I’m in the later stages of working on a website, and I previewed it  today for the first time in IE7. It’s… kinda messed up in a lot of  areas. I built it in DW CS4, previewing it in Firefox and IE8. I have  knowledge of HTML and CSS, and I used a mixture of coding and WYSIWYG to  create the site.Here it is: http://www.alpha-lemur.com
It’s  just up to be tested right now, so there’s no actual cart to put  products into or anything, and it’s still unfinished in a lot of ways.  The main pages I’ve had problems with in IE7 are Distributors, the  High-Speed Serial Products part of the Products page, and the fact that  the Products drop-down menu drops across. My question is: how  do I fix the page to work in IE7 and below while keeping the way it  looks now in Firefox and IE8?
I hope that was clear enough. If you  need any of my code, let me know. Thanks in advance!
