 Hello,

 After deactivating all plugins and switching to Twenty Seventeen theme, I
 can see a huge quantity of warnings.

 The type attribute is unnecessary for JavaScript resources.

 and

 The type attribute for the style element is not needed and should be
 omitted.

 After a Google search, I have found some pages that provide useful
 functions for get rid of the type attribute.

 attribute-from-script-and-style-tags-added-by-wordpress

 https://stackoverflow.com/questions/47906924/remove-type-attribute-from-
 script-and-style-tags-in-wordpress

 The fact is that none of the presented functions remove all the
 type=”text/javascript” and type=”text/css”, for some factors. For example,
 how scripts and styles are enqueued, or if they use single or double
 quotes.

 wp-includes\class.wp-scripts.php

 $tag = "{$cond_before}{$before_handle}<script type='text/javascript'
 src='$src'></script>\n{$after_handle}{$cond_after}";

 Also wp-includes\class.wp-styles.php adds the type=’text/css’ attribute.

 Even if I delete the type='text/javascript' from line 327 I can see that
 default WP Emojis javascript and css style, use type=”text/css” and
 type=”text/javascript”.

 I have two questions:

 1. Has WordPress any plan to get rid of these warnings in order to follow
 W3C guidelines?

 2. Can someone please provide a function in order to remove all these
 warnings? Please, if you don’t care about W3C warnings, do not reply to
 this post.

 Thank you.
