javascript - Overlapping elements - HTML, CSS, and jQuery -

-

i have elements overlapping , prevent this. here picture: http://grab.by/cb7t

also, here css elements:

.navigationitem {     background: #808080;     -webkit-border-radius: 360px;     padding: 1.0em;     text-decoration: none;     color: #fff;     position: absolute;     -webkit-box-shadow: 0px 2px 5px #909090;     font-weight: bold;     text-shadow: 1px 1px 2px #707070;     font-size: 1.0em; }

and here in html:

<a href="#" class="navigationitem" id="nav0">play</a> <a href="#" class="navigationitem" id="nav1">register</a> <a href="#" class="navigationitem" id="nav2">our blog</a> <a href="#" class="navigationitem" id="nav4">contact us</a> <a href="#" class="navigationitem" id="nav5">about us</a> <a href="#" class="navigationitem" id="nav6">our rules</a>`

as can see, using them simple styled links using html a tag. reason positions absolute because moving them using jquery:

function moveall() {      for(var = 0; < amount; i++) {         var random = math.random() * 500;         $("#nav" + i).animate({"left": random + + "px"}, "slow");         $("#nav" + i).animate({"top": random + + "px"}, "slow");     } }

when move, though, overlap annoying. how can prevent them overlapping? thank efforts.

removing position:absolute render them side side.

jsfiddle

but if whole point scatter them around randomly, have keep track of positioned elements , take account when calculating position. should save each link's position , calculate every next link's position according previous positioned links. there's no other way when want random positions , non overlapping.

final non-overlapping solution

this working example of non-overlapping functionality. if you'd want links not touch, should change < <= , > >= in if statement condition.

relevant code

var positions = []; $(".navigationitem").each(function(){     var ctx = $(this);     var dim = {         width: ctx.outerwidth(),         height: ctx.outerheight()     };     var success = false;      // repeat positioning until free space found     while (!success)     {         dim.left = parseint(math.random() * 300);         dim.top = parseint(math.random() * 300);         var success = true;          // check overlapping positioned links         $.each(positions, function(){             if (dim.left < this.left + this.width &&                 dim.left + dim.width > this.left &&                 dim.top < this.top + this.height &&                 dim.top + dim.height > this.top)             {                 success = false;             }         });     }     positions.push(dim);     ctx.animate({         left: dim.left,         top: dim.top     }, "slow"); });
