as seen in my codepen, there are two greyscaled shapes. Now its only possible to hover one of both, because the original size is a box and overlaps both images.
But is there a way to like recognize the shape when hovering it? Z-index does not lead to a result...
Hope you can help me out a bit!
would be great without JS but its not a k.o.

For that simple shape, You may play with pointer-events to remove it and a pseudo element rotated to switch it back on only on one part of the image.
about pointer-events https://css-tricks.com/almanac/properties/p/pointer-events/
example
/* CSS switch of pointer-events on/off */
#two {
position: relative;
overflow: hidden;/* hide pseudo overflowing */
pointer-events: none;
}
#two:before {
pointer-events: auto;
content: '';
position: absolute;
top: 100%;
left: 0;
z-index: 2;
width: 150%;
height: 100%;
/* set transform according to ratio image */
transform-origin: top left;
transform: rotate(-30deg);
/* if you want to see where it stands , add borders or background */
}
/* end CSS switch */
img {
width: 700px;
height: 400px;
object-fit: cover;
display: block;/* avoids gap underneath */
}
#one img {
-webkit-clip-path: polygon(0 0, 0% 100%, 100% 0);
clip-path: polygon(0 0, 0% 100%, 100% 0);

Here is another idea to create the same using less of code and without clip-path
.container {
width: 300px;
height: 200px;
position: relative;
overflow: hidden;
}
.container img {
width: 100%;
height: 100%;
object-fit: cover;
display: block;
}
.container div {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
transform: skewX(-56.3deg); /* tan(angle) = Width/height --> angle = arctan(width/height) */
transform-origin: top;
overflow: hidden;
}
.container div img {
transform: skewX(56.3deg);
transform-origin: top;
}
.container img:hover{
filter:grayscale(100%);
}
<div class="container">
<img src="https://picsum.photos/800/600?image=1069">

I am currently making an animation that will apply a gradient mask on an image. The mask is a transparent mask and it will transform from right to left of the image. Here is my code.
<!DOCTYPE html>
<html>
<head>
<style>
.container {
height: 100vh;
width: 100vw;
background-color: white;
position: relative;
}
.first {
background-image: url('https://i.ibb.co/17zzm7P/flower.jpg');
background-size:cover;
position: absolute;
height: 100%;
width: 100%;
-webkit-mask-image: linear-gradient(to left, transparent 0px, black 20rem, black);
-webkit-animation: rightToLeft 5s forwards;
}
#keyframes rightToLeft {
0% {
-webkit-mask-position: 100vw 0%;
mask-position: 100vw 0%;
}
100% {
-webkit-mask-position: 0vw 0vw;
mask-position: 0vw 0vw;
}
}
</style>
</head>
<body>
<div class="container">
<div id="first" class="first"> </div>
</div>
</body>
</html>
Basically, the animation works well. However, the mask image is only applied to a specific area when it moves from right to left. Because the mask is transparent, I expect when it moves to the new area, the previous area it passed through is also transparent. How can I do to make the previous area transparent too?
Thank you so much for your time.
You are almost good, you only need to disable the repetition by using mask-repeat: no-repeat

