How to create a summary of a post in WordPress?
WordPress gives you the options to create a summary (excerpt) of a post, as well as add a “More…” link to the post so that your visitors can click it and read the whole post.
To use these features for a new post, go to your blog’s admin area > Posts > Add New. To add the “More…” link to the post, click the Insert more tag button in the WYSIWYG editor menu above the message body.
If you prefer writing your posts in HTML mode, you can use the:
tag instead. It should be added after the text of your post.
In order to create a summary for your post, simply write it in the Excerpt field.
Click Publish to save and publish your new post.
