Expanding Circle from center on hover?

Posted 11 June 2013 - 09:33 AM

Hey guys! I would like to create some CSS circles for a nav which would expand from the center of their location, so I figured using CSS transform would be the best way to do this, as making the width and height of the circle would ruin the layout. The thing is, I want the content within the circle, be it text, and icon, whatever, stay the same shape and not be affected by the transform, but i'm having trouble figuring that part out!

Html:
<ul>
    <li><span>one</span>
    </li>
    <li>
        <div>two</div>
    </li>
    <li><span>three</span>
    </li>
</ul>


CSS:
li {
    list-style:none;
    float:left;
    margin-right:20px;
    width:50px;
    height:50px;
    background:blue;
    border-radius:100%;
}
ul > li:hover {
    -webkit-transform:scale(2, 2);
}


here's a fiddle too: http://jsfiddle.net/zRdr7/

Thanks for your help guys, I'm pretty stumped as to the best way to approach this.

Is This A Good Question/Topic? 0

I'm assuming you'd want some sort of JQuery "smooth" rollover type effect, yes?

Yes I am, I was going to use CSS transitions to achieve the effect though. would using mouseover be better than using the hover pseudo?

Well, a CSS hover is only going to enlarge the circle in a split second. Where a JQuery could/would/should allow for a smooth enlarge - where it would seem to "grow", if you will. The effect would appear more - fluid and less rough. Not to mention it would look more "professionally" done.

Just my two cents. ;)

Oh I agree, I was going to append CSS easing using Ceaser to make it smooth. I just need a way to only make the circle get larger without the icons within the circle getting larger. haha

well, if you put the icons in the center into their own "div" or container of sorts, they won't enlarge. It should only be the outer <LI> that expands.... maybe?

So like the number 2 word "two" in the fiddle? http://jsfiddle.net/zRdr7/

Yes, but I'd give those "<span>"s a little styling to help ensure they don't expand - like an exact height/width property. And maybe keep padding or margins at an automatic amount so they stay centered...?
Just a thought.

-stuck some different styling on the div, and on hover the elements still gain size.

WAIT! I think I know! make the inner part the expanding circle, not the <LI>.... style the div to hold the circle, and make IT expand. Put the text into another container within.

Let me try something and get back to you. :)

Not quite it - but... I bet you can tweak it to work.
<html>
   <head>
      <title></title>
      <style type="text/css">
		ul{}
		ul li {
			list-style:none;
			float:left;
			margin-right:20px;
			width:50px;
			height:50px;
		}
		
		div .list{
			background:blue;
			border-radius:100%;
			padding-top:15px;
			padding-bottom:15px;
			text-align:center;
		}
		div .list:hover {
			-webkit-transform:scale(2, 2);
		}
        span
        {
            width: 20px;
            height: 20px;
            color: white;
            font-size: 12px;
        }

            span:hover
            {
                /*-webkit-transform:scale(2, 2);*/
                font-size: 10px;
            }
		
      </style>
   </head>
   <body>
	<div>
		<ul>
			<li>
				<div class="list">
					<span>1</span>
				</div>
			</li>
			<li>
				<div class="list">
					<span>2</span>
				</div>
			</li>
			<li>
				<div class="list">
					<span>3</span>
				</div>
			</li>
		</ul>
	</div>
   </body>
</html>
