How does Facebook write color on the browser console?

Question

I need to do something similar to the image below:

You can see it when you enter the browser console by going to any Facebook page.

I tried to insert HTML into the function console.log(), but it was in vain. Some hint?

Answer 1

You can do it like this:

console.log('%c Espere!', 'color: red; font-size: 20px;');

It is in the second parameter that you put the styles you want.

Answer 2

You can get this feature with the syntax below, where %c activates CSS styles to the message:

console.log('%c Olá!', 'color: red; font-size: 30px;');

Does not work in IE and Edge (in the case of Facebook, the "alert" message displayed in the question is not even displayed in these browsers).
