1 final stage ought to be produced here concerning CSS and the existing “version 3” packaging. Although this kind of does appear to imply there will 1 day be considered a “CSS4, ” Tabs Atkins, an associate of the CSS Functioning Group, has mentioned there are simply no programs for this. Rather, 

when he clarifies, the specification offers been broken into individual segments, each using its own edition quantity. So you may see something similar to “CSS Color Module Level 4”-but that will not refer to “CSS4. ” Regardless of what level a person module reaches, it'll still technically be beneath the umbrella of “CSS3, ” or even better, simply “CSS.
