## LaTeX Environments

::: {.center}
The contents of this div will be output in a `center`
LaTeX environment, but will appear in HTML (and any other output 
format as a simple div with the class `center`)
:::

## LaTeX Commands

Will replace spans of class `ce` with the `\ce{}` command for LaTeX output, but leave the spans intact for HTML output. So `[H2SO4]{.ce}` becomes [H2SO4]{.ce}.

## Advanced Environments and Commands

You can also combine environments and commands (with options) to address more complex scenarios. Usually with LaTeX: 
* `[opts]` is used for optional arguments
* `{args}` for mandatory arguments

Both environments and commands can accept an `options` and `arguments` attributes which will be properly applied in LaTeX and will be available as an attribute in HTML output.

:::{.enumerate}
[]{.item options="--"} Question 1
[]{.item options="--"} Question 2

[This text is in a orange background]{.colorbox arguments="BurntOrange"}

If you have multiple arguments or options to pass to a command, use comma separated string

[This one will have a black border]{.fcolorbox arguments="black,red"}
