Share 10 Loading effects implemented in pure CSS

When we encounter loading, it is either built-in in the UI framework or Baidu, and then CV is added to the project? However, when you implement it yourself, you will have no idea. In this article, I will share with you 10 Loading effects implemented in pure CSS. I hope it will be helpful to you!

See ten Loading effects introduced by T. Afif on Twitter. As shown above.

Yeah, it’s great, very practical, so I recorded it.

To ensure normal operation, we first stipulate:

* {
  box-sizing: border-box;
}

1. Smooth loading

<div class="progress-1"></div>

.progress-1 {
  width:120px;
  height:20px;
  background:
   linear-gradient(#000 0 0) 0/0% no-repeat
   #ddd;
  animation:p1 2s infinite linear;
}
@keyframes p1 {
    100% {background-size:100%}
}

• linear-gradient(#000 0 0) You can understand it as linear-gradient(#000 0 100%). If you are not familiar with it yet, copy linear-gradient(#000 0 50%, #f00 50% 0), replace the original part and run it. If you feel linear-gradient(#000 0 0) is awkward, just write #000.

• ##0/0% isbackground-position: 0;/background-size : 0;Abbreviation of .

2. Load step by step

<div class="progress-2"></div>

.progress-2 {
  width:120px;
  height:20px;
  border-radius: 20px;
  background:
   linear-gradient(orange 0 0) 0/0% no-repeat
   lightblue;
  animation:p2 2s infinite steps(10);
}
@keyframes p2 {
    100% {background-size:110%}
}

• steps(10) Yes The abbreviation of step(10, end) indicates that there is no one at the beginning, so there is point 2

• ##100% {background-size:110%}

  Add one more percentage of step. The above step is 10, so it is 100% ( 1/10)*100% = 110%

3. Stripe loading

<div class="progress-3"></div>

.progress-3 {
  width:120px;
  height:20px;
  border-radius: 20px;
  background:
   repeating-linear-gradient(135deg,#f03355 0 10px,#ffa516 0 20px) 0/0% no-repeat,
   repeating-linear-gradient(135deg,#ddd 0 10px,#eee 0 20px) 0/100%;
  animation:p3 2s infinite;
}
@keyframes p3 {
    100% {background-size:100%}
}

repeating- linear-gradient(135deg,#ddd 0 10px,#eee 0 20px) 0/100%;

Draw gray zebra stripes,repeating-linear-gradient(135deg,#f03355 0 10px,#ffa516 0 20px) 0/0% no-repeat is the stripe of the progress bar loading. 4. Dotted line loading

<div class="progress-4"></div>

.progress-4 {
  width:120px;
  height:20px;
  -webkit-mask:linear-gradient(90deg,#000 70%,#0000 0) 0/20%;
  background:
   linear-gradient(#000 0 0) 0/0% no-repeat
   #ddd;
  animation:p4 2s infinite steps(6);
}
@keyframes p4 {
    100% {background-size:120%}
}

-webkit-mask

has the default value repeat, otherwise it will be masked There won't be five. 5. Battery loading

<div class="progress-5"></div>

.progress-5 {
  width:80px;
  height:40px;
  border:2px solid #000;
  padding:3px;
  background: 
    repeating-linear-gradient(90deg,#000 0 10px,#0000 0 16px) 
    0/0% no-repeat content-box content-box;
  position: relative;
  animation:p5 2s infinite steps(6);
}
.progress-5::before {
  content:"";
  position: absolute;
  top: 50%;
  left:100%;
  transform: translateY(-50%);
  width:10px;
  height: 10px;
  border: 2px solid #000;
}
@keyframes p5 {
    100% {background-size:120%}
}

The original author implemented the

.progress-5::before

pseudo-element as follows: <pre class='brush:php;toolbar:false;'>.progress-5::before { content:&quot;&quot;; position: absolute; top:-2px; bottom:-2px; left:100%; width:10px; background: linear-gradient( #0000 calc(50% - 7px),#000 0 calc(50% - 5px), #0000 0 calc(50% + 5px),#000 0 calc(50% + 7px),#0000 0) left /100% 100%, linear-gradient(#000 calc(50% - 5px),#0000 0 calc(50% + 5px),#000 0) left /2px 100%, linear-gradient(#0000 calc(50% - 5px),#000 0 calc(50% + 5px),#0000 0) right/2px 100%; background-repeat:no-repeat; }</pre>

#0000 is transparent, equally transparent

6. Inline loading

The name is a bit inappropriate, but it’s not important. Readers can see the picture naturally. understand.

