How select specific tag in jQuery using if else statement?

I would like to click the button and make the value appear in <h3> inside the <div> and according to that value the background-color would change.

For example, when I typed a value (Your number) and clicked on Click Me!, h3 inside the div should show this typed value and the background-color would also change accordingly.

For example, if I typed 33 in Your number and then clicked, the value to appear would be 33 and the color would be orange. Thus:

My code:

<script src=//ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js></script><form name=myform> Your number: <input type=text name=inputbox id='textBox' value="" /> <input type=button name=button value="Click me!" /> <div class='box1' style='background-color:lime;width:33.33%;padding-left:15px;padding-right:15px;'> <h3> 0 </h3> <p> Valor </p> </div></form><script> $(function() { $('.member').click(function() { var answer = $("#textBox").val(); if (answer <= 20) { $('.box1').css('background-color','red'); } else if (answer <= 50) { $('.box1').css('background-color','orange'); } else { $('.box1').css('background-color','steelblue'); } }); });</script> 

So I wanted to select the h3 tag and change it with if else statement.
