I have a menu and three hidden divs that show up depending on what option the user selects. I would like to show / hide them on click using only CSS. I have it working with jquery right now but I want it to be accessible with js disabled. Somebody here provided this code for someone else but it only works with div:hover or div:active, when I change it to div:visited it doesn't work. Would I need to add something or perhaps this isn't the right way to do it? I appreciate any help :)

The thing is my client wants this particular divs to slide/fade when the menu is selected, but I still want them to display correctly with javascript turned off. Maybe z-index could do the trick...?

For a CSS-only solution, try using the checkbox hack. Basically, the idea is to use a checkbox and assign different styles based on whether the box is checked or not used the :checked pseudo selector. The checkbox can be hidden, if need be, by attaching it to a label.

    For some reason I have this obsession with using CSS over java whenever possible, and I like this solution. Anyone else like that too? – Alex Banman Jul 03 '17 at 17:15

    @AlexBanman Yes. I have yet to find a cross-browser, cross-device compatible CSS-only solution I didn't love. – GlennFriesen Aug 30 '17 at 23:15
  • How do you keep the browser from focusing (or attempting to focus) on the checkbox when clicking the label? Using this solution, my browser scrolls to the top of the page when I click the label – froggomad May 01 '19 at 15:57
  • @froggomad You can try using display:none on the checkbox instead of absolute positioning. It definitely seems to alleviate the jumping, but I haven't fully tested it to see if it causes any other issues. – Josh Aug 12 '19 at 16:47
  • @AlexBanman Could you ever use Java to show/hide HTML elements like this? Even when Java was widely supported by browsers, there was no reason to use it for something like this. – Stewart Oct 31 '21 at 22:14
  • @Stewart Unfortunately you'd be surprised just how often I saw Java being used for that. It's 2021 now though, maybe things are different. – Alex Banman Nov 02 '21 at 13:11
  • @AlexBanman If you find a website that still uses Java for anything client-side, it would be one that's been abandoned. I'm not sure when Java ceased to be supported by browsers generally, but going by Wikipedia it seems it happened gradually over 2013-2017. – Stewart Nov 02 '21 at 15:54
  • @Stewart Oh right, there was that. I think that's awesome, I didn't feel like learning Java anyway, and always felt that CSS should be able to do the things I wanted. – Alex Banman Nov 03 '21 at 16:03

This can be achieved by attaching a "tabindex" to an element. This will make that element "clickable". You can then use :focus to select your hidden div as follows...

.clicker {
width:100px;
height:100px;
background-color:blue;
outline:none;
cursor:pointer;
}

.hiddendiv{
display:none;
height:200px;
background-color:green;
}

.clicker:focus + .hiddendiv{
display:block;
}
<html>
<head>
</head>
<body>

<div>
<div class="clicker" tabindex="1">Click me</div>
<div class="hiddendiv"></div>
</div>

</body>

</html>

The + selector will select the nearest element AFTER the "clicker" div. You can use other selectors but I believe there is no current way to select an element that is not a sibling or child.

Although a bit unstandard, a possible solution is to contain the content you want to show/hide inside the <a> so it can be reachable through CSS:

http://jsfiddle.net/Jdrdh/2/

a .hidden {
  visibility: hidden;
}

a:visited .hidden {
  visibility: visible;
}
<div id="container">
  <a href="#">
        A
        <div class="hidden">hidden content</div>
    </a>
</div>

In 2022 you can do this with just HTML by using the details element. A summary or label must be provided using the summary element. details is supported by all major browsers.

<details>
    <summary>Click Here for more info</summary>
    Here is the extra info you were looking for.
</details>

Fiddle to your heart's content

HTML

<div>
<a tabindex="1" class="testA">Test A</a> | <a tabindex="2" class="testB">Test B</a>
<div class="hiddendiv" id="testA">1</div>
<div class="hiddendiv" id="testB">2</div>
</div>

CSS

.hiddendiv {display: none; }
.testA:focus ~ #testA {display: block; }
.testB:focus ~ #testB {display: block; }

Benefits

You can put your menu links horizontally = one after the other in HTML code, and then you can put all the content one after another in the HTML code, after the menu.

