This course teaches HTML entities as character references, not as a button-by-button walkthrough of an encoder tool. You will learn why HTML needs escaping, how named and numeric entities differ, where CMS and template workflows introduce double-encoding bugs, and how to debug mixed entity strings in logs and exports.

Who this course is for

  • Frontend developers preparing safe HTML, JSX, or template output
  • CMS editors and content engineers cleaning exported fields
  • Backend developers reading escaped log lines or API payloads

What you will learn

  1. What an HTML entity represents and when browsers decode it
  2. Named entities such as & versus decimal & and hex &
  3. Escaping rules for text nodes, attributes, and CMS exports
  4. Common mistakes such as double encoding or treating decode as sanitization
  5. A practical workflow for batch logs and mixed-format strings

Use the related HTML Entity Encoder to experiment, but remember: decoding reveals characters—it does not make untrusted HTML safe to render.
