Is it possible to make a spinner with pure CSS without Javascript?

<div class="main spinner"> O que é Lorem Ipsum?
Lorem Ipsum é simplesmente uma simulação de texto da indústria tipográfica e de impressos, e vem sendo utilizado desde o século XVI, quando um impressor desconhecido pegou uma bandeja de tipos e os embaralhou para fazer um livro de modelos de tipos. Lorem Ipsum sobreviveu não só a cinco séculos, como também ao salto para a editoração eletrônica, permanecendo essencialmente inalterado. Se popularizou na década de 60, quando a Letraset lançou decalques contendo passagens de Lorem Ipsum, e mais recentemente quando passou a ser integrado a softwares de editoração eletrônica como Aldus PageMaker </div>

Another technique for doing this loaders or spinners is to use Animated SVG.

First you have to make it clear that you can, for example, have an SVG where you will animate your vectors using CSS properties like transform , opacite , etc, all through CSS. Or you can animate everything directly within SVG using its native tags like <animate> , <set> and <animateMotion> for example.

Here is an example of 100% animation made with CSS using @keyframes, but animating the stroke-dashoffset property of SVG. Hint: In that other response you have more dentalhes on stroke-dasharray and strok-dashoffset to animate the "outline" of an HTML element Partially paint the border in css

Notice that I left one Triangle with the animation, and the other I just leave the SVG simple, without the CSS animation.

html, body {
  background-color: #f3f3f3;
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100%;
}

#triangle {
  -webkit-transform-origin: 50% 65%;
          transform-origin: 50% 65%;
}

#triangle polygon {
  stroke-dasharray: 17;
  -webkit-animation: dash 2.5s cubic-bezier(0.35, 0.04, 0.63, 0.95) infinite;
          animation: dash 2.5s cubic-bezier(0.35, 0.04, 0.63, 0.95) infinite;
}

@-webkit-keyframes dash {
  to {
    stroke-dashoffset: 136;
  }
}

@keyframes dash {
  to {
    stroke-dashoffset: 136;
  }
}
@-webkit-keyframes rotate {
  100% {
    -webkit-transform: rotate(360deg);
            transform: rotate(360deg);
  }
}
@keyframes rotate {
  100% {
    -webkit-transform: rotate(360deg);
            transform: rotate(360deg);
  }
}

<svg id="triangle" width="100px" height="100px" viewBox="-3 -4 39 39">
  <polygon fill="#EFEFEF" stroke="#333333" stroke-width="1" points="16,0 32,32 0,32"></polygon>
</svg>

<svg id="" width="100px" height="100px" viewBox="-3 -4 39 39">
  <polygon fill="#EFEFEF" stroke="#333333" stroke-width="1" points="16,0 32,32 0,32"></polygon>
</svg>

Native Animation with SVG

Here is a guide that can help you if you want to animate everything directly within SVG link

Example of SVG animated natively, notice that there is no CSS and everything was animated inside the SVG itself:

<svg version="1.1" width="320" height="320" viewBox="0 0 320 320" fill="none" stroke="#000" stroke-linecap="round"

Here's the official W3C documentation on SVG animation link

OBS:

You do not need any extra features to animate SVGs but if you want there are software and APIs that help you to animate and export your animated SVG! One platform option to animate your SVG online is the link or the link

There are also JS frameworks to animate SVGs such as link or link and the most famous TweenMax GSAP link

The strategy we use is to take a square, round the edges with border-radius 50%, paint the edges with a transparent color or equal to the background, then you paint only a piece of the border of the color you want and then place this bit of edge to rotate with an animation based on the transform rotate. :)

.load-spin:before {
  content: '';
  width: 40px;
  height: 40px;
  border: 4px solid white;
  border-top-color: red;
  -webkit-animation: spin 1s infinite linear;
  left: calc(50% - 1.5rem);
  position: absolute;
  border-radius: 50%;
}
@-webkit-keyframes spin {
  0%  {-webkit-transform: rotate(0deg);}
  100% {-webkit-transform: rotate(360deg);}   
}

