Content, arguments and parameters

By default, folium includes some utilities to get your content laid out quickly. These are largely inspired by the way Flutter handles declarative UI.

By content, we mean any of the following:

• centre takes one single argument of type content and places it in the centre of its bounding box;
• padding takes one single argument of type content and adds some padding to it. The amount can be controlled via the amount parameter;
• row and column take at least one argument of type content and lay them out in a row or in a column;
• text takes one argument of type string and displays the text; size can be controlled by the size parameter (a number representing the size in points), the fill colour can be controlled by the fill parameter which is a string with a hex colour code in it)

Practical presenting

A folium presentation is built up of a sequence of slides.
A slide is delimited with square brackets ([, ]) and contains a central block of content and optionally extra styling directives.

The first expression in a slide should be some content to display. By default, a slide renders its content at full width and full height.

A slide looks roughly like this:

[
    // main content
    < element >

    // styling directives for the slide itself
    slide {
        key: value
    }

    // styling directives for named elements 
    element_name {
        key: value
    }
]

The slide also has some parameters, namely width, height and bg.
