Why does my progress bar animation change state when completed? - html

I have created a really simple animation which depletes a progress bar using CSS animations.
The problem I am having is once the bar is at 0% (where it should end, it then ends with the bar at 100% again)
.w3-progress-container {
width: 100%;
height: 3px;
position: relative;
background-color: #757575;
}
.w3-progressbar {
background-color: #FBCE07;
height: 100%;
position: absolute;
line-height: inherit;
animation: countdown 10s 1;
-webkit-animation: countdown 10s 1;
animation-timing-function: linear;
}
#-webkit-keyframes countdown {
0% { width:100%; }
100% { width: 0%; }
}
<div class="w3-progress-container">
<div id="myBar" class="w3-progressbar w3-green" style="width:100%"></div>
</div>

Remove the style="width:100%;" and it works.
At a guess, once the animation is complete, It reverts back to its original styling.

The animation-fill-mode property sets the state of the end animation when the animation is not running. Article by David Walsh Article on MDN
.w3-progress-container {
width: 100%;
height: 3px;
position: relative;
background-color: #757575;
}
.w3-progressbar {
background-color: #FBCE07;
height: 100%;
position: absolute;
line-height: inherit;
animation: countdown 10s 1;
-webkit-animation: countdown 10s 1;
animation-timing-function: linear;
animation-fill-mode: forwards;
}
#-webkit-keyframes countdown {
0% { width:100%; }
100% { width: 0%; }
}
<div class="w3-progress-container">
<div id="myBar" class="w3-progressbar w3-green" style="width:100%"></div>
</div>

You have to specify that the animation stay at its final state when it's over:
.w3-progressbar {
...
animation-fill-mode: forwards;
}

CSS ::after if visible at start then disseapering at middle and reappearing at end why?

CSS ::after if visible at the start then disappearing in the middle and reappearing at the end why? I want it to be visible throughout the animation equally like a horizontal slider
Here is my code:
.btn {
all: inherit;
position: relative;
font-size: 6rem;
}
.btn::after {
overflow: visible !important;
content: "";
position: absolute;
top: 0;
left: -5%;
height: 100%;
width: 2%;
background-color: greenyellow;
animation-name: LeftToRight;
animation-fill-mode: forwards;
animation-duration: 1s;
animation-iteration-count: infinite;
animation-timing-function: linear;
}
#keyframes LeftToRight {
0% {
left: -5%;
}
100% {
left: 105%;
}
}
<button class="btn">UNIVERSE</button>

Keyframe css animation

Question
let's if i have the following example
A-------------B------------C
how i can start an animation from the middle ( B ) then it go to A then to B and finaly it go to C , i made an example but it's not working good.
Code
.container {
display: block;
}
.container .line {
display: block;
height: 1px;
width: 400px;
background: red;
}
.line:after{
content: "";
height: 20px;
width: 20px;
display: block;
background: black;
border-radius: 50%;
position: absolute;
left: 200px;
top: 0px;
}
#keyframes move {
0% {
left: 200px;
}
25%{
left: 0px;
}
100%{
left: 400px;
}
}
.line:after {
-webkit-animation: move 1s alternate infinite;
-moz-animation: move 1s alternate infinite;
-ms-animation: move 1s alternate infinite;
-o-animation: move 1s alternate infinite;
animation: move 1s alternate infinite;
}
<div class="container">
<div class="line"></div>
</div>
If you do it this way, I thinks it's working well.
In stead of alternate I did use linear. It makes the animation smoother.
.container {
display: block;
}
.container .line {
display: block;
height: 1px;
width: 400px;
background: red;
}
.line:after{
content: "";
height: 20px;
width: 20px;
display: block;
background: black;
border-radius: 50%;
position: absolute;
left: 200px;
top: 0px;
}
#keyframes move {
0% {
left: 200px;
}
25%{
left: 0px;
}
75%{
left: 400px;
}
100%{
left: 200px;
}
}
.line:after {
-webkit-animation: move linear 1s infinite;
-moz-animation: move linear 1s infinite;
-ms-animation: move linear 1s infinite;
-o-animation: move linear 1s infinite;
animation: move linear 1s infinite;
}
<div class="container">
<div class="line"></div>
</div>
You could do it like this, also if add linear (because default is ease) you will get something like this Fiddle
.container .line {
height: 1px;
width: 400px;
background: red;
}
.line:after{
content: "";
height: 20px;
width: 20px;
background: black;
border-radius: 50%;
position: absolute;
left: 200px;
top: 0px;
animation: move 3s infinite;
}
#keyframes move {
0% {left: 200px;}
25%{left: 0px;}
50% {left: 200px;}
75% {left: 400px;}
100%{left: 200px;}
}
<div class="container">
<div class="line"></div>
</div>

