[4.0] Transition of Joomla's wrapper module and component from HTML4 to HTML5 - REVISION

[BaleshSrle]

Revision for Pull Request #20212 .

Summary of Changes

By revisiting my pull request and using site w3schools.com as guide, I made a solution to merge HTML4 and HTML5 elements by leaving Width and Height in HTML4, but scrolling and frameborder are transitioned to HTML5

Testing Instructions

You can use Joomla's current settings for width & height, but you need to modify your settings for borders and scrollbars.

Expected result

To work flawlessly.

Documentation Changes Required

Need to modify 6 files to work without any problems or hiccups:

• modules/mod_wrapper/mod_wrapper.xml

• modules/mod_wrapper/mod_wrapper.php

• modules/mod_wrapper/Helper/WrapperHelper.php

• modules/mod_wrapper/tmpl/default.php

• components/com_wrapper/tmpl/wrapper/default.xml

• components/com_wrapper/tmpl/wrapper/default.php

For future reference - never use w3schools as a source - it is rarely complete or accurate. Much better to use https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe

The option should not be hardcoded CSS. Define it with a variable and compile it in the layout file. Like that the admin has the option to change it in a template override. Gold solution would be to define a class in the template file instead of hardcoded CSS and style it in a CSS file. Like that it is even easier to override by CSS only.

If you know how to do it - be my guest, because I don't.

And by the way, this code works because I'm using my site .::STUDENTI LOGISTIKE@ Saobracajni fakultet Doboj as proving ground for this code (site is created in Joomla! 3.9.6 with modified wrapper module and component by yours truly).

The beauty of this code is that I'm not adding something new (like you are suggesting), I'm modifying the module and component of wrapper (or iframe) element to be compatible with HTML5 standard.

Sorry, but I prefer using https://www.w3schools.com/html/html_iframe.asp & https://www.w3schools.com/tags/tag_iframe.asp
