Making a number of reasonable assumptions, a J-value model produces a population-average life expectancy, which may be translated easily into a corresponding life expectancy at birth when life expectancy is not modified by discounting (net discount rate equals zero).The resultant values may be tested against pan-national data, showing a very good match.
It could be a misspelled piece of code or forgotten element the tag or style requires to work properly.That also means that it will be accessible to more people, across more web browsers and operation systems.Having an accessible website is also regarded as good web design practice.The World Wide Web Consortium sets the standards and also hosts a variety of web page validators.In simple terms, validation ensures that your website complies with the standards accepted by most web designers.The J-value is an objective method for determining when life extending measures are sensible, applicable to both manufacturing and service industries, including public health and healthcare.
A model of human decision making based on the J-value is able to explain the shape of the Preston curve that relates life expectancy at birth and gross domestic product (GDP) per head for all the nations in the world.
As you can see, having a validated website has its definite plus points.
Validators detect problems in your web page and style sheet.
If your code contains errors or tags that are not part of the HTML specification, screen readers and other assistive technologies might fail when trying to render the content for users.
Even pages that seem to look fine in a web browser might have unseen problems for assistive technology users.
Validate these page views as well to make sure you cover all the template files.
