please take a look at this example:
https://www.outsideonline.com/2317131/wilma-rudolph-worlds-fastest-woman
Note that when you hover over link, the background animated to fill the anchor text from bottom to top, and clears is from top to bottom when you hover away from it.
I've done something similar with my own website. The relevant CSS for it:
a {
box-shadow: inset 0 -3px 0 -1px #FFF986;
-webkit-transition: box-shadow .15s ease-in-out;
transition: box-shadow .15s ease-in-out;
color: black;
}
a:hover {
box-shadow: inset 0 -3px 0 40px #FFF986;
-webkit-transition: box-shadow .15s ease-in-out;
transition: box-shadow .15s ease-in-out;
}
This gives me a similar effect, but instead of filling from top to bottom like in the example link: The background starts to fill from all sides of the rectangle toward to center.
How do I force it to fill from top to bottom, like in the example link I shared? what am I missing?
You're changing wrong parameter:
a:hover {
box-shadow: inset 0 -40px 0 -1px #FFF986;
a {
box-shadow: inset 0 -3px 0 -1px #FFF986;
transition: box-shadow .15s ease-in-out;
color: black;
line-height: 40px;
}
a:hover {
box-shadow: inset 0 -40px 0 -1px #FFF986;
}
Hey Mickey!
Another solution that uses a 50%/50% linear gradient resized to 200%. To animate the background change the background position:
a {
background-image: linear-gradient(to top, yellow 50%, transparent 50%);
background-size: 100% 200%;
background-position: top;
transition: background-position 0.5s ease-in-out; /** I've changed the time for demo purposes **/
color: black;
}
a:hover {
background-position: bottom;
}
I'm a link
I'm another link
a {
box-shadow: inset 0 -3px 0 -1px #FFF986;
transition: box-shadow .15s ease-in-out;
color: black;
line-height: 40px;
}
a:hover {
box-shadow: inset 0 -40px 0 -1px #FFF986;
}

