Overview of nested cascade layers.
To understand cascade layers, you must understand the CSS cascade well.
Within each of the six origin buckets, there can be multiple cascade layers. The order of layer creation matters a lot.
If you understood most of this article, then well done- you're now familiar with the fundamental mechanics of CSS cascade layers.
To learn how cascade layers work.
The@layer CSS at-rule is used to declare a cascade layer and to define the order of precedence when there are multiple cascade layers.
Issues nested cascade layers can solve.
Cascade layers enable the prioritizing of entire stylesheets over other stylesheets, without having to worry about specificity between these sub-origins.
Let's first discuss what cascade layers are and what issues they solve.
Cascade layers are most relevant when you're working with CSS from multiple sources, when there are conflicting CSS selectors and competing specificities, or when you're considering using!

This lesson aims to introduce you to cascade layers, a more advanced feature that builds on the fundamental concepts of the CSS cascade and CSS specificity.
Similar to how we have six levels of priority based on origin and importance, cascade layers enable us to create sub-origin level of priority within any of those origins.
The more you work with CSS, understanding cascade layers and knowing how to leverage their power will save you from a lot of pain managing a code base with CSS from different parties, plugins, and development teams.
In the same way that cascade origins provides a balance of power between user, user-agents, and author styles, cascade layers provide a structured way to organize and balance concerns within a single origin, as if each layer in an origin were a sub-origin.
The ability to nest layers enables teams to create cascade layers without worrying about whether other teams will import them into a layer. .
Each cascade layer can contain nested layers. .
Cascade layer precedence order.
Each cascade layer, even an anonymous one, can contain nested layers. .
We now understand“cascade origin precedence”, but what is“cascade layer precedence”?
A regular cascade layer will add the component library to the author origin, removing any specificity conflicts with other author styles. Within the components layer, a developer can choose to define various themes, each as a separate nested layer. .
