Pseudo-class nesting / SCSS Linter Warning - css

I'm relatively new to SCSS and try to improve my skills using a linter. I have this little example, where I want to display a submenu only if the parent menu-item is hovered. While this code is working, the linter gives me a "Class should be nested within its parent Pseudo-class".
.menu-item {
.submenu {
display: none;
}
&:hover .submenu {
display: block;
}
}
<ul>
<li class='menu-item'>
<a href=''>
Menu 1
</a>
<ul class='submenu'>
<li>Submenu 1.1</li>
<li>Submenu 1.2</li>
</ul>
</li>
</ul>
I have no idea how the :hover part could be nested into the .submenu part. Can you help?


I found the solution and it was so simple, I just had to nest the .submenu into the hover part :(
.menu-item {
.submenu {
display: none;
}
&:hover {
.submenu {
display: block;
}
}
}
<ul>
<li class='menu-item'>
<a href=''>
Menu 1
</a>
<ul class='submenu'>
<li>Submenu 1.1</li>
<li>Submenu 1.2</li>
</ul>
</li>
</ul>


Your SASS code will compiled to the below CSS code which is working fine. Just make sure that your SASS code is properly compiling to CSS.
.menu-item .submenu {
display: none;
}
.menu-item:hover .submenu {
display: block;
}
<ul>
<li class='menu-item'>
<a href=''>
Menu 1
</a>
<ul class='submenu'>
<li>Submenu 1.1</li>
<li>Submenu 1.2</li>
</ul>
</li>
</ul>

css ul li nested menu with a padding. How on hoover retain width of the menu?

Example here http://jsfiddle.net/v8yhk7Lr/
html
<div class="navig_div" id="mainnavig_div" >
<ul class="mnav-ul">
<li class="mnav-ul-li">Option One
<ul class="mnav-ul-ul">
<li>Option One 1 </li>
<li>Option One 1 longer </li>
</ul>
</li>
<li class="mnav-ul-li">Option Two long text
<ul class="mnav-ul-ul">
<li>Option Two 1 </li>
<li>Option Two 1 longer </li>
</ul>
</li>
<li class="mnav-ul-li">Option Three
<ul class="mnav-ul-ul">
<li>Option Three 1 </li>
<li>Option Three 1 longer </li>
</ul>
</li>
</ul>
</div>
css
.mnav-ul-li { float: left; display: block; }
.mnav-ul-li a { display:inline-block; padding:10px 25px; }
.mnav-ul-ul { display: none; }
.mnav-ul-li:hover > ul { display: block; }
Mouse over on Option One, see nested menu. But Option Two long text and Option Three moves to right. I want Option Two long text and Option Three remain at the same place (or Option One have the same width that was before mouse over).
Can set width like .mnav-ul-li { float: left; display: block; width:150px; } (example here http://jsfiddle.net/v8yhk7Lr/1/) but in such case the longer text is in 2 lines and one item may be short text, another long text, so space between navigation items would be different. With padding space would be the same between all items).
How to retain width on hover (on hover keep the same width that was before hover)?

.mnav-ul-li:hover > ul - add position: absolute;
.mnav-ul-li { float: left; display: block; position: relative; }
.mnav-ul-li a { display:inline-block; padding:10px 25px; }
.mnav-ul-ul { display: none; }
.mnav-ul-li:hover > ul { display: block; position: absolute; top: 30px; left: 0; }
<div class="navig_div" id="mainnavig_div" >
<ul class="mnav-ul">
<li class="mnav-ul-li">Option One
<ul class="mnav-ul-ul">
<li>Option One 1 </li>
<li>Option One 1 longer </li>
</ul>
</li>
<li class="mnav-ul-li">Option Two long text
<ul class="mnav-ul-ul">
<li>Option Two 1 </li>
<li>Option Two 1 longer </li>
</ul>
</li>
<li class="mnav-ul-li">Option Three
<ul class="mnav-ul-ul">
<li>Option Three 1 </li>
<li>Option Three 1 longer </li>
</ul>
</li>
</ul>
</div>

Simply add position absolute to the ul
.mnav-ul-li:hover > ul {
display: block;
position:absolute;
}

