It can make a modal popup window with just HTML an

问题:

I would be interested to know if you can make a modal pop-up window just using HTML and CSS without JQuery.

Does anyone know such a simple example?

Thanks in advance!

回答1:

Yes, it is possible.

You can use the :target pseudo selector to show a modal. Here's an example including some transitions as well (code combined from shehary's codepen example and http://tympanus.net/Development/ModalWindowEffects):

body {
  background-color: #e74c3c;
}

a {
  background-color: #c0392b;
  color: #fff;
  text-align: center;
  width: 200px;
  height: 50px;
  line-height: 50px;
  text-decoration: none;
  border-radius: 2px;
}
a:hover {
  background-color: #a5281b;
}
body > a {
  display: block;
  position: absolute;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
}

.md-modal {
	position: fixed;
	top: 50%;
	left: 50%;
	width: 50%;
	max-width: 630px;
	min-width: 320px;
	height: auto;
	z-index: 2000;
	visibility: hidden;
	transform: translateX(-50%) translateY(-50%);
}

.md-modal:target {
	visibility: visible;
}

.md-overlay {
	position: fixed;
	width: 100%;
	height: 100%;
	visibility: hidden;
	top: 0;
	left: 0;
	z-index: 1000;
	opacity: 0;
	background: rgba(143,27,15,0.8);
	transition: all 0.3s;
}

.md-modal:target ~ .md-overlay {
	opacity: 1;
	visibility: visible;
}

/* Content styles */
.md-content {
	color: #fff;
	background: #e74c3c;
	position: relative;
	border-radius: 3px;
	margin: 0 auto;
}

.md-content h3 {
	margin: 0;
	padding: 0.4em;
	text-align: center;
	font-size: 2.4em;
	font-weight: 300;
	opacity: 0.8;
	background: rgba(0,0,0,0.1);
	border-radius: 3px 3px 0 0;
}

.md-content > div {
	padding: 15px 40px 30px;
	margin: 0;
	font-weight: 300;
	font-size: 1.15em;
}

.md-content > div p {
	margin: 0;
	padding: 10px 0;
}

.md-content > div ul {
	margin: 0;
	padding: 0 0 30px 20px;
}

.md-content > div ul li {
	padding: 5px 0;
}

.md-content a {
	display: block;
	margin: 0 auto;
	font-size: 0.8em;
}

/* Effect */

.md-modal .md-content {
	-webkit-transform: scale(0.7);
	-moz-transform: scale(0.7);
	-ms-transform: scale(0.7);
	transform: scale(0.7);
	opacity: 0;
	-webkit-transition: all 0.3s;
	-moz-transition: all 0.3s;
	transition: all 0.3s;
}

.md-modal:target .md-content {
	-webkit-transform: scale(1);
	-moz-transform: scale(1);
	-ms-transform: scale(1);
	transform: scale(1);
	opacity: 1;
}

<a href="#modal">MODAL</a>

<div class="md-modal" id="modal">
	<div class="md-content">
		<h3>Modal Dialog</h3>
		<div>
			<p>This is a modal window.</p>
			<a class="md-close" href="#">Close me!</a>
		</div>
	</div>
</div>
<div class="md-overlay"></div>

If you don't feel comfortable using visibility: hidden you can use display: none instead. But you better remove the transitions in that case (visibility can be used in a transition, display can't).
