Gutenberg is a flexible and simple–to–use web typography starter kit for web designers and developers. It’s a small step towards a better typography on the web. Beautiful typographic styles can be made by setting base type size, line-height (leading) and measure (max-width).
Gutenberg sets the baseline grid to establish a proper vertical rhythm and makes sure all elements fit into it. It sets up the macro typography so you can focus on the micro–typographic details.
All calculations in Gutenberg depend on base type size and line-height. Multiplication of these two results in leading which is essential for setting a correct vertical rhythm and a baseline grid.
Gutenberg is built with Sass and works great with tools like Grunt or Gulp.
