指定JavaScript警报框消息的字体大小

Question

I have to show the message on alert box with font size - 6. I have done like below.

     var str = "Formatting some text.";
     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.")

Answer 3

Use this code. It will help

HTML

  <p style="font-size:6px">Formatting some text.</p>
</div>

JavaScript

$( function() {
  $( "#Custom_Alert" ).dialog();
} );
