Beginner-Level Terms
“The foundation you can’t skip.”
- WordPress
The world’s most-used content management system (CMS), perfect for building websites without coding. It comes in two flavors: WordPress.com (hosted) and WordPress.org (self-hosted). Open-source, customizable, and beginner-friendly. - Dashboard

- Widget
Functional blocks (like a search bar or recent posts) are placed in sidebars, footers, or widget-ready areas. - Block Editor (Gutenberg)
The drag-and-drop editing system uses “blocks” for paragraphs, images, lists, embeds, etc. Replaces the Classic Editor. - Short code
Bracketed code snippets like[form id=1] embeds advanced functionality into pages or posts.
