CSS transform: translateY(0) vs bottom: 0 - 详细解析与区别

transform: translateY(0) is a CSS transform property used to move an element vertically. translateY(0) means no movement in the vertical direction, keeping the element at its original position. \n\nbottom: 0 is a CSS positioning property used to set the offset of an element's bottom relative to the bottom of its containing block (parent element). bottom: 0 means aligning the element's bottom with the bottom of its containing block, effectively fixing it to the bottom position. \n\nTherefore, transform: translateY(0) only affects the visual presentation of an element, not its position in the document flow. On the other hand, bottom: 0 changes an element's position in the document flow, fixing it to the bottom.
