# Context:
USER: github-pages 228 | Error: Liquid syntax error (line 1): Unknown tag 'extends'
ASSISTANT: It seems like you are using Jekyll with GitHub Pages, and the error is related to the Liquid template engine not recognizing the `{% extends %}` tag. The `{% extends %}` tag is not a standard Liquid tag, but it is a part of the Jinja2 template engine.
To fix this issue, you need to modify the `_layouts/chat-transcript.html` file to use Liquid's standard tags and remove the `{% extends %}` tag. You can use the `default.html` layout as a base and include the `chat-transcript.html` specific changes.
Here's the updated `_layouts/chat-transcript.html` file:
```html
_layouts/chat-transcript.html
<<<<<<< ORIGINAL
{% extends "default.html" %}
{% block styleoverride %}
<style>
blockquote {
background-color: yellow;
}
</style>

>>>>>>> UPDATED
```
This update removes the `{% extends %}` and `{% block %}` tags and includes the specific changes for `chat-transcript.html` directly in the file.
# Context:
USER: i would like to add a new <style> block to the <head> of chat-transcript, which sets the background color of blockquotes to yellow
ASSISTANT: To add a new `<style>` block to the `<head>` of `chat-transcript.html`, you can use the `{% block %}` tag to override the existing `<head>` section in the `default.html` layout. Here's how to do it:
```html
_layouts/chat-transcript.html
^C KeyboardInterrupt
USER: i don't want to replace the entire head. maybe add a styleoverride block to default (empty) and then use it in chat-transcript?
ASSISTANT: Sure, you can add an empty `styleoverride` block in `default.html` and then override it in `chat-transcript.html`. Here's how to do it:
1. Add an empty `styleoverride` block in `default.html` inside the `<head>` section.
2. Override the `styleoverride` block in `chat-transcript.html` to add the new `<style>` block.
Here are the changes:
```html
_layouts/default.html
<<<<<<< ORIGINAL
<link rel="stylesheet" href="{{ '/assets/css/style.css?v=' | append: site.github.build_revision | relative_url }}">
{% include head-custom.html %}
=======
<link rel="stylesheet" href="{{ '/assets/css/style.css?v=' | append: site.github.build_revision | relative_url }}">
{% include head-custom.html %}
{% block styleoverride %}{% endblock %}
>>>>>>> UPDATED
```
```html
_layouts/chat-transcript.html
<<<<<<< ORIGINAL
{% block content %}
=======
{% block styleoverride %}
<style>
blockquote {
background-color: yellow;
}
</style>
{% endblock %}
{% block content %}
>>>>>>> UPDATED
```
Now, the `chat-transcript.html` layout will have the new `<style>` block setting the background color of blockquotes to yellow, while the `default.html` layout remains unchanged.
# Context:
USER: make a new layout called chat-transcript.html which is identical to default. can we inherit from default somehow?
ASSISTANT: Yes, you can create a new layout called `chat-transcript.html` that inherits from `default.html` using the `{% extends %}` and `{% block %}` tags in Liquid. Here's how to do it:
1. Create a new file called `chat-transcript.html` in the `_layouts` directory.
2. In the new file, use the `{% extends "default.html" %}` tag to inherit from `default.html`.
3. Use the `{% block content %}` and `{% endblock %}` tags to define the content area that will be replaced in the child layout.
Here's the new `chat-transcript.html` layout file:
```html
_layouts/chat-transcript.html
<<<<<<< ORIGINAL
=======
{% extends "default.html" %}
{% block content %}
{{ content }}
{% endblock %}
>>>>>>> UPDATED
```
This new layout will inherit everything from `default.html` and replace the content area with the content of the pages that use the `chat-transcript` layout.
