问题
I've been searching for a good trick to make a Hide/Show content or a list with only CSS and no javascript. I've managed to make this action:
<!DOCTYPE html>
<head>
<style>
#cont {display: none; }
.show:focus + .hide {display: inline; }
.show:focus + .hide + #cont {display: block;}
</style>
</head>
<body>
<div>
<a href="#show"class="show">[Show]</a>
<a href="#hide"class="hide">/ [Hide]</a>
<div id="cont">Content</div>
</div>
</body>
</html>
Demo here: http://jsfiddle.net/6W7XD/ And it's working but not as it should. Here is the problem: When the content is shown, you can hide it by clicking "anywhere on the page". How to disable that? how to hide content "only" by clicking hide? Thank you in advance!

I wouldn't use checkboxes, i'd use the code you already have
DEMO http://jsfiddle.net/6W7XD/1/
CSS
body {
display: block;
}
.span3:focus ~ .alert {
display: none;
}
.span2:focus ~ .alert {
display: block;
}
.alert{display:none;}
HTML
<span class="span3">Hide Me</span>
<span class="span2">Show Me</span>
<p class="alert" >Some alarming information here</p>
This way the text is only hidden on click of the hide element

This is going to blow your mind: Hidden radio buttons.
input#show, input#hide {
display:none;
}
span#content {
display:none;
}
input#show:checked ~ span#content {
display:block;
}
input#hide:checked ~ span#content {
display:none;
}<label for="show">
<span>[Show]</span>
</label>
<input type=radio id="show" name="group">
<label for="hide">
<span>[Hide]</span>
</label>
<input type=radio id="hide" name="group">
<span id="content">Content</span>回答3:
There is 3 rapid examples with pure CSS and without javascript where the content appears "on click", with a "maintained click" and a third "onhover" (all only tested in Chrome). Sorry for the up of this post but this question are the first seo result and maybe my contribution can help beginner like me
I think (not tested) but the advantage of argument "content" that you can add great icon like from Font Awesome (its \f-Code) or an hexadecimal icon in place of the text "Hide" and "Show" to internationalize the trick.

This is what I've used recently.
CSS
div#tabs p{display:none;}
div#tabs p.tab1:target {display:block;}
div#tabs p.tab2:target {display:block;}
div#tabs p.tab3:target {display:block;}
HTML
<div id='tabs'>
<h2 class="nav-tab-wrapper">
<a href="#tab1" class="nav-tab tab1">Pages</a>
<a href="#tab2" class="nav-tab nav-tab-active tab2">Email</a>
<a href="#tab3" class="nav-tab tab3">Support</a>
</h2>
<p id='tab1' class='tab1'>Awesome tab1 stuff</p>
<p id='tab2' class='tab2'>Tab2 stuff</p>
<p id='tab3' class='tab3'>Tab3 stuff</p>
</div>

Hope it helps somewhere.

I used a hidden checkbox to persistent view of some message. The checkbox could be hidden (display:none) or not. This is a tiny code that I could write.
You can see and test the demo on JSFiddle
HTML:
<input type=checkbox id="show">
<label for="show">Help?</label>
<span id="content">Do you need some help?</span>
CSS:
#show,#content{display:none;}
#show:checked~#content{display:block;}
Run code snippet:
#show,#content{display:none;}
#show:checked~#content{display:block;}<input id="show" type=checkbox>
<label for="show">Click for Help</label>
<span id="content">Do you need some help?</span>http://jsfiddle.net/9s8scbL7/

First, thanks to William.
Second - i needed a dynamic version. And it works!
An example:
CSS:
p[id^="detailView-"]
{
display: none;
}
p[id^="detailView-"]:target
{
display: block;
}
HTML:
<a href="#detailView-1">Show View1</a>
<p id="detailView-1">View1</p>
<a href="#detailView-2">Show View2</a>
<p id="detailView-2">View2</p>

I've got another simple solution:
HTML:
<a href="#alert" class="span3" tabindex="0">Hide Me</a>
<a href="#" class="span2" tabindex="0">Show Me</a>
<p id="alert" class="alert" >Some alarming information here</p>
CSS:
body { display: block; }
p.alert:target { display: none; }

