Related post widget with thumbnail

CSS code

Please use the CSS code below so that the related posts are not lined up to the side but down. And if you want to modify the appearance to match the blog theme, please modify this CSS.

.related-bottomposts,.related-post h4 {display:none}
.related-post{margin:5% 5% 0;padding:0;font-family:'Open Sans',sans-serif;text-align:left;width:100%;position:relative;color:#000}
.related-post a{font-weight:600;color:#000;font-size:16px!important;}
.related-post a:hover{color:red}
.related-post-style-3,.related-post-style-3 li{margin:0!important;padding:0!important;list-style:none;word-wrap:break-word;overflow:hidden}
.related-post-style-3 .related-post-item{display:block;width:90%;max-width:300px;height:auto;padding:150px 0 10px;margin-bottom:20px!important}
.related-post-style-3 .related-post-item-thumbnail{display:block;margin:0 0 5px;width:99%;height:140px;max-width:none;max-height:none;background-color:transparent;padding:0;transition:all 400ms ease-in-out;border:1px solid #ddd}
.related-post-style-3 .related-post-item-thumbnail:hover{opacity:.7}
.related-post-style-3 .related-post-item:focus,.related-post-style-3 .related-post-item:active{outline:0}

HTML code

Now copy the code given below.

<b:if cond='data:blog.pageType == "item"'>
<div class='related-bottomposts'>
<div class='related-post' id='related-post'/>
</div>
<script type='text/javascript'>
var labelArray=[<b:if cond='data:post.labels'><b:loop values='data:post.labels' var='label'>
"<data:label.name/>"<b:if cond='data:label.isLast != "true"'>,</b:if>
</b:loop></b:if>];var relatedPostConfig={widgetStyle:3,callBack:function(){if(window.addEventListener){window.addEventListener("DOMContentLoaded",insertRelatedPostMarkupToSidebar,false);window.addEventListener("load",insertRelatedPostMarkupToSidebar,false)}else{if(window.attachEvent){window.attachEvent("onload",insertRelatedPostMarkupToSidebar)}else{window.onload=insertRelatedPostMarkupToSidebar}}}};
</script>
</b:if>

And paste the code (above) just below the following code or something similar to this.

<b:if cond='data:blog.pageType == "item"'>
<data:post.body/>
</b:if>
<b:if cond='data:blog.pageType == "static_page"'>
<data:post.body/>
</b:if>
<div class='clear'/> 
</div>

Javascript code

Now copy the code given below and paste it just above </body> tag of your template.

<b:if cond='data:blog.pageType == "item"'>
<script type='text/javascript'>
//<![CDATA[

//]]>
</script>
</b:if>

Please Note:- You have to replace the URL http://factsbyteinjournal.blogspot.com/ with your blog URL and also specify the number of related posts you want to display in the following code numPosts:7

Determining the Target Gadget Sidebar

So, now look carefully at this step, because each blog sometimes has a different sidebar tag, so don't stick to the sidebar tag in this code, but adjust it to the template you are using.

You have to specify a place to display the related posts, for example, If you want to display the sidebar under popular posts, widget and for example the sidebar code with popular posts as below.

So, you have to save the code given below just below the code </b:widget>

<b:widget id='HTML5' locked='false' title='Related Posts' type='HTML'>
<b:includable id='main'>

<b:if cond='data:title != ""'>
<h2 class='title'><data:title/></h2>
</b:if>
<div class='widget-content' id='related'>
<data:content/>
</div>
</b:includable>
</b:widget>

So it becomes something like this like this:

<div id='sidebar-wrapper'>
<b:section class='sidebar3' id='sidebar3' preferred='yes'>
<b:widget id='PopularPosts1' locked='false' title='Popular Posts' type='PopularPosts'>
<b:includable id='main'>
...............
...............
...............
</b:includable>
</b:widget>
<b:widget id='HTML5' locked='false' title='Related Posts' type='HTML'>
<b:includable id='main'>

<b:if cond='data:title != ""'>
<h2 class='title'><data:title/></h2>
</b:if>
<div class='widget-content' id='related'>
<data:content/>
</div>
</b:includable>
</b:widget>
</b:section>
</div>

Now SAVE your template. If it turns out that the template cannot be saved because there is a double id from HTML5(pay attention to this code id='HTML5'in the Related Posts gadget), you have to replace the number 5 with whatever it takes to prevent double id, for example to id='HTML30'. The key is the code id='related' as a target for placing HTML related posts by javascript.

And if you want to change the gadget title, don't change it through the layout because it will get an error. But change it from javascript given above.

Related post widget without thumbnail

You have to do all things the same as describing have but you have to replace CSS and javascript code with these ones.

CSS Code

.related-bottomposts{display:none}.related-post h4 {Font-size:25px;color:#000;}
.related-post h2{text-align:center;font-size:30px;color:#000;}
