About This Skill
What it does
This skill provides a foundational understanding of frontend development principles. It enables AI agents to grasp core concepts like HTML structure, CSS styling, and basic JavaScript interactivity – allowing them to assist with tasks ranging from simple webpage creation to debugging existing code. The agent can explain these concepts in plain language or generate snippets of code based on user requests.
When to use it

- Debugging minor code issues: The agent can assist in identifying syntax errors or styling inconsistencies in existing frontend code.
- Learning about accessibility best practices: You need guidance on how to make a website more accessible for users with disabilities.