Css - Multi Animated Progress Bar with Different Progress Percentages

I have an Animated Progress Bar that works fine, but I want to have more than one with different percentages I have had a go at this with no look I have added a jsfiddle below.
Jsfiddle Demo: https://jsfiddle.net/8sja2577/
<p><span class="subtitle"><h3>bar1</h3></span></p>
<div id="progressbar"><div id="other" ><div id="pbaranim"></div></div></div>
<p><span class="subtitle"><h3>bar2</h3></span></p>
<div id="progressbar"><div id="progress" ><div id="pbaranim"></div></div></div>
CSS
#progressbar {
width: 100%;
height: 21px;
background-color: #ccc;
padding: 2px;
margin: .6em 0;
border: 1px #000 double;
clear: both;
border-radius:20px;
}
#progress {
border-radius:20px;
background: red; /*-- Color of the bar --*/
height: 15px;
width: 0%;
max-width: 100%;
float: left;
-webkit-animation: progress 2s 1 forwards;
-moz-animation: progress 2s 1 forwards;
-ms-animation: progress 2s 1 forwards;
animation: progress 2s 1 forwards;
}
#other {
border-radius:20px;
background: red; /*-- Color of the bar --*/
height: 15px;
width: 0%;
max-width: 100%;
float: left;
-webkit-animation: progress 2s 1 forwards;
-moz-animation: progress 2s 1 forwards;
-ms-animation: progress 2s 1 forwards;

}
#pbaranim {
height: 15px;
width: 100%;
overflow: hidden;
background: url('http://www.cssdeck.com/uploads/media/items/7/7uo1osj.gif') repeat-x;
-moz-opacity: 0.25;
-khtml-opacity: 0.25;
opacity: 0.25;
-ms-filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=25);
filter: progid:DXImageTransform.Microsoft.Alpha(opacity=25);
filter: alpha(opacity=25);
#-webkit-keyframes other { from { } to { width: 100% }}
#-moz-keyframes other { from { } to { width: 100% }}
#-ms-keyframes other { from { } to { width: 100% }}
#keyframes other { from { } to { width: 100% }}
#-webkit-keyframes progress { from { }to { width: 36% }}
#-moz-keyframes progress { from { } to { width: 36% }}
#-ms-keyframes progress { from { } to { width: 36% }}
#keyframes progress { from { } to { width: 36% }}
You need to change the other style to use the other animation:
#other {
border-radius:20px;
background: red;
height: 15px;
width: 0%;
max-width: 100%;
float: left;
-webkit-animation: other 2s 1 forwards;
-moz-animation: other 2s 1 forwards;
-ms-animation: other 2s 1 forwards;
animation: other 2s 1 forwards;
}
Fixed fiddle (using classes instead of ids)
Please note that ids should be unique and h3 cannot be a child of either a p or a span
Id of progressbars is uniqe , you must change other progressbars id to work it successfully