A very easy solution from cssportal.com
If pressed [show], the text [show] will be hidden and other way around.
This example does not work in Chrome, I don't why...
.show {
display: none;
}
.hide:focus + .show {
display: inline;
}
.hide:focus {
display: none;
}
.hide:focus ~ #list { display:none; }
@media print {
.hide, .show {
display: none;
}
}<div><a class="hide" href="#">[hide]</a> <a class="show" href="#">[show]</a>
<ol id="list">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ol>
</div>回答9:
I know it's an old post but what about this solution (I've made a JSFiddle to illustrate it)... Solution that uses the :after pseudo elements of <span> to show/hide the <span> switch link itself (in addition to the .alert message it must show/hide). When the pseudo element loses it's focus, the message is hidden.
The initial situation is a hidden message that appears when the <span> with the :after content : "Show Me"; is focused. When this <span> is focused, it's :after content becomes empty while the :after content of the second <span> (that was initially empty) turns to "Hide Me". So, when you click this second <span> the first one loses it's focus and the situation comes back to it's initial state.
I started on the solution offered by @Vector I kept the DOM'situation presented ky @Frederic Kizar
HTML:
<span class="span3" tabindex="0"></span>
<span class="span2" tabindex="0"></span>
<p class="alert" >Some message to show here</p>
CSS:
body {
display: inline-block;
}
.span3 ~ .span2:after{
content:"";
}
.span3:focus ~ .alert {
display:block;
}
.span3:focus ~ .span2:after {
content:"Hide Me";
}
.span3:after {
content: "Show Me";
}
.span3:focus:after {
content: "";
}
.alert {
display:none;
}

The answer below includes changing text for "show/hide", and uses a single checkbox, two labels, a total of four lines of html and five lines of css. It also starts out with the content hidden.
Try it in JSFiddle
HTML
<input id="display-toggle" type=checkbox>
<label id="display-button" for="display-toggle"><span>Display Content</span></label>
<label id="hide-button" for="display-toggle"><span>Hide Content</span></label>
<div id="hidden-content"><br />Hidden Content</div>
CSS
label {
background-color: #ccc;
color: brown;
padding: 15px;
text-decoration: none;
font-size: 16px;
border: 2px solid brown;
border-radius: 5px;
display: block;
width: 200px;
text-align: center;
}
input,
label#hide-button,
#hidden-content {
display: none;
}
input#display-toggle:checked ~ label#display-button {
display: none;
}
input#display-toggle:checked ~ label#hide-button {
display: block;
background-color: #aaa;
color: #333
}
input#display-toggle:checked ~ #hidden-content {
display: block;
}

Just wanted to illustrate, in the context of nested lists, the usefulness of the hidden checkbox <input> approach @jeffmcneill recommends — a context where each shown/hidden element should hold its state independently of focus and the show/hide state of other elements on the page.
Giving values with a common set of beginning characters to the id attributes of all the checkboxes used for the shown/hidden elements on the page lets you use an economical [id^=""] selector scheme for the stylesheet rules that toggle your clickable element’s appearance and the related shown/hidden element’s display state back and forth. Here, my ids are ‘expanded-1,’ ‘expanded-2,’ ‘expanded-3.’
Note that I’ve also used @Diepen’s :after selector idea in order to keep the <label> element free of content in the html.
Note also that the <input> <label> <div class="collapsible"> sequence matters, and the corresponding CSS with + selector instead of ~.
jsfiddle here
.collapse-below {
display: inline;
}
p.collapse-below::after {
content: '\000A0\000A0';
}
p.collapse-below ~ label {
display: inline;
}
p.collapse-below ~ label:hover {
color: #ccc;
}
input.collapse-below,
ul.collapsible {
display: none;
}
input[id^="expanded"]:checked + label::after {
content: '\025BE';
}
input[id^="expanded"]:not(:checked) + label::after {
content: '\025B8';
}
input[id^="expanded"]:checked + label + ul.collapsible {
display: block;
}
input[id^="expanded"]:not(:checked) + label + ul.collapsible {
display: none;
}<ul>
<li>single item a</li>
<li>single item b</li>
<li>
<p class="collapse-below" title="this expands">multiple item a</p>
<input type="checkbox" id="expanded-1" class="collapse-below" name="toggle">
<label for="expanded-1" title="click to expand"></label>
