# Slide Columns

## Mechanisms

-   Header 3 markers (`###`)
-   Box classes (`.split` and `.join`)
-   Slide masters (`layout` slide attribute)

# Header 3 Markers

------

# Header 3 Markers

## Syntax

-   Each H3 mark (`###`) starts a new column
-   Columns are generated as DIVs

### 

## Semantics

-   The slide header is not part of the columns
-   Columns vertically span the entire slide
-   Space is equally distributed between all columns

------

# Box Classes

------

# Box Classes

## Intro

-   No columns here, just a very long line spanning the entire slide

## Syntax {.split}

-   Box headers (`##`) are marked with CSS classes
    -   `split` starts 2 columns
    -   `join` forces 1 column

## Semantics

-   CSS3 column attributes are used for breaking
-   Breaks occur on box borders

## Outro {.join}

-   No columns here, just a very long line spanning the entire slide

------

# Box Classes

-   No columns here
-   But possibly very long lines, longer than any column is wide

## Syntax {.split}

-   Box headers (H2) are marked with CSS classes
    -   `split` starts 2 columns
    -   `join` forces 1 column

-   Assign content to layout area
-   On elements *Header 2*, *Image*, *Code Block*, *DIV*

------

# Slide Masters {layout="top2columns"}

## Fixed Layouts {.top}

This is probably all bullshit anyway

-   Columns are generated as DIVs

## Semantics

-   The slide header is not part of the columns
-   Columns vertically span the entire slide
