This needs better alignment, should extend the entire block width. It did so in commits pre-commit 250 (SHA-1: 09b7628073bbb880ceae833d3aa0e972ecfa76ce), but then the icon was moved within the block, but the block was not resized. This issue does not seem to affect any other included themes.

Fix in themes/marine/stylesheets/project_website.css line 7 (remove the margin-left).
