Useful Resources
One of my clients recently asked me how I test my websites to check to see if they have any errors and if they are valid or not. Of course my response was "My sites are perfect, there's no need to bother checking."
I pretty much left it at that with them, but I thought I would share a few of my secret resources with you guys. I'm pretty big on cross-platform standards and these are some of the tools I use to ensure this.
