The Responsive Slideshow Photo Gallery has a fluid / flexible / responsive layout. Basically the grid is added into a html page into a div of your chosing and it's adapting based of that div's width, the grid height is modified based on the number of thumbnails and if other elements are below the grid div they will be pushed down automatically (document flow). In the examples provided you can see a few ways in which you might use this grid, of course that other configurations are possible (please note that the code of this examples is provided in the download files). Pure OOP JavaScript code, no usage of jQuery or other libraries, in this way there will be no incompatibilities with HTML pages that might be using jQuery or other JavaScript libraries.
