parent / siblings

**regicidedelferoz** · 03-12-2012, 03:44 AM

good day guys,

how can i do this with css? i want to design all elements which has a sibling?

ex.

Code:

<ul>
	<li><a href="#">element</a>
    	<ul>
        	<li><a href="#">element</a></li>
        </ul>
    </li>
    <li><a href="#">element</a></li>
</ul>

what i want to do is, if <a> within an <li> has a sibling (which is <ul>), i want to add style on it,.

thanks in advance
more power!

If I understand the question correctly you cannot, at least not that I know of.

Let's make sure I got the question right though:

You want to style an a tag based upon whether or not it has a sibling ul after it, right?

The closest I'm aware of is the adjacent selector. However, it only works if the element to be styled follows the sibling, not precedes it. So this works:

HTML Code:

<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<style type="text/css">
li ul + a {
	color: red;
}
</style>
</head>
<body>
<ul>
	<li>
    	<ul>
        	<li><a href="#">element</a></li>
        </ul>
	<a href="#">an a tag that's an adjacent following sibling of a ul, within an li - I'm Red!</a>
    </li>
    <li><a href="#">element</a></li>
</ul>
</body>
</html>

But there's nothing for the other way around.

A general rule of thumb in css selectors is that (in the DOM) they can look above the element to be styled and use that as a basis for selection, but not below.

its working sir,. thanks you,.

but its not working with my code:

Code:

#mj_menu {border:1px solid #000; padding:1em; width:200px; background:#fff;}
#mj_menu li {list-style:none;}
#mj_menu li a {display:block; height:30px; border-bottom:1px dotted #000; line-height:1.9em; text-indent:1em; text-decoration:none; text-transform:capitalize; color:#333;}
#mj_menu li a:hover, #mj_menu .active {color:#333; background:#ddd;}
#mj_menu li ul {position:absolute; margin-left:12em; margin-top:-2.1em; border:1px solid #000; padding:1em; width:200px; background:#fff;}
#mj_menu li ul + a {background:#00F !important;}
#mj_menu .displayNone {display:none;}

Code:

<ul id="mj_menu">
    <li><a href="#">menu 1</a>
        <ul class="displayNone">
            <li><a href="#">menu 1.1</a>
                <ul class="displayNone">
                    <li><a href="#">menu 1.1.1</a>
                        <ul class="displayNone">

The a tag must follow the ul tag. There's no 'look behind' in css.

I guess I wasn't clear. You cannot do this with css and your markup because it only works if the ul comes before the a.
