what is front-end-checklist fr?

The Front-End Checklist is a comprehensive reference document for web developers to verify that a website is properly built before launching it to the public. The problem it solves is ensuring nothing important gets forgotten: when building a website there are dozens of technical details that are easy to overlook, like setting the correct character encoding, adding a favicon, configuring meta tags for search engines, ensuring accessibility for screen readers, and optimizing performance. This checklist compiles all of those requirements in one place. The repository is organized into sections covering the HTML document head (meta tags, favicons, canonical links), HTML structure, web fonts, CSS, JavaScript, and accessibility. Each item is labeled with one of three priority levels: high (must not be omitted or the page may break or fail SEO), medium (highly recommended but occasionally skippable), or low (best practice but can be omitted in certain contexts). The items are accompanied by explanations, links to relevant documentation, and links to online tools for testing each requirement. This makes it both a checklist to run through before launch and a learning resource for understanding why each item matters. You would use this repository as a pre-launch quality checklist when shipping a website, as onboarding material for new front-end developers on your team, or as a reference when reviewing someone else's code. It is particularly useful for developers who are building sites without a dedicated QA team. The repository itself is not software, it is documentation written in Markdown and HTML. There is no runtime or framework to install. The companion website and additional checklists (performance and design) are linked from the README.
