## Showcasing
### Style with Markdown

==Markdown== is all you need! Elements like $tex$ and `code` are rendered with elegant style.

!!! note
    moffee automatically breaks pages and chooses titles based on context.

### Media Layout

One of moffee's strengths is using dividers to organize text and images effectively.

===

- Use `---` to trigger page breaks.
- Use `<->` to arrange elements horizontally.
- Use `===` to split elements vertically.

moffee automatically adjusts element sizes to accommodate large blocks of text or complex illustrations.

Or you can use other built-in themes:

default	beam	robo
blue	gaia

Installation

moffee is written in Python and is recommended to install with pipx. See our documentation for step-by-step instructions.

pipx install moffee
# or `pip install moffee`

Preview slides in a live web server or export to HTML:

moffee live example.md # launch a server
# or
moffee make example.md -o output_html/ # export to HTML

Usage

To start, write in standard markdown. moffee supports most extended syntax found in Obsidian Flavored Markdown. See the syntax documentation for more details.

# Markdown Title
Use **bold** and *italic* for emphasis.

- Extended syntax like ~~strikethroughs~~ is supported.

To create a new slide, begin a new heading:

## Page 1
Some text

## Page 2
This sentence will appear on the second slide.

Alternatively, use --- to manually trigger a new slide:

## Page 1
Text on the first slide
---
Text on the next slide.

You'll notice the second slide shares the Page 1 title. moffee selects the most suitable title for each slide.

In addition to ---, moffee supports <-> and === for in-slide layout. Use <-> to separate elements horizontally:

Text on the left.
<->
![Image on the right](https://placehold.co/600x400)

=== places elements vertically and takes precedence over <->. Use them together for flexible layouts:

Top bun
===
Patty on the left
<->
Lettuce on the right
===
Bottom bun

Options and Styles

Front matter is used to define moffee's behavior. Here are some common used options. Refer to Configuration for the full list.

---
theme: default # Other availble themes are "beam", "robo", "blue" and "gaia"
layout: content # HTML template. Use "centered" for centered alignment.
resource_dir: "." # Relative URLs are based on this directory.
aspect_ratio: "16:9" # Aspect ratio of the slides
---

Any CSS property can be set in the front matter. For example, set a dark gray background for all slides:

---
layout: content
background-color: darkgray
color: white
---

moffee also supports local style decorators with the syntax @(property=value). Use these within the document to set attributes for specific slides:

# A refined landing page
Our journey begins here
@(layout=content, background-image='url("https://placehold.co/600x400")')
