Replicating Pinterest's Absolute Div Stacking Layout

Pinterest's unique div layout presents a challenge to programmers seeking to replicate its functionality. The custom jQuery and CSS used to dynamically adjust the layout based on browser resize and prevent vertical stacking dependency leaves many wondering how to achieve similar results.

Answer:

The core principle behind Pinterest's layout involves absolutely positioning the pin containers, determining the column width and gutter size, and utilizing an array to track the height of each column.

1. Positioning Pin Containers:

Each pin container should be absolutely positioned within the parent container. This allows individual pins to be placed independently of each other.

2. Calculating Column and Gutter Sizes:

Determine the available width for pin containers and calculate the number of columns that fit comfortably. Use the resulting column width and a predefined gutter size to calculate the overall layout parameters.

3. Array-based Height Tracking:

Initialize an array with a length equal to the number of columns. As you iterate through each pin, determine which column has the shortest height at that moment. Store this height within the corresponding array element.

4. Pin Placement:

Iterate through each pin and:

• Position it within the column with the shortest height (determined by the array).
• Set the "left" CSS property to the column index multiplied by the column width and gutter.
• Set the "top" CSS property to the height stored in the array for the selected column.
• Update the column height (array value) by adding the pin's height to it.

By adhering to these steps, it is possible to create a layout that mimics Pinterest's responsive behavior and efficient pin placement algorithm.
