  css layout positioning float

  • “You should always set a width on floated items (except if applied directly to an image – which has implicit width). If no width is set, the results can be unpredictable.”
  • “For one, the box being floated should have a width defined for it, either explicitly or implicitly. Otherwise, it will fill its containing block horizontally, just like non-floated content, leaving no room for other content to flow around it. Second, unlike boxes in the normal flow, the vertical margins of a floated box are not collapsed with the margins of boxes either above or below it. Finally, a floated box can overlap block-level boxes adjacent to it in the normal flow.”

  CSS Web-Development WebDesign Web Positioning Layout

  • A floated box is positioned within the normal flow, then taken  out of the flow and shifted to the left or right as far as possible.
  • “When you float an element it becomes a block box. This box can  then be shifted to the left or right on the current line.
  • “You should always set a width on floated items
  • The first thing we need to remember is that a floating element is shifted either  to the left or to the right. It is not possible to make an element float in the  centre
  • When we float an element it is shifted to the right or to the left until it  reaches the edge of the containing block. If we then float another element  nearby in the same direction, it will be shifted until its edge reaches the edge  of the first floating element
  • “Since a float is not in the flow, non-positioned block boxes created before and  after the float box flow vertically as if the float didn’t exist
  • An inline box is generated by those elements that aren’t block-level
  • A line box is an imaginary rectangle that contains all the inline boxes that  make up a line in the containing block-level element
  • If we then want a full-width footer to be shown at the bottom, no matter which  column happens to be longest, we only need to set clear: both on  it.”
  • rely on browsers to consistently interpret the layout

  • The term “float” refers to the way in which an element floats to one side and down
  • A floated box is positioned within the normal flow, then taken out of the flow and shifted to the left or right as far as possible. Content may flow along the side of a float. [...] When a box is taken out of normal flow, all content that is still within normal flow will ignore it completely and not make space for it.
  • When you float an element it becomes a block box.
  • You should always set a width on floated items (except if applied directly to an image - which has implicit width). If no width is set, the results can be unpredictable.
  • Since a float is not in the flow, non-positioned block boxes created before and after the float box flow vertically as if the float didn’t exist
  • An inline box is generated by those elements that aren’t block-level, such as EM. [...] A line box is an imaginary rectangle that contains all the inline boxes that make up a line in the containing block-level element.
  • Elements following a floated element will wrap around the floated element. If you do not want this to occur, you can apply the “clear” property to these following elements.
  • The standard method of making an outer container appear to “enclose” a nested float is to place a complete “cleared” element last in the container, which has the effect of ‘dragging’ the lower edge of the containing box lower than the float
