Overview

Sanitizes HTML content by removing empty elements and cleaning up inline styles.
Used primarily for blog posts and article content rendered from WYSIWYG editors.

Cleans up common issues:

  • Empty and list elements that create unwanted whitespace
  • Inline styles that conflict with CSS layout (clear, margins, padding, float)
  • Unnecessary tags inside table cells
  • Adds Bootstrap table classes (table w-auto) so tables fit beside floated sidebar
