CSS is critical to rendering a page—a browser will not begin rendering until all CSS has been found, downloaded, and parsed—so it is imperative that we get it onto a user’s device as fast as we possibly can. download any CSS needed for the current context (medium, screen size, resolution, orientation, etc.) Avoid @import in CSS Files.

For these, it’s important to turn off auto-completing forms, encrypt data both in transit and at rest with up-to-date encryption techniques, and disable caching on data collection forms. To avoid these problems, set up automated DevSecOps release validation and security gates so that no insecure code progresses to production.

We are explicit about our dependencies, so we know what code we need to run to run a specific component. Lazy-loading and bundle splitting can have a huge impact on page performance: less code requested, parsed, and executed. When you send the user code that is not needed, you waste resources from your end, and from the user’s end.
