CSS3 transform on click using pure CSS

I'm trying to get an image (a plus symbol) to rotate 45 degrees to create a cross symbol. I have so far managed to achieve this using the code below but its working on hover, I wanted to have it rotate on click.

Is there a simple way of doing so using CSS?

My code is:

CSS

img {
    display: block;
    margin: 20px;
}

.crossRotate {
    -webkit-transition-duration: 1s;
    -moz-transition-duration: 1s;
    -o-transition-duration: 1s;
     transition-duration: 1s;
    -webkit-transition-property: -webkit-transform;
    -moz-transition-property: -moz-transform;
    -o-transition-property: -o-transform;
     transition-property: transform;
}

.crossRotate:hover {
    -webkit-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
     transform: rotate(45deg);
}

HTML

<body>
   <img class="crossRotate" src="images/cross.png" alt="Cross Menu button" />
</body>

Here is the jsfiddle demo.

You can use WebkitTransform along with Transition (transition: all 2s;) to make the desired rotation with animation.

<style> 
div.a {
  width: 150px;
  height: 80px;
  background-color: yellow;
  transition: all 2s;
  
}
</style>

<div class="a" id="box">Your Image Here</div>

<button onclick="rotate()">Rotate </button>

<script>

function rotate()
{
   x= document.getElementById("box");
  
  x.style.WebkitTransform = 'rotate(' + 20 +'deg)';
}

</script>

The advantage with this method is that you can do it programmatically. You can specify the angle using javascript (Although this is not required in your partcular case).

Voila!

div {
  background-color: red;
  color: white;
  font-weight: bold;
  width: 48px;
  height: 48px;  
  transform: rotate(360deg);
  transition: transform 0.5s;
}

div:active {
  transform: rotate(0deg);
  transition:  0s;
}
<div></div>

You can also affect differente DOM elements using :target pseudo class. If an element is the destination of an anchor target it will get the :target pseudo element.

<style>
p { color:black; }
p:target { color:red; }
</style>

<a href="#elem">Click me</a>
<p id="elem">And I will change</p>

Here is a fiddle : https://jsfiddle.net/k86b81jv/

Method #1: CSS :focus pseudo-class

As pure CSS solution, you could achieve sort of the effect by using a tabindex attribute for the image, and :focus pseudo-class as follows:

<img class="crossRotate" src="http://placehold.it/100" tabindex="1" />

.crossRotate {
    outline: 0;
    /* other styles... */
}

.crossRotate:focus {
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

WORKING DEMO.

Note: Using this approach, the image gets rotated onclick (focused), to negate the rotation, you'll need to click somewhere out of the image (blured).

Method #2: Hidden input & :checked pseudo-class

This is one of my favorite methods. In this approach, there's a hidden checkbox input and a <label> element which wraps the image.

Once you click on the image, the hidden input is checked because of using for attribute for the label.

Hence by using the :checked pseudo-class and adjacent sibling selector +, we could get the image to be rotated:

<input type="checkbox" id="hacky-input">

<label for="hacky-input">
  <img class="crossRotate" src="http://placehold.it/100">
</label>

#hacky-input {
  display: none; /* Hide the input */
}

#hacky-input:checked + label img.crossRotate {
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

WORKING DEMO #1.

WORKING DEMO #2 (Applying the rotate to the label gives a better experience).

Method #3: Toggling a class via JavaScript

If using JavaScript/jQuery is an option, you could toggle a .active class by .toggleClass() to trigger the rotation effect, as follows:

$('.crossRotate').on('click', function(){
    $(this).toggleClass('active');
});

.crossRotate.active {
    /* vendor-prefixes here... */
    transform: rotate(45deg);
}

WORKING DEMO.

If you want a css only solution you can use active

.crossRotate:active {
   transform: rotate(45deg);
   -webkit-transform: rotate(45deg);
   -ms-transform: rotate(45deg);
}

But the transformation will not persist when the activity moves. For that you need javascript (jquery click and css is the cleanest IMO).

$( ".crossRotate" ).click(function() {
    if (  $( this ).css( "transform" ) == 'none' ){
        $(this).css("transform","rotate(45deg)");
    } else {
        $(this).css("transform","" );
    }
});

As jeremyjjbrow said, :active pseudo won't persist. But there's a hack for doing it on pure css. You can wrap it on a <a> tag, and apply the :active on it, like this:

<a class="test">
    <img class="crossRotate" src="images/cross.png" alt="Cross Menu button" />
 </a>

And the css:

.test:active .crossRotate {
    transform: rotate(45deg);
    -webkit-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    }

Try it out... It works (at least on Chrome)!

You can use JavaScript to do this, with onClick method. This maybe helps CSS3 transition click event
