Home page excerpts gives your audience a brief view about a bunch of your posts at once and if they are interested in any of them, they’ll click on that post link to read the full entry.
Note that excerpts will only show when visitors view the home page or archived page. Now to do this you have to enable post pages first (Go to settings–>archiving and enable post pages).
You need to add three bits of code here to get through the process. I’m assuming that you have the latest template type blog and not the classic template blog.
Go to layout and click on edit HTML.
Add the following code in your template style sheet. That is in between the <style> </style> tags. If you do not find the style tags just add it below the opening <head> tag.
<b:if cond=’data:blog.pageType == “item”‘>
Then search for <data:post.body/> tag.(Use ctrl+f to make your search easy).
Add the following code after that <data:post.body/> tag.
<b:if cond=’data:blog.pageType != “item”‘><br />
<a expr:href=’data:post.url’>Read the rest of the entry</a>
The changes in your template are done. Now you have to add a small bit of code to every post that you want to show as a excerpt.
Add <span class=”fullpost”></span> to every post in HTML mode.
You need to add it to every post should you want every post to show only an excerpt in your Home page and archive page. There is no cut out for this.
Anyway, this is Blogger and not WordPress right?
