I'm having trouble putting the mosaic of the example below into the mobile version of my site
The version in orientation:portrait
should be something like this:
..........................
. | .
. Img 1 | .
. | .
...........| Img 3 .
. | .
. | .
. Img 2 | .
..........................
And when the site is placed in landscape
I want them to stay in 3 columns like this:
...........................
. | | .
. | | .
. Img1 | Img 2 | Img 3 .
. | | .
...........................
On the images what size should they be?
