how to change color of element js code example

Example 1: how to change the color using js

<!DOCTYPE html>
<html>
<head>
<script>
function display()
{
var col=document.getElementById("demo");
col.style.color="#FF0000";
}
</script>
</head>
<body>

<h1>My First JavaScript</h1>
<p id="demo">click on the button below.....</p>

<button onclick="display()">Display</button>

</body>
</html>

Example 2: javascript modify css

//Pure JavaScript DOM
var el = document.getElementById("elementID");
el.style.css-property = "cssattribute";

//When doing A CSS property that have multiple words, its typed differently
//Instead of spaces or dashes, use camelCase
//Example:
el.style.backgroundColor = "blue";

//Make sure before using jQuery, link the jQuery library to your code
//JavaScript with jQuery
//jQuery can use CSS property to fid=nd an element
$("#elementID").css("css-property", "css-attribute");

//On jQuery, the CSS property is typed like normal CSS property
//Example: 
$("#elementID").css("background-color", "blue");

//If you want multiple property for jQuery, you can stack them on one code
//instead of typing each attribute
//Example: 
$("#elementID").css({"css-property": "css-attribute", "css-property": "css-attribute"});

//you can also make them nice by adding line breaks
//Example: 
$("#elementID").css({
  "css-property": "css-attribute",
  "css-property": "css-attribute"});
//You can add as much CSS property and attribute as you want
//just make sure, always end it with a comma before adding another one
//the last property doesn't need a comma
