I have been assigned the task of validating a website.
I searched the web and found this post of w3schools that
allows validating the HTML, CSS, XHTML, XML, WML of a website.
My question is, is that all the validation we need to do?
We want our website to be cross-browser and to work well on mobile phones.
Are there any better methods to validate our site?
Thank You.
First of all, w3schools is a terrible website; you’d be better off not using it for anything. For a markup validator, try this or this. Keep in mind that validation only ensures that your markup is syntactically, and to a certain extent, semantically correct, but does not ensure that it’ll render or function how you intend across different browsers, for example. For that, you’ll have to do testing yourself.
