I'm wondering if there is a pure CSS way to add a class to elements of another class. The problem I'm trying to solve is below, which is also an example.
Using bootstrap, I have a number of elements that look like this:
<li class="nav-item">
<a class="nav-link" href="#">Law</a>
</li>
What I would like to do is add the pull-right class to each element with the class nav-item (I think), in order to make the nav items all float to the right.
Is there a pure CSS way to do this? I think the answer is no, at least without LESS/SASS/JS, but I'd love to be disabused of that notion.
No, if you are wanting to add a class to the CSS you would need to use either JavaScript or Jquery. I would recommend Jquery because IMO it is a little easier to work with when adding classes.
Or you could just add the class to each nav-item:
<li class="nav-item pull-right">

I have build a dropdown menu that works a sweet as it gets.
Right click on an element, brings up he dropdown menu, i hover over the first choise, soo far so good, the font color and the background color changes as it should and the sub-menue opens. The problem is that when i hover over the sub-menu, the i "loose" the gray background color of the "parent"
Any ideas ?
<div id="contextMenu" class="dropdown-menu" role="menu" style="display: block; left: 997px; top: 438px;">
<ul class="dropdown-menu side" role="menu" aria-labelledby="dropdownMenu" style="display:block;position:static;"><li class="dropdown-submenu"><i class="fa fa-paste" aria-hidden="true"></i> PARENT OPTION <ul class="dropdown-menu"> <li> <a tabindex="-1" data-url="/common/docitem/copymove/?document=247&dest=1&obj_table=companydocument&f=null" id="add_id_copy_p" style="cursor:pointer;" class="js-movecopy-docitem"> Siblin Option</a> </li>
First things first, you must include a code segment to make it easier to understand the issue, as #Paulie-d and #Rokibol Hasan mentioned. To be honest, this sounds like maybe you have conflicting CSS rules or lack of specificity, which results in your parent element being affected on :hover.
These would be the steps I would use to solve this:
Use the find function of your development IDE (CTRL + F) to find :hover elements. Avoid using very broad CSS selectors.
Make sure you have assigned the correct id and class attributes in the desired section of code.
Refresh your memory on CSS specificity. I provide you this website instead of Mozilla only because I do not know if you can handle it. If you are experienced, prefer this website.
Refresh your memory on CSS selectors.
At this point, go in your CSS and start commenting out and testing one by one sections of code that may affect the parent element you speak of.
Assume I have HTML code like this:
<ul class="my-list">
<li> One </li>
<li> Two </li>
<li> Three </li>
</ul>
If I wanted to style the <li> elements, I could use the following selector in CSS:
.my-list li {...}.
The .my-list class here ensures I won't change any <li> elements for other lists.
Is there any additional benefit or usefulness to adding the same class to each <li> element and simply using that as the selector instead, e.g:
<li class="my-list-item">
.my-list-item {...}
I don't think there is because at the end of the day, you are just selecting an element rather than a class or vice-versa.
Unless you are doing something to target specific elements in a list, then adding a class to the li's would be beneficial as then you can make all the .my-list-item red and the .my-list-item--blue blue for example
I could be completely wrong as there might be some more side effects that even I don't know as in it's quicker to select an element rather than a class but even if that is the case, you wouldn't notice anything.
Here is a tricky challenge for you guys, CSS selector to get the :last-child that doesn't have a class.
What I have tried so far:
.nav-item:not(.nav-item--mobile):last-child {...}
.nav-item:last-child:not(.nav-item--mobile) {...}
I have similar query selectors that do some fun stuff, so I'd rather try and do this via CSS. The mobile items can be variable in quantity.
// Get the first child in the list when there are n or more, and
// they are not mobile. Yes, this actually works.
.nav-item:first-child:nth-last-child(n+7):not(.nav-item--mobile)
The following will give me the last child in all cases, but I want the last child that isn't a mobile only child.
.navigation-item--top:last-child
Target
generic generic generic generic generic mobile mobile
^
target this one
HTML
<ul class="nav-items-list">
<li class="nav-item"></li>
<li class="nav-item"></li>
<li class="nav-item"></li>
<li class="nav-item"></li>
<li class="nav-item nav-item--mobile"></li>
<li class="nav-item nav-item--mobile"></li>
</ul>
Yes I could figure out which is the correct one in the generated navigation, or I could find it with JS.
Unfortunately what you want cannot be achieved using CSS only.
:last-child asks only one question, no matter what else you specify: Am I the last child of my parent element?
Sadly, there is no :last-of-class, only :last-of-type, but this cares only about element type.
It is not even planned for selectors level 4 that you can specifiy a class or other limiting property.

I am creating a dynamic navigation list and I want to be able to highlight the page from that list that the user is currently browsing without having to explicitly add the style into a CSS document. For instance,
<div class="check-me">
<ul class="any-class">
<li class="hats">Hats</li>
<li class="shirts">Shirts</li>
<li class="pants">Pants</li>
</ul>
</div>
Essentially, I want to be able to replace the "any-class" with another class, one that appears on an LI element within the "any-class" UL.
<div class="check-me">
<ul class="shirts">
<li class="hats">Hats</li>
<li class="shirts">Shirts</li>
<li class="pants">Pants</li>
</ul>
</div>
I cannot append an "active" class to any LI due to limitations, so I wonder if this is possible using a wildcard CSS selector to use inside div.check-me to highlight anything that shares the same class with the UL. I hope I've been clear enough.
So I'm using menu_attributes (http://drupal.org/project/menu_attributes) to add specific classes to my menu items.
A problem for me is that these are added to the link itself
<li class="leaf active menu-mlid-873><a class="customClass active" href="/">Home</a></li>
But I would like to somehow make it like this, so that the class is also used for the parent of the link
<li class="customClass leaf active menu-mlid-873><a class="customClass active" href="/">Home</a></li>
I tried using theme_menu_alter but can't seem to figure out how I can get the class from there too.
