Validating website 1911 serial number dating
I’ve included some screenshots at the bottom of this post to show the full code I used to check under each doctype.

Let’s face it no one can really list every potential show stopping error where search engines are concerned.
The safest thing to do in that case is fix all your errors or as many as realistically possible.
One of the discussions that arises from time to time in web development circles is that of validating your code. It’s no different than comparing a sentence you write to the rules of grammar for the language you wrote it in.
Some will insist your pages need to validate 100% and others will tell you it’s not even worth checking as long as your pages work. In fact the grammar analogy is a good one to keep in mind when you think of validating your code.
Sometimes when you run a page through a validator the list of errors seems so large that it looks like it will take days to fix them.
Often a few simple errors are leading to many more.
Browsers won’t care much either as they’ll typically render much invalid code perfectly fine. Still there are good reasons to validate your code.There are plenty of browser extensions that will test the page you’re viewing in the W3C validators.HTML Tidy is another option for validating pages, though it may not offer the exact same results as the W3C validator.Different browsers may treat invalid code differently and sometimes in unexpected ways.Some will probably tell you that valid code will help your pages rank better. Other than show stopping errors (which validation can help you find) search engines really don’t care much about your code.
