Selectors
summary
History-driven account claims CSS selects only nodes of an element-tree model and shows which selectors actually solve real problems: attribute selectors for URLs and alt flags, the sibling selector (~) to style paragraphs after an H1, pseudo-classes like :target and :not and the limits that make :not error-prone, and structural selectors including the nth-child formula (2n+4, odd/even). Live demos test each pattern and Level 4 proposals target missing use cases rather than restating topics.
