the unofficial sequel to my CSS shapes article written more than 3 years ago. let's talk a bit about CSS exclusions (and also, specifications, and building demos, and raising bugs) #webdev #css bit.ly/bey-exclusions

For what it's worth, my basic argument against the current exclusions proposal is that they promote the opposite of responsive design: design that's fragile and breaks in response to slight changes in viewport size, fonts, or other variables.

I think that in order for an exclusions model to be responsive, the rules for placement of the exclusions need to have a collision handling model, so that the way you place exclusions involves rules for how to move the exclusion if you put two in the same place.

Floats have this, but absolute positioning doesn't. And I think it's particularly bad in paginated contexts, which is where most of the demos of exclusions focused.
