$("#elementID").css("css-property", "css-attribute");
//On jQuery, the CSS property is typed like normal CSS property

//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