Use CSS3 transitions with gradient backgrounds
(19 answers)
Closed 1 year ago.
I'm trying to add a transition to a button I have that's background is made with css linear-gradient but it's not working.
This is the css for my button.
a.button
{
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#green), color-stop(100%,#a5c956));
-webkit-transition: background 5s linear;
}
a.button:hover
{
-webkit-gradient(linear, left top, left bottom, color-stop(0%,#greenhover), color-stop(100%,#89af37))
}
If you're wondering about #green and #greenhover, I'm using .less to make my css.
Anything wrong with this? Any ideas?
Sadly, you really can't transition gradients for now.
So, the only workable workaround is using an extra element with needed gradient and transition it's opacity:
a.button {
position: relative;
z-index: 9;
display: inline-block;
padding: 0 10px;
background: -webkit-gradient(linear, 0 0, 0 100%, from(green), to(#a5c956));
background: -webkit-linear-gradient(top, green, #a5c956);
background: -moz-linear-gradient(top, green, #a5c956);
background: -o-linear-gradient(top, green, #a5c956);
background: linear-gradient(top, green, #a5c956);
}
.button-helper {
position: absolute;
z-index: -1;
top: 0;
left: 0;
width: 100%;
height: 100%;
opacity: 0;
background: -webkit-gradient(linear, 0 0, 0 100%, from(lime), to(#89af37));
background: -webkit-linear-gradient(top, lime, #89af37);
background: -moz-linear-gradient(top, lime, #89af37);
background: -o-linear-gradient(top, lime, #89af37);
background: linear-gradient(top, lime, #89af37);
-webkit-transition: opacity 1s linear;
-moz-transition: opacity 1s linear;
-o-transition: opacity 1s linear;
transition: opacity 1s linear;
}
a.button:hover .button-helper {
opacity: 1;
}
<span class="button-helper"></span>button
it's tricky.. and of course tricky is cool ;)
okay.. i got a solution. and it's basically done via amazing :before selector
#cool-hover{
width: 120px;
height: 120px;
display: block;
cursor: pointer;
border-radius: 10px;
box-shadow: 0 0 15px rgba(0,0,0,0.3);
margin: 0px auto 24px auto;
transition: all 0.5s;
position: relative;
overflow: hidden;
}
#cool-hover:before{
border-radius: inherit;
display: block;
width: 200%;
height: 200%;
content: '';
position: absolute;
top: 0;
left: 0;
background: linear-gradient(135deg, #21d4fd 25%, #b721ff 75%);
transition: all 0.5s;
transform: translate(-25%, -25%);
z-index: 0;
}
#cool-hover:after{
border-radius: 9px;
display: block;
width: 108px;
height: 108px;
margin: 6px;
background: url('https://i.imgur.com/w0BjFgr.png');
background-size: cover;
content: '';
position: absolute;
top: 0; left: 0;
z-index: 1;
}
#cool-hover:hover:before{
transform: translate(-25%, -25%) rotate(-180deg);
}
#cool-hover:hover{
box-shadow: 0 0 35px rgba(0,0,0,0.3);
}
<div id="cool-hover"></div>
NOTE : i just added the :after sudo class just for the small on top image placeholder purpose..
have a nice awesome styling ;)
I know this pretty old but I could not find any good solution yet. So here is my solution
First Make gradient on ":before and hide it with opacity then transition opacity 1 on hover.
https://jsfiddle.net/sumon380/osqLpboc/3/
.button {
text-decoration: none;
padding: 10px 25px;
font-size: 20px;
color: #333;
display: inline-block;
background: #d6e9eb;
position: relative;
z-index: 1;
transition: color 0.3s ease-out;
}
.button:before {
background: #91a5f4;
background: linear-gradient(135deg, #91a5f4 0%, #b08cf9 86%);
content: "";
width: 100%;
height: 100%;
top: 0;
left: 0;
position: absolute;
z-index: -1;
opacity: 0;
transition: opacity 0.3s ease-out;
}
.button:hover:before {
opacity: 1;
}
.button:hover {
color: #fff;
}
<a class="button" href="#">Button</a>
You can fake gradient transitions using drop shadows!
For instance, from one of my pages:
c {
color: #FFF;
background: #000;
border-style:solid;
border-color:#CCC;
border-width: 0 0 0 1px;
box-shadow: 2px 2px 2px #555, inset 0 25px 20px -10px rgba(255, 255, 255, 0.3),
inset 0 -15px 20px -10px rgba(0, 0, 0, 0.15);
-moz-box-shadow: 2px 2px 2px #555, inset 0 25px 20px -10px rgba(255, 255, 255, 0.3),
inset 0 -15px 20px -10px rgba(0, 0, 0, 0.15);
-o-box-shadow: 2px 2px 2px #555, inset 0 25px 20px -10px rgba(255, 255, 255, 0.3),
inset 0 -15px 20px -10px rgba(0, 0, 0, 0.15);
-webkit-box-shadow: 2px 2px 2px #555,
inset 0 25px 20px -10px rgba(255, 255, 255, 0.3),
inset 0 -15px 20px -10px rgba(0, 0, 0, 0.15);
-moz-transition: background-color .5s ease;
-o-transition: background-color .5s ease;
-webkit-transition: background-color .5s ease-in-out;
transition: background-color .5s ease;
}
Followed by:
c:hover {
color:#FFF;
background: #505;
position:relative;
top:1px;
box-shadow: -1px -1px -1px #555,inset 0 20px 20px -10px rgba(0, 0, 0, 0.15),
inset 0 -15px 20px -10px rgba(255, 255, 255, 0.3);
-moz-box-shadow: -1px -1px -1px #555,inset 0 20px 20px -10px rgba(0, 0, 0, 0.15),
inset 0 -15px 20px -10px rgba(255, 255, 255, 0.3);
-o-box-shadow: -1px -1px -1px #555, inset 0 20px 20px -10px rgba(0, 0, 0, 0.15),
inset 0 -15px 20px -10px rgba(255, 255, 255, 0.3);
-webkit-box-shadow: 1px -1px -1px #555, inset 0 20px 20px -10px rgba(0, 0, 0, 0.15),
inset 0 -15px 20px -10px rgba(255, 255, 255, 0.3);
}
Here, you are essentially using an inset shadow as a Photoshop-like mask, causing a gradient effect on the underlying element. On hover, you invert the effect.
If you're doing the slight highlight when hovering the button there is a much simpler solution. You can just nudge the gradient down a bit and have the background-color be the same as the top color of your gradient: http://cdpn.io/oaByI
It's pretty limited I know, but if works well for that use case.
I know this question is pretty old, but I found a good way to animate basic gradients that will work in some cases.
This method will let you animate a change in color of the gradient but not a change in the position of the color stops.

