Re: request for DPUB IG review of css-shapes-1

Robert - thanks for the read-through. When digipub sends their response to
www-style, please make sure these comments are included. I’m answering
some here just in case this sparks more questions.

The reason is that the first level of CSS Shapes only applies to floats,
and we don’t want to change floats so much that they become more
complicated than they already are. Floats only wrap around one side.
Adding a shape doesn’t change that, it only changes the contours of that
‘side’.

CSS Exclusions will allow for wrapping around both sides of an element:

I agree that I should add an example showing wrapping around one or more
of the <box> values. The main use case is to allow wrapping around an
element with border-radius defined. Currently, you can add border-radius
to a float, but that does not affect the wrapping behavior (it will still
wrap around the square-corner margin box). If you add
shape-outside:border-box to the float, then content will wrap tightly to
the rounded-corner border. Or if you add shape-outside:margin-box to the
float, then content will wrap around the rounded-corner edge of the margin
box.

Thanks again,

Alan