Styling nested lists with any depth

I was wondering if it's possible to style nested unordered lists with CSS only, without using any scripts. The problem is that CSS needs to work for any depth of the list tree.
For example, I have a list:
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li class="holder">
<ul>
<li>Item 4</li>
<li>Item 5</li>
<li class="holder">
<ul>
<li>Item 6</li>
<li>Item 7</li>
<li>Item 8</li>
<li class="holder">
<ul>
<li>Item 9</li>
<li>Item 10</li>
<li>Item 11</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
And this is my CSS:
li{
background: gray;
border: 1px solid;
display: block;
margin: 2px;
}
.holder{
background: none;
border: none;
}
/*replace these styles*/
li > ul > li{
background: white;
}
li > ul > li > ul > li{
background: gray;
}
li > ul > li > ul > li > ul > li{
background: white;
}
If node's parent has background A, node should have background B. If node's parent has background B, node should have background A.
Please check : http://jsfiddle.net/bCU34/6/

CSS selectors allow you to select all named elements of a parent node by separating the named element from the parent element with a space. To select all unordered list elements, for example, you would do like below. Notice all ul elements at any depth inherit the style no bullets/margin/padding. In order do style nth layer for an element type, you need to use the parent selector >. See below. I used font color but you could set background images the same way. Note there is no decendant level selector at this time that I know of. This was addressed on another post CSS select nested elements up to N levels deep.
.container ul {
list-style-type: none;
margin: 0;
padding: 0;
}
.container > ul > li {
color: green;
}
.container > ul > li > ul > li {
color: red;
}
.container > ul > li > ul > li > ul > li {
color: blue;
}

There isn’t any specific way of doing this currently with Selectors level 3, and the current draft of Selectors level 4 doesn’t seem to add anything either. I had a dig through the www-style mailing list and came up with this post by Lachlan Hunt from April 2005 that suggests that an :nth-descendant() style selector had been considered but never specified.

third level of CSS dropdown menu not appearing in two-column format

I have constructed a three-level dropdown using CSS. It works until I add this to the CSS:
columns: 2;
-webkit-columns: 2;
-moz-columns: 2;
The HTML is basically just two unordered lists (by the way, the "feelings" list and the "needs" list have the same content -- that will change eventually -- this is just for experimenting!):

If I eliminate the first CSS item (setting the menu to two columns), the last level of the menu appears (the items in small letters as opposed to all caps). With the two-column CSS in place, the third level doesn't appear.
Here is a fiddle:
http://jsfiddle.net/Lq7NK/2/
Interestingly, on the fiddle, the third level does seem to be trying to appear a bit, but it's certainly not working the way I'd like it to, which is the third level appearing in a vertical column to the right of the second level item.
Any thoughts will be appreciated!
/* image below was added after original question, in response to a request for a picture */
The top screenshot in this picture shows what comes up now when I hover over the first feeling, AFRAID -- and it is actually pretty much what I want (though obviously it needs some prettifying): two sets of two-column dropdowns, namely, the one in all caps and the one in all small letters. (This is basically with the code shown above, but with one change, namely, removing ul ul to leave only ul ul ul as suggested by user3369554.) However, when I move the cursor, stuff starts jumping all over the place; the screenshot on the bottom shows one state, but things just jump all over in a very disconcerting way. For instance, I would like to be able to just move the cursor over to where ANGRY is at the top of the second column. But if I try to do that, it jumps to somewhere else. And if I go to that place, it jumps to still another location. If the both sets of emotions (all caps and all small letters) would hold still in the configuration shown at the top, and let me click on them, I'd be happy.

I don't know if I'm understanding well, but you can get the third level in a 2 column format to the right of the second level, if you replace:
ul ul, ul ul ul
for
ul ul ul

Creating simple CSS multilevel menu

I am trying to make a webpage with a navigation functionality EXACTLY like this one: http://www.rex-ny.com/ where you click a list item and its children items appear and stay.
I can do it with hover, but I can't figure out how to make it stay when not hovering.
It seems like the most simple thing is the most difficult to do.
<ul id="menu">
<li>Menu 1
<ul>
<li>Item A</li>
<li>Item B</li>
<li>Item C</li>
</ul>
</li>
<li>Menu 2
<ul>
<li>Item A</li>
<li>Item B</li>
<li>Item C</li>
</ul>
</li>
<li>Menu 3
<ul>
<li>Item A</li>
<li>Item B</li>
<li>Item C</li>
</ul>
</li>
</ul>
Thanks
Here is a jsfiddle http://jsfiddle.net/phzuC/

