not sure what java script to use

I have an idea for a site that i want to make just for fun. when the site is opened there will be a random background and a random famous quote. so every time the page refreshes i want to the background and the quote to change. how can i do that lets say if i already downloaded a bunch of backgrounds and saved a lot of quotes

Maybe try this?

<body>
    <h1>
        Quotes Go Here
    </h1>
</body>

//Create your arrays
var backgroundImages = ['red','blue','green','yellow'];
var quotes = ['Quote one', 'Quote two', 'Quote three', 'Quote four'];

//Create a function to return a random number
var rand = function() {
    return Math.floor(Math.random()*4); //Change the number 4 for the amount of quotes/backgrounds. you can also use .length to check how many elements in array
};

//Use jquery to do the job
$(document).ready(function() {
    $('body').css('background', backgroundImages[rand()]);
    $('body h1').text(quotes[rand()]);
});
