Input :checked

In CSS, you can query based on the :checked selector for radios and checkboxes to style siblings down the DOM scope. To do this, we can use the ~. It will select same-level siblings after the given selector. Because the tab labels in this demo are nested and not immediate siblings, we will need to select their topmost parent that is at the same level as our input.

To demonstrate, we will do a simplified version of this with a checkbox:

<!-- invisible input and its label -->
<input id="demo-child-toggle" type="checkbox">
<label for="demo-child-toggle">Toggle #demo-child</label>

<-- parent to select first via "~" -->
<div id="demo-parent">
<-- child to select through parent -->
<div id="demo-child">#demo-child</div>

and in our CSS:

/* hiding our checkbox */
#demo-child-toggle {
display: none;  
/* selecting the child */
#demo-child-toggle:checked ~ #demo-parent #demo-child {
color: #c0392b;
font-weight: bold;
text-transform: uppercase;


As you can see, we can control the style of content that comes after a hidden input by toggling it via its label.

At this point you can probably get the picture for how we can conditionally display the tabbed panel content in this pen.

The Tabs

Here is the basic form of a tab in this demo:

<li id="li-for-panel-1">
<label class="panel-label" for="panel-1-ctrl">CSS Radio Toggles</label>

For the “active” tab to cover the bottom border, the child label gets an additional 2 pixels of padding-top while its parent li gets a translateY(1px). This not only covers the bottom border, but gives an ever-so-subtle “moving toward you” effect by shifting the title down 1px.

#panel-1-ctrl:checked ~ #tabs-list #li-for-panel-1 {
transform: translate3d(0, 1px, 0);
#panel-1-ctrl:checked ~ #tabs-list #li-for-panel-1 label.panel-label {
padding-top: 26px; /* instead of "24px" */

Our Partners

On small screens, the tabs fold down into an expandable menu. To trigger the menu, I use a checkbox (note that it appears at the top of the screen on smaller screen sizes). There are two labels that trigger this checkbox. One opens and the other closes the menu. The one that opens is absolutely positioned invisibly over the “active” menu item. The closing label is at the bottom of the open menu.

The best way I have found to show and hide content without using absolute positioning is to use a combination of max-height and opacity. When “inactive”, the content has a max-height: 0 and opacity: 0.

It also has a transition: opacity when I don’t know the future height (this panel’s content for example) and transition: opacity, max-height when I do know the future height (like the menu). When “active”, the max-height and opacity get positive values and the content will transition in. I’m sure flexbox could get me around this hack, but this works for now.
