`font-family: GdnSans, "Futura", "Myriad Pro", "helvetica neue", "gill sans", sans-serif;`

It is important to note for this to work you need a font with all the appropriate weights. I don’t have one but The guardian sans has 9 weights but for some reason only 7 are being used, Futura BT has 5, Myriad pro has 5, Helvetica neue has 4, Gill sans has 3,

You are unlikely to have gardian sans or a futura with 5 weights, I’m not sure how to make a better test case.
