How to show / hide multiple elements at the same time with javascript

Question

So, I have this between my head tags

Answer 1

The JavaScript is executed before the divs are in the DOM. The standard way to do something after the DOM is ready is to use jQuery's $(document).ready(function () { });, but there are other ways as well.

The oldschool way is to use .

Here's a newer way (edit: put display:none into CSS):

HTML:

hello
​

CSS:

.javascript_needed {display:none;}

JavaScript:

​$(document).ready(function () {
    $('.javascript_needed').show();
});
