Invalid HTML warning
I sometimes screw up the spelling of a [blockquote] (using [ instead of < for the example only) or forget a "/" when I want to close a set of italics or bold etc etc. This causes El Reg to flag the post as containing invalid HTML, which is good.
However, some of my posts are long, and/or sometimes quite late at night/early in the morning for me, and in my bleary-eyedness I find it hard to spot the actual error.
Could we have something where the offending code is flagged up in red? Even an approximation of the area if the system is unsure?
Or, if that takes more work to code than I think , how about flagging our html tags in red/underlined/blink/whatever? Being able to spot the valid HTML tags would often make it quick and easy to spot where something was missed. Even better, flag them in different colours - eg [blockquote][/blockquote] in blue, [i][/i] in red and [b][/b] in pink with purple polka dots. Perhaps flagging the respective block, so [i]this is in italics[/i] would also be in red.
