css last-child matches all children - css

I am trying to use create a separator between my links by creating a border on the right side of each of them. Then on the last one, remove it. I have the following html and css but what I'm finding is that each "a" tag matches the last-child selector. I'm not clear why and what the proper way would be to do this.
<ul class="nav">
<li>link1</li>
<li>link2</li>
<li>link3</li>
<li>link4</li>
</ul>
.nav a { border-right:solid 1px #000;}
.nav a:last-child { border-right-width:0px;}

That's because each a is the last-child of its parent li. You'd want something like .nav li:last-child a instead.

All your <a> tags are last children of their parent <li>

hover on parent element with css

I was wondering if there is a way you can apply a hover effect on parent element with just css.
For example, I have a navigation:
<nav>
<ul>
<li id="firstLiElement" class="main-nav ieraksti">ieraksti!</li>
<ul id="audio_sub_menu">
<li class="mes">mēs 1</li>
<li id="klienti">mēs 2</li>
</ul>
<li class="main-nav" id="audio">paklausies!</li>
<li class="main-nav" id="video">paskaties!</li>
<li class="main-nav" id="kontakti">pasūti!</li>
</ul>
</nav>`
And what I want is to, when hovered on
nav ul ul li
element, it affects the
#firstLiElement
.
I know it can be done with JS, but there has to be also a way to do this with css. I found a lot of solutions when you need to affect the sibling or child, but didn't find anything for this situation.
EDIT:
Sorry, didn't even write what I was looking for... Yes, sub_menus are hidden, but when I hover the main navigation li element, they shove up, and they stay visible also when I hover on them. What I am missing is to change the background color of the main navigation li element when the sub menu is hovered.
I found this for you.
a < img { border: none; }
In this example, it would select a tags but only if they contained an img tag. (Aside: this would be a weird departure from the typical syntax where the actual elements being selected are on the right, this would be on the left).
a img:parent { background: none; }
The key difference being that the :parent syntax would only evaluate a single element, the parentNode available in the DOM for every element. This would be similar to forcing the :has selector to only evaluate children rather than all descendants.
https://css-tricks.com/parent-selectors-in-css/
I believe it can't be done. CSS or Cascade Style Sheet - keyword here is Cascade - executes in a cascade direction and not the other way around.
You can do this (assuming the audio_sub_menu, i.e., is hidden):
nav ul a:hover ul {
visibility: visible;
}
And you'll be targeting a child on its parent hover. So, you can either change your layout and design to use this knowledge, or go with the JS solution :)
edit
to get the same color, style the :hover on the parent as well and change the first </a> in your HTML code
<nav>
<ul>
<a href="#"><li id="firstLiElement" class="main-nav ieraksti">ieraksti!</li>
<ul id="audio_sub_menu">
<li class="mes">mēs 1</li>
<li id="klienti">mēs 2</li>
</ul>
</a>
<li class="main-nav" id="audio">paklausies!</li>
<li class="main-nav" id="video">paskaties!</li>
<li class="main-nav" id="kontakti">pasūti!</li>
</ul>
</nav>
And the CSS
nav ul a:hover {
background-color: your_color;
}
nav ul a:hover ul {
visibility: visible;
background-color: your_color;
}
edit - On the hetasbo's answer
those are suggested css selectors, they don't exist

Good practice on selecting a list menu

Considering this markup:
<div id="container">
<div id="mainmenu">
<ul>
<li> <h1>My Dashboard</h1></li><br>
<li> <h1>About</h1></li><br>
<li> <h1>Contact</h1></li><br>
<li> <h1>Setttings</h1></li><br>
<li> <h1>Log Out</h1></li><br>
</ul>
</div>
</div>
Selecting this way is a valid thing? I am having issues with some properties.
#container ul li{
display: inline-block;
}
#mainmenu ul li a{}
#mainmenu ul li a:hover{}
full sample:
https://jsfiddle.net/jhr1q1q4/
I'm somewhat unsure what you're asking...
Strictly speaking, the selectors you provided are valid and would select the <a> elements within your #mainmenu element.
But I would ask: is the ul li part of the selectors necessary? You could rewrite both of them as
#mainmenu a {}
#mainmenu a:hover {}
and they would work the same and require less parsing. If you wanted to only select <a> elements that are descendants of <li> elements, you could keep the li in your selector; however, the ul is not necessary -- it is implied your <li> elements will be children of a <ul> (assuming you're writing valid HTML).
Another note: <a> elements are inline, meaning they're meant to act at the text level. <h1> elements, on the other hand, are block-level elements, and thus do not belong inside <a> elements. In fact, you usually shouldn't have more than one <h1> on a page, let alone be using <h1>'s to mark up menu items. If you want your menu items to be big like headers, use your CSS rules to style them that way.
I am having issues with some properties.
What properties are causing trouble?

