- Resolution Units: the type
Note that due to the 1:96 fixed ratio of CSS ‘in’ to CSS ‘px’, ‘1dppx’
is equivalent to ‘96dpi’. This corresponds to the default resolution
of images displayed in CSS: see ‘image-resolution’.
A friend of mime (John Hax in the Cc list) complains about this and he seems to think CSS2.1 Issue 149（px vs. pt）[1] should be resolved in favor of the pt-unit proposal (making only 'pt' physical).
The WG resolved that issue already, and I agree with it and won't revisit it for Images. I recommend reviewing the (lengthy) thread about the subject from last year, and if you still disagree, raising the issue with the WG in the context of the Values & Units spec, which is the current defining spec for the px unit.
- Gradients
The two functions described in this section allow an author to specify
such an image in a terse syntax
s/two/four ? Not sure if you want to count repeating-* in.
where , , ,
and are defined in their applicable
sections
below.
For some reason, only gets a xref.
Gradients are a type of image, and can be used anywhere an image
can, such as in the ‘background-image’ or ‘list-style-image’ properties.
This informative paragraph pretty much duplicates everything the following example (13) says and hence I think it can be dropped.
4.1.2. Linear Gradient Examples
Example 19
In the ED, the SVG gave me scroll bars. This was confusing when I first read this via Safari which hides the scroll bars and made me think this picture is wrong. No scroll bars please!
4.3. Repeating Gradients: the ‘repeating-linear-gradient()’ and ‘repeating-radial-gradient()’ notations
(Nitpicking) find the average color of a gradient → find the average color of a gradient for editorial consistency.
5.4. Sizing Objects: the ‘object-fit’ property
In the description of the 'none' value, I think you meant to link "object sizing algorithm" to the algorithm but missed it.
I've made all of these changes.
Please let me know if these resolutions are acceptable.