<div class="progress-6"></div>

.progress-6 {
  width:120px;
  height:22px;
  border-radius: 20px;
  color: #514b82;
  border:2px solid;
  position: relative;
}
.progress-6::before {
  content:"";
  position: absolute;
  margin:2px;
  inset:0 100% 0 0;
  border-radius: inherit;
  background: #514b82;
  animation:p6 2s infinite;
}
@keyframes p6 {
    100% {inset:0}
}

inset:0 100% 0 0;

The right side is indented 100%, so in keyframes## The # part requires setting inset to 0. 7. Bead chain loading

<div class="progress-7"></div>

.progress-7 {
  width:120px;
  height:24px;
  -webkit-mask:
    radial-gradient(circle closest-side,#000 94%,#0000) 0 0/25% 100%,
    linear-gradient(#000 0 0) center/calc(100% - 12px) calc(100% - 12px) no-repeat;
  background:
   linear-gradient(#25b09b 0 0) 0/0% no-repeat
   #ddd;
  animation:p7 2s infinite linear;
}
@keyframes p7 {
    100% {background-size:100%}
}

mask-webkit-mask

medium

radial-gradient is Divide the width into four equal parts and draw a circle with the smallest closest-side side as the diameter for each part. 8. Zebra crossing loading

<div class="progress-8"></div>

.progress-8 {
  width:60px;
  height:60px;
  border-radius: 50%;
  -webkit-mask:linear-gradient(0deg,#000 55%,#0000 0) bottom/100% 18.18%;
  background:
   linear-gradient(#f03355 0 0) bottom/100% 0% no-repeat
   #ddd;
  animation:p8 2s infinite steps(7);
}
@keyframes p8 {
    100% {background-size:100% 115%}
}

Adjust the angle drawn by linear-gradient

and add a mask.

9. Water column loading

<div class="progress-9"></div>

.progress-9 {    
  --r1: 154%;
  --r2: 68.5%;
  width:60px;
  height:60px;
  border-radius: 50%; 
  background:
    radial-gradient(var(--r1) var(--r2) at top ,#0000 79.5%,#269af2 80%) center left,
    radial-gradient(var(--r1) var(--r2) at bottom,#269af2 79.5%,#0000 80%) center center,
    radial-gradient(var(--r1) var(--r2) at top ,#0000 79.5%,#269af2 80%) center right,
    #ccc;
  background-size: 50.5% 220%;
  background-position: -100% 0%,0% 0%,100% 0%;
  background-repeat:no-repeat;
  animation:p9 2s infinite linear;
}
@keyframes p9 {
    33%  {background-position:    0% 33% ,100% 33% ,200% 33% }
    66%  {background-position: -100%  66%,0%   66% ,100% 66% }
    100% {background-position:    0% 100%,100% 100%,200% 100%}
}

radial-gradient

Draw the fluctuations of the horizontal plane, just three circles.

var(--r1) Directly call the defined attribute value. Skillget ...10. Signal loading

<div class="progress-10"></div>

.progress-10 {
  width:120px;
  height:60px;
  border-radius:200px 200px 0 0;
  -webkit-mask:repeating-radial-gradient(farthest-side at bottom ,#0000 0,#000 1px 12%,#0000 calc(12% + 1px) 20%);
  background:
   radial-gradient(farthest-side at bottom,#514b82 0 95%,#0000 0) bottom/0% 0% no-repeat
   #ddd;
  animation:p10 2s infinite steps(6);
}
@keyframes p10 {
    100% {background-size:120% 120%}
}

Use the repeating-radial-gradient

method Draw a circular mask.

radial-gradient Fill the circular gradient from the bottom upward. Uha, after seeing so many cool operations, have you lost your skills?
