I got many error HTML code from Nu Html Checker and actually, I don't know much about W3C Standard because I always use Outsystems Drag and drop and don't mind the rule.
I wonder can I change or improve all of them to not error (and warning..)?and how?

and this is the customer link project test in Nu Html Checker
https://validator.w3.org/nu/?doc=https%3A%2F%2Fwww.kinto-th.com%2FHome.aspx

I'm in shock why so many error of them and I was asked  to solve all of this...or should I say NO?

HI Chunyanuch Kimpiam,

I hope you have not used any custom JavaScript or html as you mentioned that you only used drag and drop mostly. You can contact Outsystems support with the error and warning report and they will definitely help you and will provide answers to your queries.

You can either open a support case through their support portal or can directly send an email to support@outsystems.com for any assistance related to the product.
