This is a simple semi-monochromatic 3 column fixed width skin for Sandbox-10.

It doesn’t matter if you have widgets or using the default sidebar, all elements should look consistent.

The posts column has a width of 575 pixels so, it is recommended to use images no bigger than 500px wide. The side bar has a width of 200px, so images bigger than 180px are not recommended.

This skin is also compatible with Sandbox 1.2 on self-hosted blogs.
