Could someone tell me how do I make the font size a 12?

<form><textarea rows="15" cols="180" style="background:#000000; font-family:times new roman; color:#af00dd; border:1px solid #8991ff; scrollbar-face-color : #000000;
scrollbar-highlight-color : #8991ff;
scrollbar-3dlight-color : #000000; scrollbar-shadow-color : #8991ff;
scrollbar-darkshadow-color : #000000; scrollbar-track-color : #000000;
scrollbar-arrow-color : #8991ff;">TEXT
</textarea></form>
Thanks

To the style area, add font-size: 12pt;

Thank you.