Here is a CSS only solution as the OP requested, using tabindex
DEMO http://jsfiddle.net/kevinPHPkevin/phzuC/2/
#menu li > ul {
display:none;
}
#menu li:focus > ul {
display:block;
}
li {
outline: 0;
}
EDITED
Here is a jQuery solution should you ever need it. It keeps the submenus open and it's simple to implement. 11 lines of code.
DEMO http://jsfiddle.net/kevinPHPkevin/phzuC/5/
$(document).ready(function() {
$(".nav-top > li").click(function(e) {
if($(this).find('ul').hasClass('expanded')) {
$(this).find('ul').removeClass('expanded').hide();
} else {
$(this).find('ul').addClass('expanded').show();
}
});
$('.nav-top a').click(function(e){
e.preventDefault();
});
});

Here is another CSS only solution that uses either:
Checkboxes if you want the menus to toggle on click
radio buttons if you want the menus to auto close when another is selected
Reference:
CSSTricks: Stuff you can do with the “Checkbox Hack”
The CSS Ninja: CSS Tree
Demo
Basic behavior CSS (the demo has more styling to remove the default list indentation/bullets):
.sideMenu input[type='radio'],
.sideMenu input[type='checkbox'] {
display: none;
}
.sideMenu input[type='radio'] + ul,
.sideMenu input[type='checkbox'] + ul {
position: relative;
display: none;
}
.sideMenu input[type='radio']:checked + ul,
.sideMenu input[type='checkbox']:checked + ul {
display: block;
}
HTML (can be arbitrarily deep):
<nav class="sideMenu">
<ul>
<li>
<label for="menu1">Menu 1</label>
<input id="menu1" type="checkbox" name="menu1">
<ul>

CSS dropdown menu: position of subitems

I try to create a dropdown menu with CSS for a Wordpress template. When I hover a menuitem (e.g. "Cupcake Ipsum" like you can see on the picture), the whole menu is displayed in a weird way.
I hope the picture is self-explanatory enough. The menuitem "Cupcake Ipsum" is hovered on the bottom view of the menu:

<div id="menu" role="navigation">
<div class="menu">
<ul>
<li class="current_page_item">
<a title="Home" href="http://whatever.com/wordpress/">Home</a>
</li>
<li class="page_item page-item-40">
Cupcake Ipsum
<ul class="children">
<li class="page_item page-item-388">
Red Velvet Cupcake
</li>
<li class="page_item page-item-390">
Mango Cupcake
</li>
<li class="page_item page-item-392">
Chocolate Cupcake
</li>
</ul>
</li>
<li class="page_item page-item-43">
Bacon Ipsum
<ul class="children">
<li class="page_item page-item-405">
</ul>
</li>
<li class="page_item page-item-45">
Veggie Ipsum
<ul class="children">
<li class="page_item page-item-397">
Tomato
</li>
<li class="page_item page-item-399">
Lettuce
</li>
<li class="page_item page-item-401">
Broccoli
</li>
<li class="page_item page-item-403">
Onion
</li>
</ul>
</li>
</ul>
</div>
</div>
My CSS code is:
#menu ul li a {
text-decoration: none;
color: #CCCCCC;
font-size: 16px;
padding: 10px;
display: block;
position:relative;
}
#menu ul li a:hover {
background-color: #006699;
color: #FFFFFF;
}
#menu ul li ul li a {
clear: left;
line-break: strict;
background-color: #006699;
padding: 5px;
font-size: 10px;
}
#menu ul li ul li {
display: block;
float: none;
clear: left;
}
.menu ul li {
display: inline-block;
position: relative;
}
.menu li ul {
position: absolute;
}
.menu li:not(:hover) ul {
display: none;
}
I want to create a dropdown menu where one subitem is below the other. Tried a lot but I cannot manage to arrange the subitems correcly.

What did you omit? Your exact code in this fiddle works, check your css, you have something overriding some of your rules, check each element, see when the rules you pasted here are overwritten.

Can you put your code in a jsfiddle? Until then, I can tell you that one of your sub elements of the main <li> is display: block; and pushing the other top level <li>'s out of placement.
