You may want to go through your css and remove some of the errors that are there. As you may already know, if you forget to close out a line, or if you add in an extra bracket, or anything it will cause other parts of your css to malfunction. For example, I saw this on line 2183 –
.says {display:none;}
}…which is obviously one too many brackets. So make sure and fix that and any others that you find. I’d recommend running your site through a validator so it can locate all of the errors for you. Give this a try first – http://csslint.net/ and you can use W3c if you want as well.
I didn’t see the <div id="homequadbox"> code in your source…but even when I added it, it didn’t have an effect. Although when I copy/pasted the css code for #homequadbox at the top of your css (before any of the errors) it worked. I noticed the color of the icon changed. I’m almost certain the reason it’s not working is because you may have some errors. So scan through and hunt down those errors and everything should work again.
Everything is looking good so far 🙂 I’ll add it to the showcase if you can let me know when you’re done with it – http://appfinite.com/showcase-your-site/
