     str = str.fontsize("6").fontcolor("#006400").bold();
     alert(str);

But the output get as
<b><font color="#006400"><font size="6">Formatting some text.</font></font></b> Please help to correct the issue

Answer 1

I think No as per my knowledge as this is controlled by the browser

You would have to use a JavaScript based dialog windows alternative like jQuery UI Dialog .

there is another alternative to jQuery UI Dialog box is sweetalert

Answer 2

It is possible to set bold text at alert()

 alert("𝗙𝗼𝗿𝗺𝗮𝘁𝘁𝗶𝗻𝗴 𝘀𝗼𝗺𝗲 𝘁𝗲𝘅𝘁.")
