ITCSS: Structuring CSS from General to Specific
ITCSS organizes CSS from generic to specific, like an inverted triangle. It's for large projects to prevent specificity wars and make code predictable. The main footgun is not enforcing the layer order, which leads back to styling chaos and defeats the system.
ITCSS is a methodology that structures CSS files from broad, low-specificity rules (resets) to narrow, high-specificity overrides (utilities), forming an inverted triangle of influence. It excels in large apps and design systems by managing the cascade and avoiding conflicts. The common pitfall is adding rules to the wrong layer, like putting component styles in the generic 'Objects' layer, which breaks the specificity graph and reintroduces hard-to-debug styling issues.
