CSS Hover transition not working on my website [duplicate] - html

Question

It's a pretty straightforward question but I can't find very good documentation on the CSS transition properties. Here is the CSS snippet:
.nav a
{
text-transform:uppercase;
text-decoration:none;
color:#d3d3d3;
line-height:1.5 em;
font-size:.8em;
display:block;
text-align:center;
text-shadow: 0 -1.5em 0 rgba(255, 255, 255, 0.15);
-webkit-transition: color .2s linear;
-moz-transition: color .2s linear;
-o-transition: color .2s linear;
transition: color .2s linear;
-webkit-transition: text-shadow .2s linear;
-moz-transition: text-shadow .2s linear;
-o-transition: text-shadow .2s linear;
transition: text-shadow .2s linear;
}
.nav a:hover
{
color:#F7931E;
text-shadow: 0 1.5em 0 rgba(247, 147, 30, 0.15);
}
As you can see, the transition properties are overwriting eachother. As it stands, the text-shadow will animate, but not the color. How do I get them both to simultaneously animate? Thanks for any answers.

Answer 1

Transition properties are comma delimited in all browsers that support transitions:
.nav a {
transition: color .2s, text-shadow .2s;
}
ease is the default timing function, so you don't have to specify it. If you really want linear, you will need to specify it:
transition: color .2s linear, text-shadow .2s linear;
This starts to get repetitive, so if you're going to be using the same times and timing functions across multiple properties it's best to go ahead and use the various transition-* properties instead of the shorthand:
transition-property: color, text-shadow;
transition-duration: .2s;
transition-timing-function: linear;

EDIT: I'm torn on whether to delete this post. As a matter of understanding the CSS syntax, it's good that people know all exists, and it may at times be preferable to a million individual declarations, depending on the structure of your CSS. On the other hand, it may have a performance penalty, although I've yet to see any data supporting that hypothesis. For now, I'll leave it, but I want people to be aware it's a mixed bag.
Original post:
You can also simply significantly with:
.nav a {
transition: all .2s;
}
FWIW: all is implied if not specified, so transition: .2s; will get you to the same place.

Answer 3

If you make all the properties animated the same, you can set each separately which will allow you to not repeat the code.
transition: all 2s;
transition-property: color, text-shadow;
There is more about it here: CSS transition shorthand with multiple properties?
I would avoid using the property all (transition-property overwrites 'all'), since you could end up with unwanted behavior and unexpected performance hits.

Answer 4

Something like the following will allow for multiple transitions simultaneously:
-webkit-transition: color .2s linear, text-shadow .2s linear;
-moz-transition: color .2s linear, text-shadow .2s linear;
-o-transition: color .2s linear, text-shadow .2s linear;
transition: color .2s linear, text-shadow .2s linear;
Example: http://jsbin.com/omogaf/2

Answer 5

.nav a {
transition: color .2s, text-shadow .2s;
}

Answer 6

It's possible to make the multiple transitions set with different values for duration, delay and timing function. To split different transitions use ,
button{
transition: background 1s ease-in-out 2s, width 2s linear;
-webkit-transition: background 1s ease-in-out 2s, width 2s linear; /* Safari */
}

Answer 7

Here's a LESS mixin for transitioning two properties at once:
.transition-two(#transition1, #transition1-duration, #transition2, #transition2-duration) {
-webkit-transition: #transition1 #transition1-duration, #transition2 #transition2-duration;
-moz-transition: #transition1 #transition1-duration, #transition2 #transition2-duration;
-o-transition: #transition1 #transition1-duration, #transition2 #transition2-duration;
transition: #transition1 #transition1-duration, #transition2 #transition2-duration;
}

Answer 8

It's also possible to avoid specifying the properties altogether.
#box {
transition: 0.4s;
position: absolute;
border: 1px solid darkred;
bottom: 20px; left: 20px;
width: 200px; height: 200px;
opacity: 0;
}
#box.on {
opacity: 1;
height: 300px;
width: 500px;
}

Answer 9

In Sass you can achieve using below code
#mixin transition($transitions...) {
$unfoldedTransitions: ();
#each $transition in $transitions {
$unfoldedTransitions: append($unfoldedTransitions, unfoldTransition($transition), comma);
}
-webkit-transition: $unfoldedTransitions;
transition: $unfoldedTransitions;
}
#function unfoldTransition ($transition) {
// Default values
$property: all;
$duration: .2s;
$easing: null; // Browser default is ease, which is what we want
$delay: null; // Browser default is 0, which is what we want
$defaultProperties: ($property, $duration, $easing, $delay);
// Grab transition properties if they exist
$unfoldedTransition: ();
#for $i from 1 through length($defaultProperties) {
$p: null;
#if $i <= length($transition) {
$p: nth($transition, $i)
} #else {
$p: nth($defaultProperties, $i)
}
$unfoldedTransition: append($unfoldedTransition, $p);
}
#return $unfoldedTransition;
}
// Usage: #include transition(width, height 0.3s ease-in-out);
