  • Start a list from a certain number

    - by Colin
    What's the best way to get a ul to start from 'x'? The start tag is depricated and everything I have found on Google has used the :before pseudo class which doesn't work in IE6 or 7. Didn't have much luck when searching stack either. Only thing I can think of is manually go through and number the lists myself and style accordingly? Any help appreciated.
