  1. A div is normally only as wide as its container. A blind stab id try using a fixed position or css3 translates. I’d really need to have a play with it to give a correct answer. For SEO benefits you really should be looking at a responsive design.

  2. To take advantage of the benefits from creating terrain from voxels you would need to be exporting to a mesh. If you just wish to generate heightmaps maybe L3DT or World Machine might be the better choice, both come with limited free versions to try.

  3. Yes it is application specific. Until today had never seen an 8bit representation of the alpha channel in a png as i do with say a targa. I did a bit of reading and photoshop is specifically hiding the alpha channel in png’s

     

    From the adobe help desk., Transparency and alpha channels and png

     

    PNG does not support arbitrary alpha channels like other formats such as TIFF. PNG specifies that the fourth channel in a file is transparency, and only transparency. When you open a PNG file with transparency in Photoshop, it is considered a single layer image. It is not a flat background image. Alpha channels can contain anything, while transparency is a specific channel relationship. You can have multiple alpha channels per document, but only one transparency channel. Photoshop handles transparency and alpha channels separately.

  4. Interesting i do not see the alpha channel. The only way i have ever seen this was with a 3rd party application called SuperPNG many years ago. Can you view the alpha channel of the png attached?

  5. PNG's don't support alpha channels, it uses alpha transparency that is part of the png format.

     

    Outputting the diffuse as a targa will give you an alpha channel.
