With this trick, you can choose to display an arbitrary amount of text from the beginning of each post, as a teaser for the whole thing. Then users who want to read the rest of the post can click a "Read More..." link to see the full text. This is handy if you have lots of long articles all on one page. Note that you don't need to change any code in TypoXP Blooger in order to make this feature work.

Each post that you want to use this feature on will need this code:

<span class="fullpost"></span>

You'll enter the summary text outside the span tags and the remainder inside, like so:

Here is the beginning of my post.
<span class="fullpost">And here is the rest of it.</span>

Now, when a reader visits your blog, this post will appear like this:

Here is the beginning of my post.
Read more...

When they click the link, they'll go to the post page where they'll see the whole thing:

Here is the beginning of my post.
And here is the rest of it.
