Centering a ul with floated li
I have
<div id="container">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</div>
With the following CSS:
#container li {
float:left;
height:33px;
line-height:30px;
text-align:center;
width:auto;
}
#container{
width:600px;
}
However I am having difficulty in horizontally centering th开发者_如何学编程e ul inside #container
. It appears that I need a fixed width set on the ul for margin: 0 auto
to work (needs text-align: center
for IE). However I do not want to set a fixed width for the ul as the li items will be dynamic.
Please advise.
#container {
width: 600px;
text-align: center;
}
#container ul {
display: inline-block;
}
#container li {
float: left;
height: 33px;
line-height: 30px;
}
Here is a great solution: http://css-tricks.com/centering-list-items-horizontally-slightly-trickier-than-you-might-think/
<div id="menu-outer">
<div class="table">
<ul id="horizontal-list">
<li><a href="#"><img src="images/list-item-1.gif" alt="list item 1" /></a></li>
<li><a href="#"><img src="images/list-item-2.gif" alt="list item 2" /></a></li>
<li><a href="#"><img src="images/list-item-3.gif" alt="list item 3" /></a></li>
<li><a href="#"><img src="images/list-item-4.gif" alt="list item 4" /></a></li>
</ul>
</div>
</div>
Now see the very simple CSS that makes it happen:
#menu-outer {
height: 84px;
background: url(images/bar-bg.jpg) repeat-x;
}
.table {
display: table; /* Allow the centering to work */
margin: 0 auto;
}
ul#horizontal-list {
min-width: 696px;
list-style: none;
padding-top: 20px;
}
ul#horizontal-list li {
display: inline;
}
It's the table div that get the job done. Some days I think "Whatever works." should be the slogan for CSS.
in css :
ul {
float: left;
}
jquery
centerize = function(){
var parentWidth = $("ul").parent("#container").width();
var width = $("ul").width();
var dif = (parentWidth - width) / 2;
$("ul").css("margin-left", dif + "px");
};
centerize();
probably u need to work for every browser zoom, so add :
$(window).resize(function(){
centerize();
});
