when your viewing page source, what does red mean? im pretty sure that it means its wrong but im just double checking.
Orta's answer about the red foward slash for self-closing element is correct. I do think that canyonchase1 is refering to the 'orangered' text as he mentioned "nbsp" of the non-breaking-space
in his comment.
For Firefox, those in orangered are HTML entities excluding the
& (ampersand) prefix and the
; (semi-colon) suffix, e.g.:
- etc etc
Hence these are not errors.
Red is also used to indicate the part of a self closing element in the Firefox view source view, for things like
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
It helps you see that you've remembered to close the tag. Extra useful when writing XHTML
