Base typographic styles for Scales CSS
These are the base styles for typographic elements.
Scales uses the Sass CSS preprocessor, you'll need either Ruby Sass or LibSass.
* NPM: npm install --save @scales/base-typography
Scales provides default typography for headings, text elements, lede paragraphs, and code blocks. It also has utility classes for headings and to control measure and truncation.

Measure is the length of a line of text. For maximum readability, this should optimally be set between 45 and 75 characters. With multiple columns of text the measure should be narrower, between 40 and 50 characters.

This allows you to cut text off if it exceeds the width of the viewport and adds an ellipsis. This works even better when combined with utilities-size to control where it cuts off by applying a width to the container.

#### The Scales Namespace Variable
All Scales patterns expose the
variable.$scales-namespace accepts a string that will prefix all Scales classes. The default value is null.#### Class Level Namespace Variable
Class level namespace variables allow you to namespace a selector based on the type e.g.
b- for "base", o- for "objects", u- for utilities, and c- for "components".This pattern exposes the
$scales-base-class-namespace variable.$scales-base-class-namespace accepts a string that will prefix any classes in this pattern and follow the Scales Namespace Variable if it is not null. The default value is null.#### Namespace Variable Usage
To set either of these namespaces, you will need to set the variables in a file that is imported before any scales files. For example:
`
@import your-project/settings; // Namespace variables are set in this file
@import your-project/scalescss; // Imports all of the Scales packages
@import your-project/project // The rest of your project imports
