@knighttower/bootstrap-mini

Bootstrap Mini

Built on top of Bootstrap but modified to have only the basic utilities classes and the grid system. This is a (very) lightweight CSS version that can be used to build websites and web applications.
It is not meant to replace the full functionality of Bootstrap, only to abstract the basic utilities to use in quick prototypes, small projects or to compliment other frameworks since it does not add any root styles, resets or normalize, colors or other theme styles that would override or conflict. It can also be customized with a few variables before importing the file to load only a few utilities or the full set.
Out the box it can be used from the cdn but to further reduce the size, it can be installed as a node module and imported as a sass file to be compiled with postcss.

Usage (stand-alone):

npm install @knighttower/bootstrap-mini -D

@import '~@knighttower/bootstrap-mini/dist/bootstrap-mini.css';

Or to use the sass file, and use the sass functions and utilities:

@import '~@knighttower/bootstrap-mini/src/bootstrap-mini.scss';

Usage (monorepo):

npm install knighttower

@import '~knighttower/bootstrap-mini/src/bootstrap-mini.scss';

or as a drop-in css file into vite or webpack ``` import "@knighttower/bootstrap-mini/dist/bootstrap-mini.css" ```

If using the sass file, some variables are available to be modified before importing the file. These are the defaults

$miniPrefix: bs-;
$miniColumns: 12;
$miniGutterWidth: 1.5rem;
$miniRowColumns: 6;
$miniFontSizeBase: 1rem;

$miniEnableMargins: true;
$miniEnablePadding: true;
$miniEnableWidth: true;
$miniEnableHeight: true;
$miniEnableZIndex: true;

$miniEnableFloat: true;
$miniEnablePosition: true;
$miniEnableDisplay: true;
$miniEnableVisibility: true;
$miniEnableContainer: true;
$miniEnableGridClasses: true;
$miniEnableCssGrid: true;

Then do:

$miniEnableMargins: false;  
//... other overrides before the import  
@import '~@knighttower/bootstrap-mini/src/bootstrap-mini';

Gotchas

• when using the @import in a sass file, make sure to use the tilde (~) to point to the node_modules folder and add resolvers to the 'node_modules' folder in the sass-loader configuration in webpack or vite.

Why?

Most CSS frameworks come loaded with themes, or bulky in general that makes it hard the quick use without getting the full package or having to modified them to get only what you need. I also (IMO) think that the grid system bootstrap offers, has simple and versitile enough to be used in quick projects. (I'll discuss that in a future post).
Please notice, that there are things that are not included in this tyny version, the intention of this it to be basic, and if more functionality is needed, or theme styles need to be applied, then you should go full framework with Bootstrap [https://getbootstrap.com], Tachyons [https://tachyons.io], unoCSS [https://unocss.dev] (I have my eye on this one), etc...

PS: as of the writting of this, I have been implementing the minibootstrap (only the grid and cssgrid) along with UnoCss and this is a killer combo. (notice that UnoCss does not provide a strong grid but bootstrap does). I'll talk about this more at https://knighttower.io

Credits to the Bootstrap team for the great work they have done.
