Was wondering if someone can help me with this. I want to be able to click the text/icon, and on click, the + icon rotates 45 degrees to look like a x icon. Upon second click, the icon rotates back to look like a + icon, and so on.

Any help will be greatly appreciated!

Succinct with a beautiful animation

Personally, I disliked Louys' overly verbose and uninteresting solution.

Here, with jQuery at our disposal we can create something so much more beautiful:

rotated = false;
$('.pointer').click(function(){
  elem = this;
  
  $({rotation: 225*rotated}).animate({rotation: 225*!rotated}, {
    duration: 500,
    step: function(now) {
      $(elem).css({'transform' : 'rotate('+ now +'deg)'});
    }
  });
  rotated=!rotated;
});

See the JSFiddle or the snippet:

i = 1;
$('.pointer').click(function(){
  elem = $(this).children("img")[0];
  
  $({rotation: 225*!i}).animate({rotation: 225*i}, {
    duration: 500,
    step: function(now) {
      $(elem).css({'transform' : 'rotate('+ now +'deg)'});
    }
  });
  i=!i;
});

.container{
  width:100%;
  padding-top:100px;
  padding-bottom:100px;
  background-color:#000;
  text-align:center;
  font-size:20px;
  color:#fff;
}

.coolImage{
  height:17px;
  width:17px;
  margin-left:7px;
}

.pointer{
  cursor:pointer;
}

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">

<div class="pointer">
CLICK ME<img src="https://i.sstatic/Tgf0C.png" class="coolImage">
</div>

</div>

We jQuery#animate a "fake" object to be able to generate the smooth animation. You can change the duration to something else if you want to speed or slow the animation.

rotated is used as a stand-in variable to provide the toggle functionality.

Please ask if further clarification is needed.

Define a rotated class in you css, then toggle the class on clicks, for example like:

var pointers = document.getElementsByClassName('pointer');
for(var i = 0; i < pointers.length; i++){
	pointers[i].addEventListener('click', function(event) {
  	event.target.getElementsByClassName('coolImage')[0].classList.toggle('rotated');
  });
}

.container{
  width:100%;
  padding-top:100px;
  padding-bottom:100px;
  background-color:#000;
  text-align:center;
  font-size:20px;
  color:#fff;
}

.coolImage{
  height:17px;
  width:17px;
  margin-left:7px;
  transform:rotate(45)
}

.pointer{
  cursor:pointer;
}

.rotated {
  transform: rotate(45deg);
}

<div class="container">

<div class="pointer">
CLICK ME<img src="http://www.ssglobalsupply./images/plus.png" class="coolImage">
</div>

</div>

Here you go with a cross-browser working example:

function rotate() {
   var elm = document.getElementById('imgToRotate');
   var className = elm.className;
   if(className.indexOf('rotate') === -1) {
      elm.className = elm.className + ' rotate';
   } else {
      elm.className = elm.className.replace(' rotate', '');
   }
}

.container{
  width:100%;
  padding-top:100px;
  padding-bottom:100px;
  background-color:#000;
  text-align:center;
  font-size:20px;
  color:#fff;
}

.coolImage{
  height:17px;
  width:17px;
  margin-left:7px;
}

.pointer{
  cursor:pointer;
}

.rotate {
  transform:rotate(45deg);
  /* Firefox */
    -moz-transform:rotate(45deg);
    /* Safari and Chrome */
    -webkit-transform:rotate(45deg);
    /* Opera */
    -o-transform:rotate(45deg);
    /* IE9 */
    -ms-transform:rotate(45deg);
    /* IE6,IE7 */
    filter: progid:DXImageTransform.Microsoft.Matrix(sizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476);
    /* IE8 */
    -ms-filter: "progid:DXImageTransform.Microsoft.Matrix(SizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476)"; 
}

JSFiddle https://jsfiddle/balasuar/jcwg1h71/

I updated your Fiddle with this script:

var rotated = false;
$(".pointer").click(function() {
  if (!rotated) {
    $(this).find("img").css({
      "transform": "rotate(45deg)"
    });
  } else {
    $(this).find("img").css({
      "transform": "rotate(0deg)"
    });
  }
  // Toggle the flag
  rotated = !rotated;
});

Notice That I also added the jQuery lib in the external ressources".

Insert this code into the <img> tag:

onclick="this.style['-webkit-transform'] = 'rotate(' + 45 + 'deg)';"
