HTML How to Make a Website Responsive Web Design and Testing Website Testing

How come when I test my index.html code on the web through the 43-validator, it comes back with error messages?

When I test my index.html code on the w3-validator it comes back with many error messages. I followed your code through and through and have no existing problems notifying me in workspace that my code is neither unfinished or any of the opening and closing tags are out of place so why would this happen? Would these error messages in the future prevent me from making my website live?

The W3 standards can change. New elements may replace old ones that become deprecated. This won't impede you from making your website live, but you should strive to follow the W3 standards because they know what's good for you and your users. =) Do a web search like : "(error name) w3 validation not working" and you should find some useful advice. =)