I'm trying to do some page transitions for a project I'm working on, I have an animated overlay that comes onto the screen when the user is navigating the site using Barba but I'm having an issue.
I want a logo centered on the page that rolls in with the overlay but I need it to be positioned separately from the overlay since any transform on the overlay would affect the logo as well. (I want the logo to mask with the overlay element)
What I've tried :
Switching around the Element hierarchy/Z-index (I'm sure the problem lies somewhere in here)
Trying different transforms
Messing with Max Width (Had some success but I need the transform origin property)
Example -
let transitionOpen = false;
$('.transition-cta').on("click", function() {
if (transitionOpen === false) {
$('.transition-background').css("transform", "scaleX(1)");
$(this).css("color", "white");
transitionOpen = true;
} else {
$('.transition-background').css("transform", "scaleX(0)");
$(this).css("color", "black");
transitionOpen = false;
}
});
body {
background-color: lightblue;
}
.someContent {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
.transition-wrapper {
overflow: hidden;
}
.transition-background {
width: 100%;
height: 100vh;
position: absolute;
top: 0;
left: 0;
transform-origin: left;
transition: 0.7s ease-in-out;
background-color: #1f1f1f;
transform: scaleX(0);
z-index: 2;
}
.transition-center {
background-image: url('https://i.imgur.com/6um9G9h.png');
z-index: 2;
width: 150px;
height: 150px;
position: absolute;
background-repeat: no-repeat;
background-size: cover;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
.transition-cta {
text-decoration: underline;
cursor: pointer;
z-index: 3;
position: absolute;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
<div class="transition-wrapper">
<div class="transition-background"></div>
<!-- I want to clip this with the transition background -->
<div title="I only want this to show with the transition overlay" class="transition-center"></div>
</div>
<div class="transition-cta">Trigger Transition</div>
<div class="someContent">
<h1>Some Content</h1>
</div>
(The globe should roll in with the overlay)
This feels like an extremely simple problem but I'm really struggling to solve it. I can't tell if I'm burned out or this is actually as complicated as my brain is making it.
Thanks!
Use a clip-path animation instead and you can simplify your code by having the logo as background of the transition-wrapper
let transitionOpen = false;
$('.transition-cta').on("click", function() {
$('.transition-wrapper').toggleClass('show');
if (transitionOpen === false) {
$(this).css("color", "white");
transitionOpen = true;
} else {
$(this).css("color", "black");
transitionOpen = false;
}
});
body {
background-color: lightblue;
}
.someContent {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
.transition-wrapper {
width: 100%;
height: 100vh;
position: absolute;
top: 0;
left: 0;
transition: 0.7s ease-in-out;
background: url('https://i.imgur.com/6um9G9h.png') center/150px 150px no-repeat;
background-color: #1f1f1f;
clip-path: polygon(0 0, 0% 0, 0% 100%, 0 100%);
z-index: 3;
}
.transition-wrapper.show {
clip-path: polygon(0 0, 100% 0, 100% 100%, 0 100%);
}
.transition-cta {
text-decoration: underline;
cursor: pointer;
z-index: 3;
position: absolute;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
<div class="transition-wrapper">
</div>
<div class="transition-cta">Trigger Transition</div>
<div class="someContent">
<h1>Some Content</h1>
</div>
I would do something like:
$('.transition-cta').on("click", function() {
$('.transition-wrapper').toggleClass('opened');
$('.transition-content').animate({ width: 'toggle' }, 800);
});
body {
background: lightblue;
}
.content {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
.transition-content {
background-color: #1f1f1f;
display: none;
overflow: hidden;
position: absolute;
right: 0;
left: 0;
top: 0;
bottom: 0;
width: 100%;
}
.transition-cta {
position: relative;
text-decoration: underline;
z-index: 999;
}
.transition-wrapper.opened .transition-cta {
color: #fff;
}
.transition-content__inner {
width: 100vw;
}
.transition-content__inner img {
width: 150px;
height: 150px;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="transition-wrapper">
<div class="transition-cta">Trigger Transition</div>
<div class="content">
<h1>Some Content</h1>
</div>
<div class="transition-content">
<div class="transition-content__inner">
<img src="https://i.imgur.com/6um9G9h.png"/>
</div>
</div>

I want to create a calendar like set of 12 images that appear to flip up when clicked. I know about turn.js but I don't know enough javascript to start from scratch. I do have a programming background and am willing to learn but don't know where to start.
http://pageflip-books.com/index.php#ppp/page/1
is something like what I'm looking for but I want to show the top pages not the bottom ones.
Most of the examples I have found are for books/magazines with two pages side by side.
Thanks for any pointers.
I would look into CSS animations if I were you. An example can be found here: https://codepen.io/ryrocks/pen/zovXWy

In this example hover triggers the page flip, but you can modify that to be triggered by a Javascript click event and to show the page that you prefer when the event occurs.

-moz-transform-origin: 50% 100%;
-ms-transform-origin: 50% 100%;
transform-origin: 50% 100%;
-webkit-transform: rotate(0deg);
-moz-transform: rotate(0deg);
-ms-transform: rotate(0deg);
transform: rotate(0deg);
}
The ask is to be able to update the transform property for .ring-left:before and .ring-right:before via ReactJS.
If there is a way to not update the :before class and change the CSS to not make use of :before at all, then do suggest that as well.

You can iterate document.styleSheets, set .style of .cssRules where .selectorText matches pseudo selector
let sheets = document.styleSheets;
let selector = "div::before";
let replacementContent = '"after"';
for (let sheet of sheets) {
for (let rule of sheet.cssRules) {
if (rule.selectorText === selector) {
rule.style["content"] = replacementContent;
}
}
}
div:before {
content: "before";
color: red;
font-weight: bold;
text-align: center;
text-shadow: 2px 2px 2px #000;
background: green;
width: 50px;
height: 50px;
display: block;
}
<div></div>
