I recently set up my blog and on the home screen, the full blog posts are shown. Is there a way to cut off the blog posts at some point in the text? As it is now, my home screen is extremely long with a bunch of full blog posts.
That is usually dependent upon the theme that you are using. But you can also manually set each blog post to only show so much with the
<!-- more --> tag that you insert in to each post.
If you're wanting to update the theme template file, you'd replace the_content() function call with the_excerpt() function call (see the Codex for details on how to use) in the template file that is being loaded on your home page which depends upon the theme. Could be front-page.php or archive.php or index.php in your selected theme's directory.
This is usually done by including a
<!--more--> tag in your post. You can insert this tag by clicking on the "Insert More Tag" toolbar button as you are editing your post. The toolbar button looks like this:
The portion of your blog post above that tag will be shown on your home screen. The portion below that tag will be hidden unless the user clicks through using the "Continue Reading" link.
