Website Validity

If you own a website or blog, I strongly recommend you read this article. If you don't own a website or blog, you can read it anyway - it is very informative - it just won't directly apply to you.

So what is "website validity"?
Website validity basically means that a website's is code perfect. This may sound a little odd, so let me explain. When you write the code that makes a website you have to do many different things, the first and foremost though, is to choose which type of code to use. As a perfectly valid XHTML 1.0 strict page, would not be valid as a HTML 4.0 traditional page. Once you have chosen your form of code, you start to build a website. This is where the errors begin to occur. Interested? If so read on!

Why does website validation matter?
If you type a bit of code wrong, it means that browsers and search engines will not be able to read the code, and therefore will not be able to interpret and display it properly. This is why it is really important to make sure the code is right, as you can have a webpage that looks fine code wise, but when you view it on the web it may not look so good - as the faulty code has changed the way it looks.

How can I validate my website?
You can check your website's validity very easily by using an online HTML validator. The best one (in my opinion) is the W3C HTML Validator. W3C also have a CSS Validator and RSS Validator, so you can also check those as it is important that they are valid too.

What next?
After you have validated your pages, most validator's give you a badge that you can put on your site, to show that your site is HTML, or CSS or RSS valid. W3C's badge's vary in colour, so you can pick one that suits your website best. We all make mistakes when updating pages, so don't forget to keep checking that your pages are still valid! At the top are my HTML, CSS and RSS badges.

Thanks for reading, I hope you found this article helpful!
