Elementor own admission: Flexbox Containers ship 40% less HTML output than sections/columns

Claim: Elementor's own engineering blog admits: "Containers produce 40% less HTML output than sections and columns for the same layout."

Source: Elementor engineering blog (2023-2024).

Confidence: Verified (vendor admission).

Why this is the punchiest data point: Elementor itself documents that the default markup in pre-Container Elementor was bloated by 40%+. Sites built before Flexbox Containers (introduced 2022) are still on the old section/column system unless they've been migrated. The vendor has acknowledged the cost; the customer has paid it.

The deeper architectural problem: Even with Flexbox Containers, page builders generate deeply nested <div> structures (5-7 layers around a single paragraph is typical — per Seismic Pixels and Anubiz analyses). Container adoption helps but doesn't eliminate the structural issue. See Anubiz Host: Elementor adds 500KB+ of CSS/JS to every page; simple pages can have 2000+ DOM elements.
