I need someone to repair the stylesheet on a website. I wrote it using CSS3 and responsive sizing about a year ago and the client wants backwards browser compatibility. I like it. I think that anyone using a browser old enough to cause problems with this site doesn't deserve the internet. But I'm a web developer not a front end guy. I have very little knowledge concerning browser css compatibility. I'm solely back end and I work full time. I don't have time to learn the ins and outs. Can you help?
