HTML CSS Modal Popup Problems
I want to modal popups activated by buttons (actually image-links), but I am facing several problems. I am using the W3 Schools example as a starting point - At https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_modal . The first issue is that I want to move the CSS selectors to a linked external CSS file, rather than leave them in the HTML section. But as soon as I move any of the selectors, the activating button dissapears. Sure I must be missing something basic. I have copied the code here - below.
<!DOCTYPE html>
<html>
<head>
<!-- --------------- IF I LINK TO EXTERNAL STYLESHEET BUTTON DISAPPEARS -->
<!-- <link href="css/global.css" rel="stylesheet" type="text/css" /> -->
<meta name="viewport" content="width=device-width, initial-scale=1" />
<style>
body {
font-family: Arial, Helvetica, sans-serif;
}
/* The Modal (background) */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0, 0, 0); /* Fallback color */
background-color: rgba(0, 0, 0, 0.4); /* Black w/ opacity */
}
/* Modal Content */
.modal-content {
background-color: #fefefe;
margin: auto;
padding: 20px;
border: 1px solid #888;
width: 80%;
}
/* The Close Button */
.close {
color: #aaaaaa;
float: right;
font-size: 28px;
font-weight: bold;
}
.close:hover,
.close:focus {
color: #000;
text-decoration: none;
cursor: pointer;
}
</style>
</head>
<body>
<h2>Modal Example</h2>
<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>
<!-- The Modal -->
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<span class="close">×</span>
<p>Some text in the Modal..</p>
</div>
</div>
<script>
// Get the modal
var modal = document.getElementById("myModal");
// Get the button that opens the modal
var btn = document.getElementById("myBtn");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks the button, open the modal
btn.onclick = function () {
modal.style.display = "block";
};
// When the user clicks on <span> (x), close the modal
span.onclick = function () {
modal.style.display = "none";
};
// When the user clicks anywhere outside of the modal, close it
window.onclick = function (event) {
if (event.target == modal) {
modal.style.display = "none";
}
};
</script>
</body>
</html>I'll bring up the second issue when I get this bit sorted.
Thanks in advance
