I want to apply opacity: 1; to a Paragraph when hovering over itself (I have figured that out) and when I hover the header above it.
This is my CSS
.testH {
font-family: impact;
text-align: center;
font-size: 50px;
transition: all 1s;
}
.testP {
text-align: center;
opacity: 0.5;
font-size: 18px;
transition: all 1s;
}
#testHdiv:hover {
opacity: 1;
}
.testP:hover {
opacity: 1;
}
My HTML
<div id="testHdiv"><h1 class="testH"><b>< ></b></h1>
<p class="testP">Text and text, more text<br>Bla bla bla bla</p>
</div>
So, as you can see I try to get the opacity from the paragraphs current 0.5, to 1 when hovering the Div - my idea is: being able to hover a "box"/the div, and the text becomming less transparent. Though I think the opacity on the hover of the Div does not Work as the div is defined a Div, not text, and therefor can't be transparent?
I have been struggling with this for a while now. But I am basically wanting something like this: http://demo.web3canvas.com/themeforest/flathost/onepage/index.html#testimonials, where you hover within range of the text and it is being zoomed - in this case, just with opacity.
You can set a class to the <p> or just, use an operator to set the :hover to paragraph.
Example:
#testHdiv:hover > p {
opacity: 1;
}
http://jsfiddle.net/g97pusex/1/
Just change this:
#testHdiv:hover {
opacity: 1;
}
To be like that:
#testHdiv:hover p{
opacity: 1;
}
You'll want to apply the opacity to the p element, not the div. According to your provided style, you can change it to this:
.testH {
font-family: impact;
text-align: center;
font-size: 50px;
transition: all 1s;
}
.testP {
text-align: center;
opacity: 0.5;
font-size: 18px;
transition: all 1s;
}
#testHdiv:hover .testH {
opacity: 1;
}
#testHdiv:hover .testP {
opacity: 1;
}
Notice how the :hover selector is applied to the div, but the style is applied to the p element .testP
If you are trying to hover the div and on hover it affect the paragraph opacity change your CSS to:
#testHdiv:hover .testP{
opacity: 1;
}

I'm maybe 2 weeks into coding so apologies if I don't format correctly (code and question itself).I am trying to set a delay for the time it takes the buttons to switch text. Thank you for the help!
I've tried googling this and youtube with no luck.
I have tried adding
transition
transition-delay
body{
background-color: black;
}
.column{
position: fixed;
left:0;
bottom:0;
top:55px;
width:72px;
z-index: 200;
padding-top: 20px;
}
.about,
.skills {
font-size:72px;
width: 10em;
text-align: left;
border:none;
background-color: black;
color:red;
}
.about:hover span {
display: none;
}
.about:hover:after {
transition-delay: 3s;
content: "ABOUT";
}
.skills:hover span {
display: none
}
.skills:hover:after {
content: "SKILLS"
}
<h1>
<div class="column">
<button class="about" data-hover="ABOUT">
<span>
I
</span>
</button>
<button class="skills">
<span>
AM
</span>
</button>
</div>
</h1>
First of all, I would look into the html semantics a bit. Having div tags inside an h1 doesn't make much sense. So consider changing the h1 to a div. Also, the 3s delay is enormous. Think of something a bit faster, like 300ms.
The real issue is that display states and transition don't really work together since it swaps between states like block and none. But there are other solutions to this. You could use position: relative; on a parent div and give the children position: absolute. This way, you could make the transitions with opacity instead.
I have made an example for you so you can get the idea. I have commented on the CSS so you can follow up on what is happening.
/* Lets give our spans some styling: */
span{
font-size: 30px;
font-weight: 600;
font-family: sans-serif;
margin-bottom: 2rem;
max-width: 60ch;
}
/* Lets make the "container" position relative,
this way the absolute children will stay inside the container */
.hover-effect{
position: relative;
}
/* Let's give both of the children position absolute */
.hover-effect span{
position: absolute;
color: black;
opacity: 100%;
transition: 300ms ease-in 300ms; /* Delay: 300ms*/
}
/* Let’s override the previous.
This actually happens when we remove the hover, so we want to
trigger this animation first, hence the delay of 0ms*/
.hover-effect span.on-hover{
opacity: 0%;
transition: 300ms ease-in 0ms;
}
/* When we hover the container, let's change both spans */
.hover-effect:hover span{
color: red;
opacity: 0%;
transition-delay: 0ms;
}
/* Let’s override the previous.
