In a block formatting context, boxes are laid out one after the other, vertically, beginning at the top of a containing block. The vertical distance between two sibling boxes is determined by the 'margin' properties. Vertical margins between adjacent block boxes in a block formatting context collapse.
In a block formatting context, each box's left outer edge touches the left edge of the containing block (for right-to-left formatting, right edges touch). This is true even in the presence of floats (although a box's content area may shrink due to the floats).
在块格式化上下文中，框从包含块的顶部开始一个接一个地垂直排列。两个兄弟框之间的垂直距离由“边距”属性决定。块格式上下文中相邻块框之间的垂直边距折叠。
在块格式上下文中，每个框的左外边缘接触包含块的左边缘（对于从右到左的格式，右边缘接触）。即使存在浮动也是如此（尽管盒子的内容区域可能会因浮动而缩小）。
