你混合了Javascript和Jquery。

使用Jquery,只需使用函数css()

更改css属性
$("#msg").css('visibility', 'visible');

或使用纯Javascript

document.getElementById("msg").style.visibility = "visible";

使用jQuery,您可以使用.css方法,如下所示:

$(document).ready(function () {
  $('#msg').css('visibility', 'visible');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<p>
  <b id="msg" name="msg" style="visibility:hidden; color:#3399ff;">message</b>
</p>

$(document).ready(function(){
$('#msg').css('visibility','visible')
//or: initial	=> Sets this property to its default value
$('#msg').css('visibility','initial')
//or: inherit =>	Inherits this property from its parent element.
$('#msg').css('visibility','inherit')
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p><b id="msg" name="msg" style="visibility:hidden; color:#3399ff;">msg</b></p>
