I dunno how exactly I can explain my issue or if the title is specific enough. But what I want to do is for example I have a game like Tic Tac Toe and if the game finish a message should pop up the entire screen which block any other interactions except there is a button only. Like that:
I think something with display: ???
Ive made a simple example for you how it could be done:
<head>
<style>
.content {
color: red;
}
.overlay {
z-index: 1;
width:100vw;
height: 100vh;
position: absolute;
top: 0;
left:0;
background-color:black;
opacity: 0.8;
}
.msg {
background-color: white;
width: 70px;
padding: 50px;
font-weight: bold;
text-align:center;
position: absolute;
top:40%;
left: 45%;
}
</style>
</head>
<body>
<p class="content">some content</p>
<div class=overlay>
<p class="msg">TEST</p>
</div>
</body>
</html>
this shows a black overlay over the complete Screen with a "TEST"-Message, you can add more Items like Buttons to the "overlay"-div if you want to.
But keep in mind, to use the "position: absolute;" attribute.
You can show or hide it by setting the "display: none" (hide) css-attribute to the "overlay"-div or setting "display: revert;" to show it
You need to create a fullscreen overlay. Link: https://www.w3schools.com/howto/howto_js_fullscreen_overlay.asp Then you can add a Javascript event so that your quiz restarts when the user clicks the restart button. Hope this helps!
You might want to look at this post, How can I disable an entire HTML page on an event like in the case of JavaScript alert? I found it just by searching your question on Google. You'll probably need to use jquery for the solution.
