With a Sharepoint Calendar the events with a long title/description are cropped and you cannot see the full description, except if you move your mouse over it.
Example:

So I’ve had to do some CSS and a complicated JavaScript code to be able to create some large boxes. Now we are able to see the full content title/description of the event.
The result is below:

As you can see, the boxes for the events are now bigger!

To do so, you’ll have to insert the below code into your page:

<style type="text/css">
.ms-acal-rootdiv div {
  overflow: visible;
  white-space: normal;
}
.ms-acal-item { height:auto !important }
.ms-acal-outday { height:100% !important }
</style>

<script type="text/javascript" src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script type="text/javascript">
// load the function after the events are loaded
_spBodyOnLoadFunctionNames.push('changeCalendarEventLinkIntercept');
function changeCalendarEventLinkIntercept() {
  var OldCalendarNotify4a = SP.UI.ApplicationPages.CalendarNotify.$4b;
  SP.UI.ApplicationPages.CalendarNotify.$4b = function () {
    OldCalendarNotify4a();
    setTimeout(function() { showFullEvents() }, 250)
  }
}
// on resize the boxes must be replaced
$(window).on('resize', function() {
  setTimeout(function() { showFullEvents() }, 500)
});

function showFullEvents() {
  var prevPos={bottom:0,left:0};
  var minHeight=0,savedHeight=0,savedMinHeight=0,diffHeight=0;
  var aRows=jQuery('.ms-acal-summary-itemrow');
  
  // set the same size for each row
  aRows.each(function() {
    var h=$(this).outerHeight();
    if (savedMinHeight<h) savedMinHeight=h;
    // save the current height of the row
    $(this).data("saved-height",h)
  }).each(function() { $(this).css("height",savedMinHeight+"px"); });
  
  savedHeight=savedMinHeight;
  
  // move the events
  jQuery('.ms-acal-item').each(function() {
    var $this=$(this);
    var pos=$this.position();
    var height=$this.outerHeight();
    var bottom=pos.top+height;
    minHeight+=height;
    // check if the current event is hover the previous one
    if (prevPos.left === pos.left && prevPos.bottom>pos.top) {
      $this.css("top",(1+prevPos.bottom)+"px")
      bottom += prevPos.bottom-pos.top + 1;
      minHeight+=2;
    }
    // check if we need to make the cell bigger
    if (prevPos.left !== pos.left && savedMinHeight<minHeight) {
      diffHeight=minHeight-savedHeight; // diffHeight will permit to move down all the events later
      savedMinHeight=minHeight;
      jQuery('.ms-acal-summary-itemrow > td').css("height",minHeight+"px")
    }
    if (prevPos.left !== pos.left) minHeight=0
    prevPos={bottom:bottom,left:pos.left};
  })
  
  if (diffHeight>0) {
    var prevDiff=0,diff=0,prevRow=0;
    jQuery('.ms-acal-item').each(function(idx) {
      var $this=$(this);
      // find index that defines the row
      var row=1*$this.attr("_index").split(",")[0];
      if (idx===0 || prevRow!=row) {
        prevDiff=diff;
        diff+=savedMinHeight-aRows.eq(row).data("saved-height");
      }
      if (row > 0) $this.css("top",($this.position().top+prevDiff+2)+"px")
      prevRow=row;
    })
  }
}
</script>

The code could be more clean, but I did that during an evening after a long day of work, so I’m just happy that it’s working. If you’re able to produce a cleaner code, please share it with me!

To give some explanations :

• The CSS permits to wrap the text and make the colored boxes bigger
• The problem starts when there are more than 1 event in a day because the boxes hover each other
• So with JavaScript we have to calculate which boxes are hover the others, and then move them down
• But if you move the boxes, you also have to make the cells bigger…
• And if the cells are bigger, then you need to move down the events/boxes that are in the below row
• And finally, when the window is resized, Sharepoint is moving them around, so the script has to execute again after a resize.

Tested only with Sharepoint 2010, with IE7+, Firefox and Chrome.
