Grid header design - space and shadow

I would like to change the grid on the home. Between images, a distance of about 10 px to be and each image should be deposited with a shadow. Is it possible to adjust the CSS and where do I do that? Thank you Ilona

Hi,

It will be a problem with shadows, because the blocks uses border property for creating spaces between the grid elements.

Thanks for the quick reply. I've seen that I can changeable the margin in the Grid module. But I wanted between each image up, down, left and right a distance. I think that's only with a padding. Can I enter this in the grid? Thank you Ilona

You can specify the border property in the module settings, which will be used for each block in the grid.
