将 div 从其位置动画到全屏

Question

I want to expand a div to full screen on clicking on it. Just like this Fiddle js link here

I want to animate the same from its position. if I click the box it feels like expanding from its position please help me to achieve that

 $('.myDiv').click(function(e){ $(this).toggleClass('fullscreen'); });

 .myDiv{background:#cc0000; width:100px; height:100px;float:left:margin:15px;} .myDiv.fullscreen{ z-index: 9999; width: 100%; height: 100%; position: fixed; top: 0; left: 0; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="myDiv"> my div <button>Full Screen</button> </div> <div class="myDiv"> my div 2 <button>Full Screen</button> </div>

Answer 1

Fullscreen animation

Now making a element fullscreen is pretty simple. It could be done with css alone.

 .content { display: inline-grid; width: 150px; height: 100px; background-color: cornflowerblue; border-radius: 3px; transition: width 2s, height 2s; margin: 10px; } .content button { display: inline-block; justify-self: center; align-self: center; height: 2em; } .content:hover { width: 100vw; height: 1200vh; }

 <div class="container"> <div class="content"> <button>Fullscreen</button> </div> </div> <div class="content"></div>

Just adding a transition will make the element brake the layout.
To not break a layout you need:

1. Replace the element. (Below the Visibility : hidden element).
2. Give it an Absolute position.
3. Then set its width to fullscreen and animate its position so it can cover it.
4. Added an animation, transition

 //Function is run on page load $(function() { var full = $(".fullscreen"); //Loops over all elements that have the class fullscreen full.each(function(index, elem) { $(elem).click(fullscreenClick); }); function fullscreenClick() { //The button is this //We want to clone the parent var box = $(this).parent(); //create a holder box so the layout stays the same var holder = $(box).clone(false, true); //and make it not visible $(holder).css({ "visibility": "hidden" }); //Get its position var pos = $(box).position(); //Substitute our box with our holder $(box).before($(holder)); //Set the position of our box (not holder) //Give it absolute position (eg. outside our set structure) $(box).css({ "position": "absolute", "left": pos.left + "px", "top": pos.top + "px", }); //Set class so it can be animated $(box).addClass("fullscreen"); //Animate the position $(box).animate({ "top": 0, "left": 0, }, 3000); } });

 * { margin: 0; padding: 0; } .container { display: inline-block; } .container .element { display: inline-block; background-color: cornflowerblue; margin: 5px; padding: 10px; width: 70px; height: 30px; transition: width 3s, height 3s; ; } .container .element.fullscreen { width: calc(100vw - 30px); height: calc(100vh - 30px); }

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

You can add animation on all styles changes adding next properties to myDiv class:

/* Animate all changes */
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;

I will show the changes on your example:

 $('.myDiv').click(function(e) { $(this).toggleClass('fullscreen'); });

 .myDiv{ background:#cc0000; width:100px; height:100px; float:left: margin:15px; /*Animations*/ -webkit-transition: all 0.5s ease; -moz-transition: all 0.5s ease; -o-transition: all 0.5s ease; transition: all 0.5s ease; } .myDiv.fullscreen{ z-index: 9999; width: 100%; height: 100%; position: fixed; top: 0; left: 0; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="myDiv"> my div 1 <button>Full Screen</button> </div> <div class="myDiv"> my div 2 <button>Full Screen</button> </div>

It's a bit of a complicated task, but this should give you an idea of how it's done. This code will run into some issues (clicking quickly will stack setTimeout ) but does the basics.

The idea is that you calculate the current position of the element with getBoundingClientRect() and set initial position values with that, so that when you adjust the position to fixed , it will look as though it's still in the same spot - then when you override those values with the .fullscreen css, the transition property will allow them to animate.

The biggest issue here, which you'll notice if you click on the first div, is that it disappears from the layout and causes the second div to jump up to where it was, you'd probably need a way of preserving the layout. Hopefully this is helpful as a starting point anyway.

 function getPosition(elem){ const rect = elem.getBoundingClientRect() return { top: rect.top, left: rect.left, width: rect.width, height: rect.height } } function toPx(val){ return [val, 'px'].join('') } $('.myDiv').click(function(e){ if(this.classList.contains('fullscreen')){ this.classList.remove('fullscreen') setTimeout(e => this.style.position = 'static', 1000) //close } else { //open let pos = getPosition(this) this.style.width = toPx(pos.width) this.style.height = toPx(pos.height) this.style.top = toPx(pos.top) this.style.left = toPx(pos.left) console.log(pos) this.classList.add('fullscreen') this.style.position = 'fixed' } });

 .myDiv{background:#cc0000; width:100px; height:100px;float:left:margin:15px;} .myDiv.fullscreen{ z-index: 9999; width: 100% !important; height: 100% !important; top: 0 !important; left: 0 !important; } .animateTransitions { transition: all 1s; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="myDiv animateTransitions"> my div <button>Full Screen</button> </div> <div class="myDiv animateTransitions"> my div 2 <button>Full Screen</button> </div>

Here's how i made it:

• JQuery: 3.6.0
• Css preprocessor: SCSS
• CSS Framework: Bootstrap 5.1.0

See it in action: https://codepen.io/illegalmexican/pen/NWYNVvg

Please note that i was answering a JQuery post. The fowlloing could be made in Vanilla Javascript for better performance. Also keep in mind that this could also be improved in terms of Accessibility standars by having a close button.

Html:

<div class="myDiv-Container">
    <div class="row">
        <div class="col-6">
            <div class="d-flex flex-wrap position-relative">
                <div class="myDiv w-50">
                    <div class="front bg-primary top-left">
                        <h1>Hello<br>World</h1>
                    </div>
                </div>
                <div class="myDiv w-50">
                    <div class="front bg-success top-right">
                        <h1>Hello<br>World</h1>

                    </div>
                </div>
                <div class="myDiv w-50">
                    <div class="front bg-danger  bottom-left">
                        <h1>Hello<br>World</h1>
                    </div>
                </div>
                <div class="myDiv w-50">
                    <div class="front bg-warning bottom-right">
                        <h1>Hello<br>World</h1>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

SCSS:

.myDiv-Container {
  height: 500px;
  width: 500px;
  position: relative;
}

.front {
  position: relative;
  text-align: center;
  display: flex;

  &.position-absolute {
    z-index: 1;
  }

  &.top-left {
    top: 0;
    left: 0;
  }

  &.bottom-left {
    bottom: 0;
    left: 0;
  }

  &.top-right {
    top: 0;
    right: 0;
  }

  &.bottom-right {
    bottom: 0;
    right: 0;
  }
}

JQuery:

document.addEventListener('DOMContentLoaded', function () {
  jQuery('.myDiv').each(function () {
    var frontElem = jQuery(this).find('.front');
    jQuery(this).on("click", function () {
      if (jQuery(this).hasClass('active')) {
        jQuery(this).removeClass('active');
        jQuery(frontElem).animate(
          {
            width: jQuery(this).width(),
            height: jQuery(this).height(),
          },
          500, function() {
            jQuery(frontElem).removeClass('position-absolute');
            jQuery(frontElem).css({
              width: '100%',
              height: '100%',
            });
          });
      } else {
        jQuery(frontElem).css({
          width: jQuery(this).width(),
          height: jQuery(this).height(),
        });
        jQuery(frontElem).addClass('position-absolute');
        jQuery(this).addClass('active');
        jQuery(frontElem).animate({
          'width': '100%',
          'height': '100%',
        }, 500);
      }
    });
  });