In other words - other solutions offer an accordion approach where you click a link and the content appears immediately after the link. The next link then appears after that content.

With this approach you don't get the accordion effect. Rather, all links remain in a fixed position and clicking any link simply updates the displayed content. There is also no limitation on content height.

How it works

In your HTML, you first have a DIV. Everything else sits inside this DIV. This is important - it means every element in your solution (in this case, A for links, and DIV for content), is a sibling to every other element.

Secondly, the anchor tags (A) have a tabindex property. This makes them clickable and therefore they can get focus. We need that for the CSS to work. These could equally be DIVs but I like using A for links - and they'll be styled like my other anchors.

Third, each menu item has a unique class name. This is so that in the CSS we can identify each menu item individually.

Fourth, every content item is a DIV, and has the class="hiddendiv". However each each content item has a unique id.

In your CSS, we set all .hiddendiv elements to display:none; - that is, we hide them all.

Secondly, for each menu item we have a line of CSS. This means if you add more menu items (ie. and more hidden content), you will have to update your CSS, yes.

Third, the CSS is saying that when .testA gets focus (.testA:focus) then the corresponding DIV, identified by ID (#testA) should be displayed.

Last, when I just said "the corresponding DIV", the trick here is the tilde character (~) - this selector will select a sibling element, and it does not have to be the very next element, that matches the selector which, in this case, is the unique ID value (#testA).

It is this tilde that makes this solution different than others offered and this lets you simply update some "display panel" with different content, based on clicking one of those links, and you are not as constrained when it comes to where/how you organise your HTML. All you need, though, is to ensure your hidden DIVs are contained within the same parent element as your clickable links.

Season to taste.

  • Nice, it works, NOTE: TO MAKE SURE YOU CAN CLICK on 'hidden element that appears', you need to set .hiddenDivClass:active{ display: block; } otherwise if you try to click on elements in it, the div will disappear – fruitloaf Jan 12 '23 at 03:17

HTML

<input type="text" value="CLICK TO SHOW CONTENT">
<div id="content">
and the content will show.
</div>

CSS

#content {
  display: none;
}
input[type="text"]{
    color: transparent;
    text-shadow: 0 0 0 #000;
    padding: 6px 12px;
    width: 150px;
    cursor: pointer;
}
input[type="text"]:focus{
    outline: none;
}
input:focus + div#content {
  display: block;
}
<input type="text" value="CLICK TO SHOW CONTENT">
<div id="content">
and the content will show.
</div>

A little hack-ish but it works. Note that the label tag can be placed any where. The key parts are:

  • The css input:checked+div selects the div immediately next to/after the input
  • The label for said checkbox (or hey leave out the label and just have the checkbox)
  • display:none hides stuff

Code:

<head>
    <style>
        #sidebar {height:100%; background:blue; width:200px; clear:none; float:left;}
        #content {height:100%; background:green; width:400px; clear:none; float:left;}
        label {background:yellow;float:left;}
        input{display:none;}
        input:checked+#sidebar{display:none;}
    </style>
</head>
<body>
<div>
<label for="hider">Hide</label>
<input type="checkbox" id="hider">
<div id="sidebar">foo</div>

<div id="content">hello</div>

</div>
</body>

EDIT: Sorry could have read the question better.

One could also use css3 elements to create the slide/fade effect. I am not familiar enough with them to be much help with that aspect but they do exist. Browser support is iffy though.

You could combine the above effect with javascript to use fancy transitions and still have a fall back. jquery has a css method to override the above and slide and fade for transitions.

