推薦答案
這是一個 CSS 子選擇器.<代碼>P >SPAN 意味著將遵循的樣式應用于作為 P 標記的子級的所有 SPAN 標記.
It's a CSS child selector. P > SPAN means applying the style that follows to all SPAN tags that are children of a P tag.
請注意，孩子"的意思是直接后代"，而不僅僅是任何后代.P SPAN 是一個后代選擇器，將遵循的樣式應用于作為 P 子級的所有 SPAN 標簽標記或作為 P 標記的子/后代的任何其他標記的遞歸子代.<代碼>P >SPAN 僅適用于 SPAN 標記，它們是 P 標記的子標記.
Note that "child" means "immediate descendant", not just any descendant. P SPAN is a descendant selector, applying the style that follows to all SPAN tags that are children of a P tag or recursively children of any other tag that is a child/descendant of a P tag. P > SPAN only applies to SPAN tags that are children of a P tag.
