   {% if post.content.size > 2000 %}
      {{ post.content | truncatewords: 300 }} <!-- bad! content gives you rendered html and you will truncate in the middle of a node -->

<!--break-->

Paragraph 3

Paragraph 4

Great!

Cool, thanks

This Gist was super helpful, thanks! But as I was implementing your solution, I realized truncation may still be used viably using this method:

{{ post.content | strip_html | truncatewords: 300 }}

But this is assuming you're okay with removing paragraph structure and such and want to spit out plain-text.

Just what I needed. Thanks!

Useful, thanks!

Thanks! Very useful!

Great, Thanks !

Amazing! Thanks!

very nice 👍

Good. then, you can do this:

---
excerpt_separator: <!--more-->

---

Excerpt
<!--more-->
Out-of-excerpt

// Need remove the <p> tags.
{{ post.excerpt | remove: '<p>' | remove: '</p>' }}

{{ post.content | strip_html | truncatewords: 140 }}

Thanks for this post! I'm just in trouble like this.

Awesome!

Just what I needed, thank you!
