Bootstrap Bits and Pieces is a serie of css/less/sass files adding new modular functionalities to Bootstrap.
It's my first public project, and it's not really "advanced" right now
The aim is to create fully modular bits and pieces you can add to your bootstrap css/sass/less to implement the functionalities you need
The first module is already released in a very early alpha stage it's called spaces and offer you the ability of implementing responsive vertical spacing based on the size of line-height-base, font-size-base, font-size-large and font-size-small
CSS:
just add the css files of the pieces you want after the bootstrap css
LESS:
@import the less files from the pieces you want after bootstrap variables.less
SASS:
@import the sass files from the pieces you want after bootstrap _variables.scss
