The CSS Cascade Layers property allows you to define a stack of layers that apply to CSS rules. This enables more fine-grained control over how styles are applied and overridden. Layers can be useful for managing large stylesheets and ensuring that certain styles always have precedence over others. It provides a way to organize CSS in a more modular and maintainable manner.
The sandbox attribute for iframes allows you to impose restrictions on the content within an iframe. This attribute enhances security by disabling certain features like form submission, script execution, and plugins within the iframe. It’s useful for isolating untrusted content and preventing potential security vulnerabilities.