When we hover on the container, the span with the class "on-hover"
becomes visible, and we wait 300ms before it happens so that the
"disappearing" animation gets its time to trigger. */
.hover-effect:hover span.on-hover{
opacity: 100%;
transition-delay: 300ms;
}
<div class="hover-effect">
<span>Try and hover over me</span>
<span class="on-hover">Try and remove the hover</span>
</div>
I cannot figure out why this breaks it. I have an a element which uses CSS transitions to fade into a gradient background on hover. For whatever reason whenever I set the text color on hover to white the transition breaks?
.social-item {
margin-left: 0.25vw;
padding: 0.1vw;
transition: 0.2s;
color: white;
}
.social-item:hover {
background: linear-gradient(to left, #8E2DE2, #DC0486);
color: white;
}
<i class="fab fa-keybase"></i> Keybase
I'm also using Bulma and Font Awesome.
You can't simply make transitions with background gradients.
Animatable CSS Properties
Use pseudo-element and do an opacity transform.
.social-item {
position: relative;
color: white;
z-index: 1;
}
.social-item::before {
position: absolute;
content: "";
top: 0;
right: 0;
bottom: 0;
left: 0;
background-image: linear-gradient(to left, #8e2de2, #dc0486);
z-index: -1;
transition: opacity 0.5s linear;
opacity: 0;
}
.social-item:hover::before {
opacity: 1;
}
<i class="fab fa-keybase"></i> Keybase
A nice article about this.
Thank you!
What I figured your problem to be is that you're trying to do gradient transition. It is not supported. But if you want to simulate it, you can use the opacity property in css. Add opacity: 0 to the main element (.social-item) and opacity: 1 to the hover state (.social-events:hover). Hence the transition: 0.2 will apply on the opacity, as it is supported, thus simulating the desired outcome.
Thus the final css, shall be.
.social-item {
margin-left: 0.25vw;
padding: 0.1vw;
transition: 0.2s;
color: white;
opacity:0;
}
.social-item:hover {
background: linear-gradient(to left, #8E2DE2, #DC0486);
color: white;
opacity: 1;
}
If you actually want to have the thing display normally, and not just on hover, then opacity: 0 wont work for you. You have to use the pseudo-selector :after to add a dummy element to the main class and work all the transitions and background gradient stuff on that. Here is a codepen example.
I use this hover-effect, where everything but the hovered Element fades out, you can see it in the snippet below.
Its working in Firefox (Version 66.0.3 ) but not in Chrome (Version 73.0.3683.103). I also tried Microsoft Edge, it works there aswell.
I tried adding "-webkit-" because I read, that this could fix the problem, but it didn´t.
Anybody an idea how to achieve this hover-effect in Chrome?
.links{
font-weight: bold;
font-size: 20px;
}
/* Hover Effect */
.hover {
visibility: hidden;
}
.hover > * {
visibility: visible;
transition: opacity 100ms linear 100ms;
}
.hover:hover > * {
opacity: 0.3;
}
.hover > *:hover {
opacity: 1;
transition-delay: 0ms, 0ms;
}
EDIT:
It works in Chrome, if I remove the links (in my case references to other pages of the website).
Working in Chrome:
.links {
font-weight: bold;
font-size: 20px;
}
/* Hover Effect */
.hover {
visibility: hidden;
}
.hover>* {
visibility: visible;
transition: opacity 100ms linear 100ms;
}
.hover:hover>* {
opacity: 0.3;
}
.hover>*:hover {
opacity: 1;
transition-delay: 0ms, 0ms;
}
<div class="links">
<div class="hover">
<div class="linkNav">1</div>
<div class="linkNav">2</div>
<div class="linkNav">3</div>
</div>
</div>
Not Working in Chrome:
.links {
font-weight: bold;
font-size: 20px;
}
/* Hover Effect */
.hover {
visibility: hidden;
}
.hover>* {
visibility: visible;
transition: opacity 100ms linear 100ms;
}
.hover:hover>* {
opacity: 0.3;
}
.hover>*:hover {
opacity: 1;
transition-delay: 0ms, 0ms;
}
<div class="links">
<div class="hover">
<a href="1.html">
<div class="linkNav">1</div>
</a>
<a href="2.html">
<div class="linkNav">2</div>
</a>
<a href="3.html">
<div class="linkNav">3</div>
</a>
</div>
</div>
(N.b. I have updated this answer after noting the problem with the HTML).
