REASON 1

Open a sample directly in a browser to see one web performance technique in action.

REASON 2

Learn why a website feels slow by studying a hands-on example of a common performance problem.

REASON 3

Use a specific sample as a reference when discussing performance tradeoffs with engineers.

REASON 4

Pick up a new optimization technique quickly without reading lengthy documentation.

Wtf does this do

This repository is a collection of small code examples and samples designed to teach web performance optimization, the practice of making websites load faster and run more smoothly. Think of it as a learning toolkit: rather than dense documentation, it provides concrete, hands-on examples you can study and experiment with. The repository contains HTML files and related code snippets that demonstrate specific performance concepts. Each sample typically focuses on one technique or problem, things like reducing file sizes, speeding up how quickly a page becomes interactive, or making animations run without stuttering. By looking at working examples, you can see exactly how to apply these ideas in real projects. Who would find this useful? Anyone building websites who wants to understand performance fundamentals without drowning in theory. A founder launching a web app might use these samples to understand why their site feels slow. A PM working with engineers needs concrete examples to discuss performance trade-offs. A self-taught developer learning to build websites can see best practices in action. Even experienced developers sometimes benefit from quick reference examples when picking up a new optimization technique. The repository is written in straightforward HTML and code, making it accessible to people at any skill level. Rather than requiring you to run complex build tools or frameworks, you can often open these examples directly in a browser and see the concepts in action. The collection appears to be organized as a learning resource, so it likely grows over time as more examples are added to cover different performance topics.
