Layers in Third-Party Code
Wrap third-party CSS libraries in layers to safely control their cascade priority.
The Third-Party CSS Problem
Third-party CSS frameworks (Bootstrap, Tailwind, Bulma) often use high specificity selectors or !important that conflict with your own styles. Wrapping them in layers solves this without modifying the framework source.
Assigning Third-Party to a Low-Priority Layer
Assign imported third-party CSS to an early (low-priority) layer:
@layer vendor, components, utilities;
@import url('https://cdn.jsdelivr.net/npm/bootstrap/dist/css/bootstrap.css')
layer(vendor);All lessons in this course
