Debugging and user aids come in 2 flavours:

1. css breakpoints, page and form labels. These can be toggled on or off using the debug button, found top left of the browser window.
2. edit-article and edit-image links allow immediate editing of content. These display no matter the state of the debug toggle.

The aids display only if you’re logged in.
On this site they are displayed for all, but don’t link any where…
