CSS - Do I Need To Worry About Hacks?

I am looking for a reputable source which suggests that CSS hacks are not good practice and should be avoided... Ive tried W3C and W3schools seem to be struggling to find any solid info any help would be appreciated...

Thanks in advance

I've got my hover effects to work in Firefox, Opera , and all...except for IE.

I've done searches for a hack, but can't seem to find anything...

Example

Disregard the layout and dead links, etc.

Any help is appreciated...

Thanks

hi.

looking for a good book to learn css, which does *not* labor ie6 hacks, since none of my readers use ie6 any longer.

i have read the head first book on xhtml/css, and now looking to expand my knowledge on css to include strong fundamentals, so i can move onto more cutting-edge stuff.

a friend recommended css mastery, but this book was published in feb 2006, and ie7 was released nov 2006, so i don't see how it could be considered applicable to current browsers.

there are so many to choose from.

again i'm looking to learn strong fundamentals, without the need to spend time learning ie6 hacks.

thanks.

Hi all, a few quick q's:

1. What is best way to set-up a style-sheet for NN4 CSS? I am using @import, and I want to serve-up a NN4 CSS with link a "link rel"...

2. Can I reley upon Dreamweaver's CSS syntax checking to create my alternative/NN4 CSS? (i.e. DW will tell you if a particular attribute or style is or is-not supported by a certain browser.)

3. What is the best/fastest/your technique for building alternative style sheets (by alternative, I mean a style-sheet to feed to browsers like NN4)?

4. Should I be using the TAN hack for height also? Example:
Code:

* html div { /* This is the Tan hack */
    height: 130px; 
    hei\ght: 100px; }
/* the backslash cannot appear before the letters a to f, and A to F, and numerals 0 to 9 since doing so will turn those letters or numerals into hexadecimal numbers. */

5. (Last q) I am using an image replacement technique for my navigation (using one background sprite to create off/over/active states: INKNOISE)... It works great, except this: In Mozilla FF on PC when page loads, the background images do not ussually load... Anyone got a fix for that? Because I can't seem to find a fix, my best answer would be to create a PHP sniffer and force a page refresh.

Thanks in advance!
Cheers!