Styling a dynamic nested UL structure

I have a nested UL structure that represents a folder tree which can grow very deep. I'm stuck at doing a simple :hover effect for the LI elements. The problem is that doing a li:hover won't work as it affects all the parent "li's" aswell. Usually I would have tried to apply the hover effect to a link element or something in the LI, to avoid parents taking the style aswell, but due to circumstances that's not an option now. I have a working solution by using javascript to place a class on the hovered LI and then style this class instead, but i'm really interested in seeing if there's actually a way of accomplishing this through pure css.
I imagine there may be a way of doing a very "hardcoded" css solution but i am more interested in a dynamic and clean one, since the structure can nest indefinitely.
Maybe there's some pseudo selector i'm not aware of? Note that it doesn't have to be IE<8 compatible
<ul>
<li>
This LI should not recieve the hover effect
<ul>
<li>
A li:hover will place the effect on this LI,
but also the parent LI, since that element is
also techincally being hovered.
</li>
</ul>
</li>
</ul>
If you want to use pure CSS then you will need to us parent, child, elements.
For the hover elements:
ul li:hover{
"Style"
}
For the other elements:
ul li ul li{
"Style"
}
UPDATE: I just reread your question, in which you state:
"Usually I would have tried to apply the hover effect to a link
element or something in the LI, to avoid parents taking the style as
well, but due to circumstances that's not an option now."
If that is true, then the solution below is not viable for your circumstance, and you cannot achieve what you desire with pure CSS. I've left my answer, however, as others who want to achieve this but can use a nested element may find it useful.
Pure CSS Only by Adding HTML
The only way you can possibly achieve something of what you seek by pure CSS is to add an extra element (like a span) within the li and perform the hover on that. I assume that whatever folder is being hovered, that folder alone is what you want to highlight. If so, this fiddle illustrates what I am saying, using this code:
HTML
<ul>
<li>
<span>Folder 1</span>
<ul>
<li>
<span>Folder 1.1</span>
<ul>
<li>
<span>Folder 1.1.1</span>
<ul>
<li>
<span>Folder 1.1.1.1</span>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
CSS
li span:hover {
color: red;
background-color: yellow;
}
Now, if you want child folders to also highlight on hover of a parent folder, then perhaps this fiddle illustrates what you want with this code change:
CSS
li span:hover,
li span:hover + ul span {
color: red;
background-color: yellow;
}
They key point is to utilize the extra element to control the hover, whether of the item itself or any later generation elements that the hover should affect.
Not clear at all... but if you want to style nested LI when you are hovered the parent LI without styling the parent one...
Try this:
CSS
ul li ul li {
color: blue
}
ul li:hover ul li {
color: red
}

Your question is not very clear and also it will confuse. Let me explain, when the user hover the city (India / China / UK), style should be applied to State and Country through CSS.
<ul>
<li>India (Apply Style)
<ul>
<li>India State (Apply Style)
<ul>
<li>India City (On Hover)</li>
</ul>
</li>
</ul>
</li>
<li>China
<ul>
<li>China State
<ul>
<li>China City</li>
</ul>
</li>
</ul>
</li>
<li>United Kingdom
<ul>
<li>UK State
<ul>
<li>UK City</li>
</ul>
</li>
</ul>
</li>
</ul>

:first-child targeting all child elements

I have a unordered list with id of "navigation" and a few child list-item elements.
I am trying to select just the first item with :first-child but it is applying the CSS I use with this to all other list items.
ul#navigation li:first-child{
background:#fff;
}
So, to reiterate: this is giving every list-item a white background. I just want to select the first element. What is going wrong?
According to the comments, your problem is that your markup looks like this:
<ul id="navigation">
<a href="http://google.com">
<li>Google</li>
</a>
</ul>
Note how every li will be a :first-child under this model. I would suggest you go with the more appropriate structure of nesting your anchor within your list item. If you want the anchor to fill up the list item, set its display to block:
<ul id="navigation">
<li>Google</li>
</ul>
With the accompanying CSS:
#navigation a { display: block }
Once you have those structural changes in place, your selector should target the first list item:
/* > to target only immediate list items */
#navigation > li:first-child {
background: red;
}

Can i apply a style to a parent element [duplicate]

This question already has answers here:
Closed 11 years ago.
Possible Duplicates:
Style parent li on child li:hover.
Is there a CSS parent selector?
I have a nave menu.
On li a:hover the #drop-down-menu appears.
Can I apply a style to the li a while hovering over the drop down menu?
Can you apply a style to the parent element while hovering over the child element?
i.e. I want a border-bottom:2px solid #ffffff; to appear under the li a, while i am hovering over the #drop-down-menu.
Can't figure it out.
If your anchor is - or can be - fullsize (i.e. the size of the list item), then you can use:
li:hover
You would need to use javascript for this. CSS doesn't allow any way to select a parent element.
No. CSS doesn't work that way. You can only go down.
However, if you have your HTML structured properly, you can achieve the effect you're going for.
Assuming the following HTML:
<ul id="main">
<li>A dropdown
<ul class="dropdown">
<li>A submenu</li>
</ul>
</li>
</ul>
You can have the following CSS, and it should work:
#main li:hover a {
border-bottom: 1px solid black;
}
Here's a (very) rough Fiddle.
