حجم DOM

لماذا يهم

Every element costs memory, style calculation and layout time. Pages with thousands of elements respond slowly to taps and clicks (Interaction to Next Paint) and render slowly on phones.

كيفية الإصلاح

1. Remove hidden duplicate markup, such as separate mobile and desktop menus.
2. Paginate or lazy-render long lists, comments and product grids.
3. Flatten deeply nested wrapper elements produced by page builders.