  • Tilda(~) mean some sibling after; not next sibling like plus(+).
  • [key="value"] is an attribute selector.
  • Radio buttons must have same name

To string tabs together one could use:

<html>
<head>
<style>
input[value="1"]:checked ~ div[id="1"]{
display:none;
}
input[value="2"]:checked ~ div[id="2"]{
display:none;
}
</style>
</head>
<body>
<input type="radio" name="hider" value="1">
<input type="radio" name="hider" value="2">
<div id="1">div 1</div>
<div id="2">div 2</div>
</body>
</html>

You could do this with the CSS3 :target selector.

menu:hover block {
    visibility: visible;
}

block:target {
    visibility:hidden;
}

You can find <div> by id, look at it's style.display property and toggle it from none to block and vice versa.

function showDiv(Div) {
    var x = document.getElementById(Div);
    if(x.style.display=="none") {
        x.style.display = "block";
    } else {
        x.style.display = "none";
    }
}
<div id="welcomeDiv" style="display:none;" class="answer_list">WELCOME</div>
<input type="button" name="answer" value="Show Div" onclick="showDiv('welcomeDiv')" />

    pls add some information to your answer like what differs it from other answers? why is it correct? why are you doing what your doing? – tung May 01 '18 at 09:47
  • And why are you using javascript when the question explicitly says they're currently using javascript and want a CSS only solution... – youcantryreachingme Nov 20 '19 at 21:51

if 'focus' works for you (i.e. stay visible while element has focus after click) then see this existing SO answer:

You're going to have to either use JS or write a function/method in whatever non-markup language you're using to do this. For instance you could write something that will save the status to a cookie or session variable then check for it on page load. If you want to do it without reloading the page then JS is going to be your only option.

With this method, when you click on Nav Dropdown elements it will NOT disappear, unlike plain :focus solution.

key is:

  • tabindex in parent element
  • parentDiv:focus-within hiddenDiv { display: block;}
  • it will work with both: display and visibility css;

HTML code:

        <div className="DevNavBar dbb">
            {/* MAKE SURE TO ADD TABINDEX TO PARENT ELEMENT, OTHERWISE FAILS */}
            <div className="DevNavBar_Item1 drr" tabIndex="0">
                item1
                <div className="DevNavBar_Item1_HiddenMenu dgg">
                    <ul>
                        <li>blah1</li>
                        <li>blah2</li>
                    </ul>
                </div>
            </div>
        </div>

CSS code:

.DevNavBar {
    padding: 40px;
}

.DevNavBar_Item1 {
    padding: 20px;
    width: fit-content;
    cursor: pointer;
    position: relative;
}

.DevNavBar_Item1:hover {
    color: red;
}

.DevNavBar_Item1_HiddenMenu {
    display: none;
    position: absolute;
    padding: 10px;
    background-color: white;
    z-index: 10;
    left: 0;
    top: 70px;
}

.DevNavBar_Item1:focus {
    color: red; // this is so that when Nav Item is opened, color stays red
}

.DevNavBar_Item1:focus-within .DevNavBar_Item1_HiddenMenu {
    display: block;
    color: black; // this is to remove Bubbling, otherwise it will be RED, like the hover effect
}

    I share your concern that this answer looks like spammy. The opening line is all about your youtube video/channel. To make it less spammy, you might offer your disclosure and hyperlink lower in the answer so that the focus is on your actual insights and code. Some trailing text on your answer might be like "I've created a youtube video about the above approach: [hyperlink]" – mickmackusa Jan 12 '23 at 23:43

CSS does not have an onlclick event handler. You have to use Javascript.

See more info here on CSS Pseudo-classes: http://www.w3schools.com/css/css_pseudo_classes.asp

a:link {color:#FF0000;}    /* unvisited link - link is untouched */
a:visited {color:#00FF00;} /* visited link - user has already been to this page */
a:hover {color:#FF00FF;}   /* mouse over link - user is hovering over the link with the mouse or has selected it with the keyboard */
a:active {color:#0000FF;}  /* selected link - the user has clicked the link and the browser is loading the new page */