I simplified your CSS to try and isolate the problem (I removed the visibility properties that aren't doing anything as well as the > * selectors)
It's unsurprising there is unpredictable behaviour in this case because strictly speaking you shouldn't be putting a block level element such as <div> inside an <a> element.
It seems that, in this case of malformed HTML, Chrome won't recognise the opacity value of the anchor (<a>) tag unless I do something like set it to display: block or display:inline-block. FireFox, Edge and IE do recognise the opacity regardless.
The best solution would be to fix your HTML so that the block level elements wrap the inline elements properly.
.links {
font-weight: bold;
font-size: 20px;
}
.hover:hover a {
opacity: 0.3;
}
.hover a:hover {
opacity: 1;
}
<div class="links hover">
<div class="linkNav">1</div>
<div class="linkNav">2</div>
<div class="linkNav">3</div>
</div>
I would recommend fixing it like this but if for some reason you can't fix the HTM a workaround is to set the display property on your anchor tags. Like so:
.links {
font-weight: bold;
font-size: 20px;
}
.links a {
display:block;
}
.hover:hover a {
opacity: 0.3;
}
.hover a:hover {
opacity: 1;
}
<div class="links hover">
<div class="linkNav">1</div>
<div class="linkNav">2</div>
<div class="linkNav">3</div>
</div>
Or else an alternative solution is you could simply target an alternative element, such as the inner div instead of the a tag.
JSFiddle links for the different workaround solutions and the original CVE that demonstrates the issue (useful for testing in different browsers):
Solution by setting display block
Solution by changing selector to target inner div
Original CVE which works in most browsers but not Chrome
I have corrected the code
the problem here was in the ordering you were adding HTML
The a tag has div inside it and class on that which the selector on hover was unable to reach to.
Now see, it works fine.
This is it I guess.
Hope it solves your problem.
.links {
font-weight: bold;
font-size: 20px;
}
/* Hover Effect */
.hover {
visibility: hidden;
}
.hover>* {
visibility: visible;
transition: opacity 100ms linear 100ms;
}
.hover:hover>* {
opacity: 0.3;
}
.hover>*:hover {
opacity: 1;
transition-delay: 0ms, 0ms;
}
<div class="links">
<div class="hover">

3
</div>
</div>
I was trying to make a text box appear when I hovered over something different.
In my code: I want to hover over the h1 block and make the h3 block appear.
h1.title {
font-size: 100px;
background: url(https://upload.wikimedia.org/wikipedia/commons/f/f3/Orion_Nebula_-_Hubble_2006_mosaic_18000.jpg);
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
transition: 5.6s ease, 3s transform;
}
h1.title:hover {
background-position: left;
transform: translateX(150px) /* Where the .ps would appear */
}
.ps {
visibility: hidden;
}
<div class="title">
<h1 class="title">Random Thing</h1>
<h3 class="ps">Playing around in HTML!</h3>
</div>
You can use the adjacent sibling combinator +:
https://www.w3.org/TR/css3-selectors/#adjacent-sibling-combinators
h1.title:hover + .ps {
visibility: visible;
}
First of all, comments in css are made by
/* text */
The answer to your question:
h1.title:hover + .ps {
display: block;
}
Don't use visibility styling because when I used it before it didn't work. And display is more common.
Hope this works!
You can also use
h1.title:hover + #ps {
opacity: 1;
}
Sometimes I can't use a dot when making code that represents an element with an id.
I have a blockquote like this:
<blockquote class="spoiler">Soopah sekkrit!</blockquote>
I want to make it hidden, only showing it if the user hovers over it. I'm doing it now with JS:
blockquote.addEventListener('mouseover', function() {
this.style.height = this.offsetHeight + 'px';
this.dataset.contents = this.innerHTML;
this.innerHTML = '';
});
blockquote.addEventListener('mouseout', function() {
this.style.height = '';
this.innerHTML = this.dataset.contents;
});
Is there a better way to do this, with CSS?
It has to keep its background-color, size, and work for contents with custom colors. If possible, I'd also like to animate it so the contents fade in gradually.
