type FloatStack

type FloatStack []*RenderableDomElement

    A FloatStack represents the floating elements that haven't yet been cleared. There's generally two FloatStacks, one for the left elements, and one for the right elements. Once dot advances past the FloatStack, they're removed from the stack.

    func (FloatStack) ClearFloats
