Why is the deprecated marquee tag supported in code playground?
This tag still works on Sololearn code playground. Is the html we write here not considered html5? Otherwise why is this tag still supported?
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?
Thanks jay for the explanation.
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
No such thing as perfect text editor. All very similar just a matter of preference.

JetBrains, Net Beans, Notepad++ et c.are others that I've used