Move Image across using CSS3 animation

I am trying to slide an image across the screen and then stay at a fixed point. I have looked online and found a few variants on what I have but nothing seems to work.
Have a look at this fiddle.
http://jsfiddle.net/lharby/ysgzpuer/
I had to pass in
-webkit-animation: mini 2s normal;
-moz-animation: mini 3s normal;
-o-animation: mini 3s normal;
animation: mini 2s normal;
to the .mini class to animate the div.
Update: This also has the opacity animated:
http://jsfiddle.net/lharby/ysgzpuer/1/
By editing:
#-webkit-keyframes mini {
from {
left:0px;
opacity:0;
}
to{
left:404px;
opacity:1;
}
#-webkit-keyframes mini {
from {
left:-166px;
}
}
.mini {
background-image: url("http://placehold.it/150x150");
position: absolute;
top: 10px;
left: 404px;
width: 166px;
height: 70px;
z-index: 7;
-webkit-animation: mini 2s linear;
}
<div class=mini></div>
Or this if you don't have overflow: hidden on the parent to avoid the scrollbar
#-webkit-keyframes mini {
from {
left:0px;
-webkit-transform: translateX(-166px)
}
}
.mini {
background-image: url("http://placehold.it/150x150");
position: absolute;
top: 10px;
left: 404px;
width: 166px;
height: 70px;
z-index: 7;
-webkit-animation: mini 2s linear;
}
<div class=mini></div>
this will keep the last frame of the animation after its done
animation-fill-mode: forwards;
#-webkit-keyframes mini {
from{
opacity:0;
}
to{
opacity:1;
}
from {
left:0px;
}
to{
left:404px;
}
}
.frame1 {
-webkit-animation: mini 2s normal forwards;
-moz-animation: mini 30s normal forwards;
-o-animation: mini 30s normal forwards;
animation: mini 2s normal forwards;
opacity:1;
}
.mini {
background-image: url("http://blog.grio.com/wp-content/uploads/2012/09/stackoverflow.png");
position: absolute;
top: 10px;
left: -404px;
width: 166px;
height: 70px;
z-index: 7;
}
<div class="frame1 mini">
</div>
hope this is what you are looking for

Animated progress bar with css

I want the progress bar to go from 0% width to 50% width in 2 seconds. This is my code so far:
<style>
#progressbar {
background-color: #000000;
border-radius: 8px;
padding: 3px;
width: 400px;
}
#progressbar div {
background-color: #0063C6;
height: 10px;
border-radius: 5px;
animation:loadbar 2s;
-webkit-animation:loadbar 2s;
}
#keyframes loadbar {
0% {
width: 0%;
}
100% {
width: 50%;
}
#-webkit-keyframes loadbar {
0% {
width: 0%;
}
100% {
width: 50%;
}
}
</style>
<div id="progressbar">
<div></div>
</div>
but when I open the page the width is 100% instead of 50%. what have I done wrong?
Your loadbar animation was not closed. The animation should work now. I've also added a forwards keyword to only play the animation once.
#progressbar {
background-color: black;
border-radius: 8px;
padding: 3px;
width: 400px;
}
#progressbar div {
background-color: #0063C6;
height: 10px;
border-radius: 5px;
animation:loadbar 2s normal forwards ease-in-out;
-webkit-animation:loadbar 2s normal forwards ease-in-out;
}
#keyframes loadbar {
0% {
width: 0%;
}
100% {
width: 100%;
}
}
#-webkit-keyframes loadbar {
0% {
width: 0%;
}
100% {
width: 100%;
}
}
Here's a Fiddle
#progressbar div {
background-color: #0063C6;
width: 50%;
height: 10px;
border-radius: 5px;
animation:loadbar 2s;
-webkit-animation:loadbar 2s;
}
#keyframes loadbar {
0% {
width: 0%;
}
100% {
width: 50%;
}
}
#-webkit-keyframes loadbar {
0% {
width: 0%;
}
100% {
width: 50%;
}
}
jsFiddle demo
Set the initial width to 0%
#progressbar div {
background-color: #0063C6;
height: 10px;
width:0%; /* ADD THIS <<< */
border-radius: 5px;
animation:loadbar 2s;
-webkit-animation:loadbar 2s;
-webkit-animation-fill-mode: forwards;
animation-fill-mode: forwards;
}
Additionally, I added in the following..
-webkit-animation-fill-mode: forwards;
animation-fill-mode: forwards;
If you want the animation to end in a forwards motion you need this... here is a demo demonstrating what would happen without it.. jsFiddle here
