How to creat Post Summaries before showing complete Post?
Expandable Post Summaries is the method by which each blog post consists of a short paragraph of introduction followed by a 'Read More' link. This enables the reader to get a small introduction to each post on the main page. He can then click the Read More link if he gets sufficiently interested…….. Many bloggers have reported confusion when they tried to follow the instructions on the official blogger help page for this hence I have tried to put the help in more easy to follow terms here. There are basically three steps to follow if you want to implement expandable post summaries in the new layouts template.
The first step is to put the code for the conditional css. This changes how posts display on different pages. To do this login to Dashboard and click on Layout for your blog. Then click on Edit HTML and first backup your template by using the Download Full Template link. Then scroll down till you come to </head> tag and add the following code immediately above it :
<style> <b:if cond='data:blog.pageType == "item"'>

span.fullpost {display:inline;}


span.fullpost {display:none;}


Save Template.
IMPORTANT NOTE in the layouts template there is a ]]></b:skin> tag just above the </head> tag. Add the above code so that it lies between these two tags. What we did here was to define a class called "fullpost" that will appear only on post pages (permalinks).
The second step is to add the Read More links which will appear after the paragraph summaries. To do this put a check in the Expand Widgets Template checkbox at the top of the Edit Template text box. This is in the Edit Html subtab of Template tab. Then scroll down in the code till you come to the Blog Posts Widget code where locate this line of code :


Add the code below immediately after the above code :

<b:if cond='data:blog.pageType != "item"'><br />

<a expr:href='data:post.url'>Read more!</a>


Save Template. This link will only appear on the main page and archive pages, and it will redirect your reader to the post page containing the full text of your post.
The last step is to modify the post template so that each post when created will show you where to place your summary paragraph and where to place the rest of the post. To do this go to Settings——>Formatting and scroll down to the end of the page to the box for the Post Template. Copy and Paste the following lines there :
Here is the beginning of my post. <span class="fullpost">And here is the rest of it.</span>
Save Settings. When you click on Create Post and then Edit Html tab of Post Editor you will see the following:

Replace the line "Here is the beginning of my post." (Type your summary here) with your summary paragraph. Then replace the line "And here is the rest of it." (Type rest of the post here.) with the rest of your post. Do not delete the other lines <span class="fullpost"> and </span>. Also add your summary paragraph above both the lines and your rest of the post between the lines. Then click Publish to publish post.