Here's something very similar to what I use in SOUP:
.spoiler, .spoiler > * { transition: color 0.5s, opacity 0.5s }
.spoiler:not(:hover) { color: transparent }
.spoiler:not(:hover) > * { opacity: 0 }
/* fix weird transitions on Chrome: */
blockquote, blockquote > *:not(a) { color: black }
.spoiler, .spoiler > * { transition: color 0.5s, opacity 0.5s }
.spoiler:not(:hover) { color: transparent }
.spoiler:not(:hover) > * { opacity: 0 }
/* fix weird transitions on Chrome: */
blockquote, blockquote > *:not(a) { color: black }
/* some basic bg styles for demonstration purposes */
blockquote { background: #fed; margin: 1em 0; padding: 8px; border-left: 2px solid #cba }
code { background: #ccc; padding: 2px }
img { vertical-align: middle }
<blockquote class="spoiler">
Soopah sekkrit text with <code>code</code> and links and <img src="//sstatic.net/stackexchange/img/logos/so/so-logo-med.png" width="100" /> images!
<p>You can also have paragraphs in here.</p>
<ul><li>And lists too!</li></ul>
<blockquote class="spoiler">Even nested spoilers work!</blockquote>
</blockquote>
This is somewhat simpler than your own solution, and works for arbitrary content including images and even nested spoilers! (See demo snippet above.)
Alas, this method seems to suffer from weird transition effects on Chrome if any of the child elements of the spoiler have color: inherit. (Basically, what's happening is that these elements will have both their text color set to transparent and their opacity set to 0. Because opacities combine multiplicatively, the combined transition will thus appear slower — halfway through the fade-in, when the element itself is at 50% opacity, the text in it is at 50% × 50% = 25% opacity.) I've added an extra CSS rule to the example above to fix this, but it does make things a bit complicated.
What I actually do in SOUP is slightly different. I wrap the contents of each spoiler in an extra inner <div>, which lets me simplify the CSS further to just:
.spoiler > div { opacity: 0; transition: opacity 0.5s }
.spoiler:hover > div { opacity: 1 }
.spoiler > div { opacity: 0; transition: opacity 0.5s }
.spoiler:hover > div { opacity: 1 }
/* some basic bg styles for demonstration purposes */
blockquote { background: #fed; margin: 1em 0; padding: 8px; border-left: 2px solid #cba }
code { background: #ccc; padding: 2px }
img { vertical-align: middle }
<blockquote class="spoiler"><div>
Soopah sekkrit text with <code>code</code> and links and <img src="//sstatic.net/stackexchange/img/logos/so/so-logo-med.png" width="100" /> images!
<p>You can also have paragraphs in here.</p>
<ul><li>And lists too!</li></ul>
<blockquote class="spoiler"><div>Even nested spoilers work!</div></blockquote>
<div></blockquote>
The main advantages of this method are simplicity and robustness: I don't have to use :not() selectors, improving compatibility with older browsers, and the transition styles can't conflict with other transitions possibly defined on the elements inside the spoiler. This method also doesn't suffer from the color transition weirdness on Chrome described above, since it only uses opacity transitions.
Overall, this is the method I recommend. The disadvantage, of course, is that you need to include the extra <div>s in your HTML.
Ps. Please consider also providing some way to make the spoilers permanently visible, especially for touch screen users who may find it very hard to "hover" the cursor over an element. A simple solution is to use a JavaScript click event handler to toggle the spoiler class, e.g. like this (using jQuery):
$('.spoiler').on( 'click', function (e) {
$(this).toggleClass('spoiler');
e.stopPropagation();
} );
$('.spoiler').on( 'click', function (e) {
$(this).toggleClass('spoiler');
e.stopPropagation();
} );
.spoiler > div { opacity: 0; transition: opacity 0.5s }
.spoiler:hover > div { opacity: 1 }
/* some basic bg styles for demonstration purposes */
blockquote { background: #fed; margin: 1em 0; padding: 8px; border-left: 2px solid #cba }
code { background: #ccc; padding: 2px }
img { vertical-align: middle }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<blockquote class="spoiler"><div>
Soopah sekkrit text with <code>code</code> and links and <img src="//sstatic.net/stackexchange/img/logos/so/so-logo-med.png" width="100" /> images!
