how to replicate pinterest.com’s absolute div stacking layout [closed]

I wrote the Pinterest script. The ID’s are unrelated to the layout, and are used for other interaction-related JS. Here’s the base of how it works:

Beforehand:

  • Absolutely position the pin containers
  • Determine column width
  • Determine margin between columns (the gutter)

Setup an array:

  • Get the width of the parent container; calculate the # of columns that will fit
  • Create an empty array, with a length equaling the # of columns. Use this array to store the height of each column as you build the layout, e.g. the height of column 1 is stored as array[0]

Loop through each pin:

  • Put each pin in the shortest column at the moment it is added
  • “left:” === the column # (index array) times the column width + margin
  • “top:” === The value in the array (height) for the shortest column at that time
  • Finally, add the height of the pin to the column height (array value)

The result is lightweight. In Chrome, laying out a full page of 50+ pins takes <10ms.
