Why is the deprecated marquee tag supported in code playground?

Question

This tag still works on Sololearn code playground. Is the html we write here not considered html5? Otherwise why is this tag still supported?

Answer 1

The html language used in code playground is not interpreted server side. It uses your phones internal browser. (See webview)

So the question should be: Why does my phones browser still support the marquee tag?

Answer: maybe some website somewhere still might use it?

Answer 2

Thanks jay for the explanation.

Answer 3

To add to jay's answer, some deprecated tags/methods might work for years after being deprecated.
It's up to the browser/engine to remove it or not.
Anyway you should always avoid using code marked as deprecated and update old projects according to current standards.

What is the perfect text editor for a mac computer

Answer 5

No such thing as perfect text editor. All very similar just a matter of preference. I'm a PC person myself and use mostly Microsoft Visual Studio or Sublime bc they have plugins to assist with coding like Emmit (plugin that shortcuts setting up HTML pages by completing code for you.) JetBrains, Net Beans, Notepad++ et c.are others that I've used
