## What it is
An open-source educational book explaining the differences between commonly confused concepts in front-end development, covering CSS, DOM, HTML, and JavaScript. It is written in MDX and includes good practices, tips, and 'Good to know' sections.

- look up subtle web development distinctions

## When to choose
- you want concise explanations of confusing front-end concept pairs
- you are learning CSS, HTML, DOM, or JavaScript fundamentals
- you want free, practical web development tips and good practices

## When to avoid
- you need a runnable tool or library rather than reading material
