block vs inline - mmedrano9438/peripheral-brain GitHub Wiki

• "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-level 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)."

• "In an inline formatting context, boxes are laid out horizontally, one after the other, beginning at the top of a containing block. Horizontal margins, borders, and padding are respected between these boxes. The boxes may be aligned vertically in different ways: their bottoms or tops may be aligned, or the baselines of text within them may be aligned. The rectangular area that contains the boxes that form a line is called a line box."

Block elements in a horizontal writing mode such as English, lay out vertically, one below the other.

In a vertical writing mode then would lay out horizontally.