<p>You can also have paragraphs in here.</p>
<ul><li>And lists too!</li></ul>
<blockquote class="spoiler"><div>Even nested spoilers work!</div></blockquote>
<div></blockquote>
or, if you'd prefer to use delegated event handling (so that you don't have to keep adding new click handlers every time you load new content that includes spoilers via Ajax):
$(document).on( 'click', '.spoiler, .spoiler-off', function (e) {
$(this).toggleClass('spoiler').toggleClass('spoiler-off');
e.stopPropagation();
} );
$(document).on( 'click', '.spoiler, .spoiler-off', function (e) {
$(this).toggleClass('spoiler').toggleClass('spoiler-off');
e.stopPropagation();
} );
.spoiler > div { opacity: 0; transition: opacity 0.5s }
.spoiler:hover > div { opacity: 1 }
/* some basic bg styles for demonstration purposes */
blockquote { background: #fed; margin: 1em 0; padding: 8px; border-left: 2px solid #cba }
code { background: #ccc; padding: 2px }
img { vertical-align: middle }

(These should work with either of the CSS variants shown above.)
Yes, this is possible with CSS. Essentially, you want to make all of the contents be invisible. In CSS, this means transparent.
First use the hover pseudo-class inside the not pseudo-class:
.spoiler:not(:hover)
But we also need to select all the child elements of the hovered spoiler, to set their colors and backgrounds:
.spoiler:not(:hover) *
And we set both the color and background (only for the child elements) to transparent to make them invisible to the user. All together:
.spoiler:not(:hover), .spoiler:not(:hover) * { color: transparent }
.spoiler:not(:hover) * { background: transparent }
code { padding: 2px; background: #bbb }
a { color: #00f }
Hover: <blockquote class="spoiler">Some stuff <a>and a colored link</a> <code>and some code!</code></blockquote>
We can also add a transition to make it smoother:
.spoiler { transition: color 0.5s } /* we have to put this outside the :hover to make it work fading both in and out */
.spoiler:not(:hover), .spoiler:not(:hover) * { color: transparent }
.spoiler * { transition: color 0.5s, background 0.5s }
.spoiler:not(:hover) * { background: transparent }
code { padding: 2px; background: #bbb; color: #000 } /* add color to prevent double transition */
a { color: #00f }
Hover: <blockquote class="spoiler">Some stuff <a>and a colored link</a> <code>and some code!</code></blockquote>
To make it obvious to the user that the blockquote is hoverable, you can add some text with the ::after pseudo-element to be shown when the blockquote isn't hovered:
.spoiler { transition: color 0.5s; position: relative } /* relative position for positioning the pseudo-element */
.spoiler:not(:hover), .spoiler:not(:hover) * { color: transparent }
.spoiler * { transition: color 0.5s, background 0.5s }
.spoiler:not(:hover) * { background: transparent }
.spoiler::after {
content: 'hover to view spoiler';
position: absolute;
top: 0; left: 0;
color: transparent;
}
.spoiler:not(:hover)::after {
color: #666;
transition: color 0.3s 0.3s; /* delayed transition to keep the text from overlapping */
}
code { padding: 2px; background: #bbb; color: #000 }
a { color: #00f }
<blockquote class="spoiler">
Some stuff <a>and a colored link</a> <code>and some code!</code>
<blockquote class="spoiler">Nesting bonus!</blockquote>
</blockquote>
For stuff like images, svgs (tho inline SVG can be very granularly controlled), canvases, and all that fancy stuff, instead of color you'd have to use opacity. We can make it work with these by adding this:
.spoiler img { transition: opacity 0.5s, background 0.5s }
.spoiler:not(:hover) img { opacity: 0 }
Here's a strategy that works pretty well, looks nice, and has pretty clean transitions
.spoiler {
position: relative;
display: inline-block;
cursor: help;
}
.spoiler::before {
content: 'psst\02026'; /* … */
position: absolute;
left: -2px;
top: -2px;
right: -2px;
bottom: -2px;
border-radius: 1px;
font-size: .9rem;
color: #e6578c;
background: #ffe5e5;
display: flex;
align-items: center;
justify-content: center;
text-align: center;
opacity: 1;
transition: opacity 0.7s ease, transform 0.3s ease; /* hide faster than reveal */
}
.spoiler:hover::before {
opacity: 0;
transform: translateY(-50%)rotateX(80deg);
transition: opacity 1.0s ease, transform 0.5s ease; /* slower reveal */
}
If you style the parent block with opacity: 0 without hover, then you can't add any styles to illustrate what part of the page the user should be hovering over.
Instead, if we add a ::before element that covers up the child content, then we can fade it out on hover and still provide a visual indication of where to go.
