Why Isn't My jQuery CSS Modification Working?

Changing CSS with jQuery

In an attempt to modify CSS elements using jQuery, the code provided seems to lack a crucial element. The jQuery API states that CSS properties can be specified using both quoted and unquoted notation.

Inspecting the code closely, the issue lies in a missing closing curly brace. The line:

$("#myParagraph").css({"backgroundColor":"black","color":"white");

should have an additional curly brace to close the object literal:

$("#myParagraph").css({ "backgroundColor": "black", "color": "white" });

With this correction, the code behaves as intended, altering the styles of the HTML elements:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="bordered">
  <h1>Header</h1>
  <p>

$(init);

function init() {
  $("h1").css("backgroundColor", "yellow");
  $("#myParagraph").css({ "backgroundColor": "black", "color": "white" });
  $(".bordered").css("border", "1px solid black");
}
