My first problem was about the fiddle not working. Now it works, but if I copy it into my brackets file it doesn't work anymore. I did include the link that I placed in the external resource. Here's the fiddle: https://jsfiddle.net/wtbdxx2b/6/
And the html;
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="site3.css">
<link href="https://fonts.googleapis.com/css?family=Lato:300" rel="stylesheet">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script type="text/javascript" src="site3.js"></script>
</head>
<body>
<button class="trigger">
click
</button>
<div class="content">
hello
</div>
</body>
</html>
the css;
.content {
position: absolute;
width: 100%;
height: 10%;
bottom: 0;
left: 0;
background-color: #000;
color: #FFF;
transition: all 1s;
}
.content.open {
height: 90%;
}
and the javascript;
$(".trigger").click(function() {
$(".content").toggleClass("open");
});
Put
$(".trigger").click(function() {
$(".content").toggleClass("open");
});
Inside
$(document).ready(function(){
$(".trigger").click(function() {
$(".content").toggleClass("open");
});
});
