Yes, but the linked part of the CSS 2.1 spec states of identifiers used
in CSS, including class names used in class selectors, that "they cannot
start with a digit, or a hyphen followed by a digit".
So when I originally stated that "12345 is a valid value for the class
attribute" (or words to that effect) I was correct in terms of HTML
4.01, but such a class could not then be the subject of a class selector
in CSS.
No, you just fail to understand *how* to select it. The digit 1 has the
Unicode code position U+0031. Thus, using an escape sequence, the
selector can be written like either of these 2 selectors:
.\31 2345 { color: green; }
.\0000312345 { color: green; }
<p class="12345">This line should be green
