A responsive thumbnail grid in Drupal 7 node How to create a responsive thumbnail grid in Drupal node? I need simple thumbnail grid with description under the pictures, without expanding image. Something like this example. All thumbnail containers should have the same size, say 210px x 210px, but size of images can be diffferent. I installed a lot of modules, include Views, Chaos tool suite, Picture, Brilliant Gallery, but it mostly suitable for image galleries, not for simple thumbnail grid.

Is there method to create responsive picture grid without editing templates or altering core? (i.e. adding code directly in the body of 'Article' or 'Basic page' content, while text format is full HTML) I have read Views and Views Fluid Grid modules manual, but got no idea how to use them for this task, not even sure whether this will be suitable for this purpose.
When you get to this level of customization you need to start considering creating your own page/node templates.  

If I was doing this,  my pages for this content would get their own content type,  then I would create a corresponding page template.

Inside that page template, I would then load the raw data for the node, using node_load  and then access the fields directly and put them inside the appropriate markup.
