Pasted code not working in Web code

Question

Recently with the update, I notice that when I try to paste my code into SoloLearn, it doesn't work but when I paste it into another website, it works. Is this a bug?

Answer 1

There are lots of invisible characters in your CSS and Javascript(open the code link in a web browser and see). Remove them and your issue should be fixed.

Answer 2

CR(carriage return)
LF(Line feed)

Answer 3

Not necessarily there may be some invisible characters which may cause issues running the code.
Include your code so we may check.
or paste that pasted code(from codeplayground) in below site it will display invisible characters.

Thank you! Turns out, SoloLearn wasn't the problem but my Memo app keeps turning the tab space into invisible characters.

What does CR and LF mean?