9 years, but this time, hope my styled-components can help someone:
import React, { ReactNode } from 'react'
import { Button as ButtonUI } from "#your-library-ui"
import styled from 'styled-components'
type Props = {
onClick?: () => void;
children?: ReactNode;
};
const Button = ({onClick, children}: Props) => (
<StyledButton onClick={onClick} >
{children}
<ButtonHelper />
</StyledButton>
)
export default Button
const ButtonHelper = styled.span`
position: absolute;
z-index: -1;
top: 0;
left: 0;
width: 100%;
height: 100%;
opacity: 0;
border-radius: 5px;
background: linear-gradient(to right, #5ab0f4, #1273ea)!important;
transition: opacity 0.2s linear;
`;
const StyledButton = styled(ButtonUI)`
position: relative;
z-index: 1;
background: linear-gradient(to right, #1273ea, #1c94f4)!important;
color: #fff;
&:hover ${ButtonHelper} {
opacity: 1;
}
`;
And start using your new designed component with extra effect! Thanks to #kizu for the suggestion.
you must have same style in source and changed style in target.
like
a {
background: transparent;
background: linear-gradient(transparent,transparent);
-moz-transition: all 0.3s ease;
-o-transition: all 0.3s ease;
-webkit-transition: all 0.3s ease;
transition: all 0.3s ease;
}
a:hover
{
background: #abc07c;
background: linear-gradient(#c5db95,#88a743);
}
Today I updated Firefox to version 45 (current). After that I started to have problems with scaling thumbnails located in div with overflow: hidden. On mouseover the thumbnail for a millisecond scaling down and after this doing correct action . When you hover mouse the thumbnail second time, everything is working properly. The problem returns after clearing the browser cache or a long time without mouse over the thumbnail. The funny thing is that on other browsers working properly(Chrome, Opera).
[CSS]
.galleryimg {
height: 200px;
width: 200px;

box-shadow:

}

Shadows work properly on all elements, on IE and Firefox, but not for the button element in Chrome and Safari:
http://jsfiddle.net/q8xaa/
<button class="btn-test">
<span class="btn">test</span>
</button>
.btn-test {
background-color: transparent;
border: 0;
padding: 0px;

.btn-test:hover .btn {
-webkit-box-shadow: none;

}
.btn-test .btn {
-webkit-transition: all 0.2s linear;
-moz-transition: all 0.2s linear;
-ms-transition: all 0.2s linear;
-o-transition: all 0.2s linear;
transition: all 0.2s linear;
-webkit-box-shadow: 4px 4px 0px #000;
-moz-box-shadow: 4px 4px 0px #000;
box-shadow: 4px 4px 0px #000;
background-color: #f00;
margin: 0px;
padding: 10px;
height: 40px;
display: inline-block;
}
button {
margin: 0;
padding: 0;
border: 0;

}
Any ideas on how to solve?
Example http://jsfiddle.net/H23Jy/1/
I tried forcing a zero CSS3 transformation as shown below
CSS
button span {
-webkit-transform: translate3d(0,0,0);
}
and the shadow seems to work fine also on Chrome 35.
But as you can see, in that way the button is not vertically aligned with the other buttons, so you could use -webkit-transform: translateY(-3px); instead
Result
