12);width:47%;margin-right:15px;height:auto;padding:0;margin-bottom:20px!important;position:relative;overflow:hidden}.related-post-style-3 .related-post-item:focus{outline:none;border:none}.related-post-style-3 .related-post-item-thumbnail{display:block;margin:0;width:40%;height:100px;float:left}.related-post-style-3 .related-post-item-thumbnail img{width:100%;height:auto!important;transition:all 1s ease-out}.related-post-item:hover .related-post-item-tooltip a{opacity:1}.related-post-item-tooltip a{color:#666!important;transition:transform .6s cubic-bezier(.175,.885,.32,1.275),opacity .3s;text-align:center;font-size:12px!important;position:relative} @media screen and (max-width:480px){.related-post-style-3 .related-post-item{width:100%!important}.related-post-style-3 .related-post-item-thumbnail{height:100px!important}}

Bước 2: Dán đoạn code sau vào nơi bạn muốn bài viết liên quan xuất hiện.
