Responsive Gridfolio has a fluid / flexible / responsive layout. Basically the grid is added to the html page in the div you choose and adjusts based on the width of that div, the height of the grid adjusts based on the thumbnails and if other elements are below the grid div they will automatically be moved down (document flow). In the examples shown you can see several ways you can use this grid, of course other configurations are possible (please note that the code for these examples is included in the downloads).
