Clicking to center div elements

When clicking on my div elements, they transform into flipcards and expand to a size of 600px by 600px. I want these divs to be centered in the middle of the screen when clicked, and then move back to their original position when clicked again. I've been searching for a solution but haven't found one that works. Most suggestions involve CSS properties like:

.flip.cover.flipped{
    left: 50%;
    margin-top: -300px;
    margin-left: -300px;
    position: absolute;
    height: 600px;
    width: 600px;
    top: 50%;
}

I tried adding this CSS to the existing .flip.cover.flipped class that is toggled with Javascript onClick, but it didn't center the divs as expected. Here's the full .flip.cover.flipped class:

.flip .cover.flipped {
    left: 50%;
    margin-top: -300px;
    margin-left: -300px;
    position: absolute;
    height: 600px;
    width: 600px;
    top: 50%;
    transform: rotatey(-180deg);
        -moz-transform: rotatey(-180deg);
        -ms-transform: rotatey(180deg);
        -o-transform: rotatey(-180deg);
        -webkit-transform: rotatey(-180deg);
    z-index: 10;
}

Other solutions involved using custom JavaScript functions, which I couldn't test out. If a JavaScript function is needed, I just need a simple toggle mechanism like

$(this).find('.cover').toggleClass('flipped');
.

Any assistance on achieving this behavior would be greatly appreciated.


In my recent exploration, I realized that the usual methods center the element within its parent, whereas I require it to be centered within the window, not just the parent element.
Here's the HTML structure:

<div class="flip">
    <div class="cover">
        <div class="face front">
            <img src="http://farm4.staticflickr.com/3809/8814925510_b53d082ea6_o.jpg" width="125"/>
        </div>
        <div class="face back">
            Hello World!
        </div>
    </div>
</div>

And here's the JavaScript code to toggle the class:

$('.flip').click(function() {
    $(this).find('.cover').toggleClass('flipped');
});

Edit: In case the example link changes, below is the full code along with the result:

Answer №1

Your flip animation may require some additional tweaking, but I believe I have resolved the centering issue.

View Working Example Here

$(function () {
    $('.flip').click(function () {
        $(this).find('.cover').toggleClass('flipped');
        adjustCenter();
    });
    
    adjustCenter = function () {
        var windowHeight = window.innerHeight / 2,
            windowWidth = window.innerWidth / 2,
            contentHeight = 300,
            contentWidth = 300,
            pageTopPosition = windowHeight - contentHeight,
            pageLeftPosition = windowWidth - contentWidth;
        
        if ($('.cover').hasClass('flipped')) {
            $('.flipped').css({
                position: "absolute",
                top: pageTopPosition,
                left: pageLeftPosition
            });
        } else {
            $('.flip, .cover').removeAttr('style');
        }
    };
    
    $(window).resize(adjustCenter);
});

Answer №2

While I wouldn't say I'm a pro, you could give Jquery a shot :)

Start by making a .centermybox DIV.

Stylesheet:

.centermybox{
      position:absolute;
      left:50%;
      top:50%;
      z-index:99;
      margin: -300px 0 0 -300px;
}

Jquery Script :

$(document).ready function() {
     $(".youdivhere").toggle( function() {
         $(this).addClass(".centermybox"); 
     });
});

Answer №3

I noticed two issues

  1. The flip div has a position:relative, causing the cover to be absolute to it instead of the shelf.

  2. The margin-left and margin-top values are not calculated correctly. They should be adjusted based on screen and modal size.

Here is a method to center a div using jQuery

The correct functionality of this solution depends greatly on point 1 mentioned above

Answer №4

Here's a suggestion for your code:

body {
  height:100%;
}

For the flipped class, you can try this (make necessary changes):

position:absolute;
top:50%;
left:50%;
margin-top:-300px;
margin-left:-300px;

If you want to animate the motion using javascript/jQuery, go ahead and do so. If you need help with that, feel free to ask.

Check out this working example on jsFiddle here.

Consider using margins for spacing between each element instead of adding another element.

To simplify your jQuery click function, you can try this:

$('.flip').click(function() {
    var midHeight = window.innerHeight/2;
    var midWidth = window.innerWidth/2;
    $(this).find('.cover').toggleClass('flipped').css({
        "position":"absolute",
        "top":midHeight,
        "left":midWidth,
        "margin-top":"-300px",
        "margin-left":"-300px"
    });
});

Proof that it works on jsFiddle here. Remember to adjust calculations when window is resized.

Don't forget to revert position back to its original value on the next click.

If you're struggling with implementing these suggestions, check out this fully functional jsfiddle here. You should be able to make adjustments accordingly.

For transitioning animations, I made an approximation in this jsFiddle here. Feel free to experiment for better results.
