"is this possible?"

Simply, NO.  You have to specify a width and a height for a text box area, and that is fixed.  But look at RICH TEXT AREA -- it might be able to do what you want, you will have to see, the normal text area cannot do it

is there any that runs on the server side that allows you to save the format (somehow) to the database along with the content?

I do not have one at my disposal but
1. capture input when focussing on existing textbox/hide textbox, show div
2. output keystrokes to div and save in hidden textbox

Something like this
function captureIt(cap,field) {
  if (cap) {'none'
      if(!e)return 0;
  else document.onkeydown=null;
<input type="text" onFocus="captureIt(true,this)">
<span id="output" style="display:none"></span>