<div class="load-spin"></div>

There are several ways you can do it, here are four different types of spinner I've removed from the following sources:

Example 1:

/* Spinner CSS */
@keyframes spinner {
  to {transform: rotate(360deg);}
}
.spinner:before {
  content: '';
  box-sizing: border-box;
  position: absolute;
  top: 20%;
  left: 20%;
  width: 20px;
  height: 20px;
  margin-top: -10px;
  margin-left: -10px;
  border-radius: 50%;
  border: 2px solid #ccc;
  border-top-color: #333;
  animation: spinner .6s linear infinite;
}

<div class="spinner"></div>

Example 2:

.spinner {
  margin: 100px auto;
  width: 50px;
  height: 40px;
  text-align: center;
  font-size: 10px;
}

.spinner > div {
  background-color: #333;
  height: 100%;
  width: 6px;
  display: inline-block;
  
  -webkit-animation: sk-stretchdelay 1.2s infinite ease-in-out;
  animation: sk-stretchdelay 1.2s infinite ease-in-out;
}

.spinner .rect2 {
  -webkit-animation-delay: -1.1s;
  animation-delay: -1.1s;
}

.spinner .rect3 {
  -webkit-animation-delay: -1.0s;
  animation-delay: -1.0s;
}

.spinner .rect4 {
  -webkit-animation-delay: -0.9s;
  animation-delay: -0.9s;
}

.spinner .rect5 {
  -webkit-animation-delay: -0.8s;
  animation-delay: -0.8s;
}

@-webkit-keyframes sk-stretchdelay {
  0%, 40%, 100% { -webkit-transform: scaleY(0.4) }  
  20% { -webkit-transform: scaleY(1.0) }
}

@keyframes sk-stretchdelay {
  0%, 40%, 100% { 
    transform: scaleY(0.4);
    -webkit-transform: scaleY(0.4);
  }  20% { 
    transform: scaleY(1.0);
    -webkit-transform: scaleY(1.0);
  }
}

<div class="spinner">
  <div class="rect1"></div>
  <div class="rect2"></div>
  <div class="rect3"></div>
  <div class="rect4"></div>
  <div class="rect5"></div>
</div>

Example 3:

.spinner {
  margin: 100px auto 0;
  width: 70px;
  text-align: center;
}

.spinner > div {
  width: 18px;
  height: 18px;
  background-color: #333;

  border-radius: 100%;
  display: inline-block;
  -webkit-animation: sk-bouncedelay 1.4s infinite ease-in-out both;
  animation: sk-bouncedelay 1.4s infinite ease-in-out both;
}

.spinner .bounce1 {
  -webkit-animation-delay: -0.32s;
  animation-delay: -0.32s;
}

.spinner .bounce2 {
  -webkit-animation-delay: -0.16s;
  animation-delay: -0.16s;
}

@-webkit-keyframes sk-bouncedelay {
  0%, 80%, 100% { -webkit-transform: scale(0) }
  40% { -webkit-transform: scale(1.0) }
}

@keyframes sk-bouncedelay {
  0%, 80%, 100% { 
    -webkit-transform: scale(0);
    transform: scale(0);
  } 40% { 
    -webkit-transform: scale(1.0);
    transform: scale(1.0);
  }
}

<div class="spinner">
  <div class="bounce1"></div>
  <div class="bounce2"></div>
  <div class="bounce3"></div>
</div>

Example 4:

.spinner {
  box-sizing: border-box;
  height: 60px;
  width: 60px;
  margin: 80px;
  border: 0px solid #27ae60;
  border-radius: 50%;
  box-shadow: 0 -20px 0 24px #27ae60 inset;
  animation: rotate 1s infinite linear;
}

@keyframes rotate {
  0% {
    transform: rotate(0deg);
  }
  100% {
    transform: rotate(360deg);
  }
}

<div class="spinner"></div>
