hi. i'm not sure where to start, so i'll just dive right in. i'm building a website right now for work and until recently i had been using the quirks mode doctype, using IE 6 for 95% of the development. periodically though, looking at the site in nn4.7, moz 1.0, nn6.2, and opera 6.03 and trying to make any corrections i can. in quirks mode moz, nn6.2, opera6.03, and ie6 load the page fine. (nn4.7 looks like crap.) in standards mode nn6.2, opera, nn4.7(understandably) and ie6 look exactly the same as they did before. moz, however looks a lot different. in cells where there should be nothing and they should be collapsed, there is now a large space as if a is occupying the cell. my problem is with mozilla in standards mode. i'd like to use standards mode but i'm not sure if it's worth modifying the code i've written so far just to get all the spaces to go away. i'm also not sure what to do about it, hence my writing to theList. please kind sir's(and mam's) if you would take the time to divulge any information you've got regarding anything in this email i'd appreciate it greatly. i'd also like to hear opinions on what people think is more worthwhile. going with standards mode and trying to get it to work, or continue in quirks mode and try to reach the broadest audience as possible with as nice a looking website as possible. thanks for the input, chris.  from what i've read, quirks mode is achieved by using <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> as your doctype instead of the full correct doctype which is <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd"> and puts the browser into standards mode.  opera does some funky left aligning of a menu which i have yet to investigate.  not being an expert with what the w3c says about this and how mozilla follows their recommendation, i'm assuming that when a cell is defined as <td></td> in your html it should not look on screen as if it is defined as <td> </td>. let me know what the truth about that is though.  why do i want to use standards mode? well i guess i don't have a good reason (or any reason at all) other than i'd like to more closely follow the standards.
