Absolute positioned ::before element ignores z-index stacking - css

I am creating a very simple navbar and I want hover transitions on the links. I would like to add ::before elements in each link to smoothly transition a different color background on hover. The problem is (as far as I am concerned) that those ::before elements ignore their z-index staking and they hide the link text behind.
I would link to know if I am trying to do something impossible or there is actually a solution I am unable to find.
ul.menu-principal>li {
display: inline-block;
}
ul.menu-principal>li>a {
color: #000;
display: block;
text-transform: uppercase;
padding: 10px;
position: relative;
z-index: 96;
}
ul.menu-principal>li>a::before {
content: '';
position: absolute;
z-index: 95;
top: 0;
left: 0;
width: 100%;
height: 0;
background: orange;
transition: all .2s linear;
}
ul.menu-principal>li>a:hover::before {
height: 100%;
}
ul.menu-principal>li:hover a {
color: #fff;
}
<ul class="menu-principal">
<li>Item-01</li>
<li>Item-01</li>
<li>Item-01</li>
<li>Item-01</li>
</ul>

Thank you all for the responses.

You can just use for your case z-index: -1:
ul.menu-principal>li {
display: inline-block;
}
ul.menu-principal>li>a {
color: #000;
display: block;
text-transform: uppercase;
padding: 10px;
position: relative;
z-index: 96;
}
ul.menu-principal>li>a::before {
content: '';
position: absolute;
z-index: -1;
top: 0;
left: 0;
width: 100%;
height: 0;
background: orange;
transition: all .2s linear;
}
ul.menu-principal>li>a:hover::before {
height: 100%;
}
ul.menu-principal>li:hover a {
color: #fff;
}
<ul class="menu-principal">
<li>Item-01</li>
<li>Item-01</li>
<li>Item-01</li>
<li>Item-01</li>
</ul>

animating :after pseudo element does not work

I am new to coding, I have tried various solutions from similar questions asked, but nothing seems to work.
I have the following problem:
I made a breadcrumb, including various divs with :before and :after elements - shaping them like connected arrows.
The problem is, I made an animation for the breadcrumb element to fade-in-down. However, no matter in what combination I tried -> The :after element does not animate properly, or at all.
It kinda just pops up after :before and the parent div .breadcrumb have finished sliding in. Can anybody help me here, or has anyone maybe have aa clue?
... I have tried animating the :after element separatly, with transition, with animation-delay etc...nothing seems to work...everything slides in fine from top, excep the :after element, which just pops up ugly after the animation from my ".breadcrumb" is finished.

Without seeing your HTML code I just had to take a guess at how you need this but here is an example with the after pseudo element coming in from the top and sitting on top of the before pseudo. Hope this helps you get what you are looking for. You can have it come in from any direction that you want.
ul {
list-style: none;
display: flex;
overflow: hidden;
}
li {
margin-left: 20px;
margin-right: 20px;
position: relative;
}
li::before {
content: '';
width: 20px;
height: 20px;
background-color: green;
position: absolute;
right: -25px;
}
li::after {
content: '';
width: 20px;
height: 20px;
background-color: red;
position: absolute;
right: -25px;
top: -100px;
transition: all 1s;
}
li:hover:after {
top: 0;
}

Getting SVG plus symbol to appear to the right of tab, not the right of the containing div

So I've got a problem where I've got two tabs (https://codepen.io/databell/pen/LYjxvyx) where the first tab opens up content and the second opens up a modal.
Now to be clear, those functions work. That's not the issue. So for those purposes, I deleted those out of my example. Focusing on CSS here.
My problem is I want plus + symbols to appear to the right side of each tab (really a div) and instead one tab has the symbol to the far right of the container, even though the tab is set to width 100%. So I'm stumped as to what the problem is.
This is meant to go into a Shopify store using the Dawn theme, so I'm using their elements here to create this interface.
Here's the code.
<div id="info-additions" class="product__accordion accordion info-additions-content" >
<details>
<summary>
<div class="summary__title info-additions-tab g-flex">
<h2 class="h4 accordion__title t-body benefits">

<span></span>
</h2>
</div>
<div class="summary__title info-additions-tab g-flex">

if you want an absolute element like + to stay in the parent element you have to set the position of the parent to "relative".
you have two problems. summary__title doesn't have a position so + doesn't stay in it .
for the second tab, your modal button has a relative position that makes the + stay inside of it instead of the summary__title.
.accordion .summary__title {
...
position: relative; // add position
}
#info-additions button {
...
position: unset; // unset the position of the button
}

How to hover parent & have child respond to keyframe animation

I am trying to write code that mimics this animation as much as possible.
I have been going over keyframe animations & I think that they can be used to do what I need them to do.
I effectively want to have three things happen when the user hovers over the parent element. The first is the color
on the right side of the element will change dynamically (as in the picture & as in the example code), the
icon will animate into the picture & then the text will then animate.
I am new to programming & I am looking for some direction.

After/Before pseudo elements in < IE11

I created a pseudo element which transitions width to reveal a second pseudo element below of a different colour. It's working in all browsers except IE where the pseudo element becomes 100% of the page width when hovering off the element. What gives?
<span>Hello world</span>
<style>
span{
position: relative;
font-size: 64px;
}
span:before, span:after{
position: absolute;
content: "";
left: 0;
bottom: -3px;
width: 100%;
height: 5px;
transition: all 1s ease;
}
span:before{
background: green;
}
span:after{
background: red;
}
span:hover:after{
width: 0;
}
</style>
https://jsfiddle.net/mmbgLf51/
Can't say (yet) why that happens but here is a workaround, where I use the right property instead.
Update
Giving the span inline-block (or block) does as well solve it, which would mean that the inline element for some reason gets pushed by the pseudo content, and most likely qualifies as a bug ..
.. or normal IE behavior :)
Sample 1 (using right)
span{
position: relative;
font-size: 64px;
}
span:before, span:after{
position: absolute;
content: " ";
left: 0;
bottom: -3px;
right: 0;
height: 5px;
transition: all 1s ease;
}
span:before{
background: green;
}
span:after{
background: red;
}
span:hover:after{
right: 100%;
}
<span>Hello world</span>
Sample 2 (using display: inline-block)
span{
display: inline-block;
position: relative;
font-size: 64px;
}
span:before, span:after{
position: absolute;
content: "";
left: 0;
bottom: -3px;
width: 100%;
height: 5px;
transition: all 1s ease;
}
span:before{
background: green;
}
span:after{
background: red;
}
span:hover:after{
width: 0;
}
<span>Hello world</span>
