Chisel A WordPress Development Framework

ITCSS

ITCSS stands for Inverted Triangle CSS and it helps you make project CSS scalable and maintainable.

One of the key principles of ITCSS is that it separates your CSS codebase to several sections (called layers) which take form of the inverted triangle. These layers are present in Chisel as following folders inside the src/styles folder:

settings

Used with preprocessors and contain font, colors definitions, etc.

tools

Globally used mixins and functions. It’s important not to output any CSS in the first two layers.

generic

Reset and/or normalize styles, box-sizing definition, etc. This is the first layer which generates actual CSS.

elements

Styling for bare HTML elements (like H1, A, etc.). These come with default styling from the browser so you can redefine them here.

objects

class-based selectors which define undecorated design patterns, for example media object known from OOCSS

components

Specific UI components. This is where majority of your work takes place and our UI components are often composed of Objects and Components

utilities

Utilities and helper classes with ability to override anything which goes before in the triangle, eg. hide helper class

vendor

Chisel’s addition to the original ITCSS structure. This is where you can place vendor’s specific CSS.

main.scss

Main file where other stylesheets are imported, do not write styles directly to this file.

When starting to work with ITCSS in Chisel, try to follow existing code structure and examples.
