html - Creating 2 div under each other on CSS

Question

I need to split my 2 block, on 4 blocks. I mean calibrate,connect,train,analyze needs to be separately, but in my code calibrate and connect are in one block, and train and analyze the same in another block with boxshadow. I splited them, but in this case my animation does not work correctly. How can I split them without losing my animation and bring them closely to image?

.div-wrap {
  display: flex;
  align-items: center;
  flex-flow: column nowrap;
  justify-content: space-between;
  text-align: center;
}

:root {
  --time: 24;
}

.div-txt p.label {
  color: #0065de;
  font: bold 16px 'Arial';
  animation-duration: calc(var(--time) * 1s);
  animation-iteration-count: infinite;
  animation-name: color-change;
}

.div-txt:nth-child(1) p.label:nth-child(2) {
  animation-delay: 0s;
}

.div-txt:nth-child(1) p.label:nth-child(5) {
  animation-delay: calc(var(--time) / 4 * 1s);
}

.div-txt:nth-child(3) p.label:nth-child(2) {
  animation-delay: calc(var(--time) / 2 * 1s);
}

.div-txt:nth-child(3) p.label:nth-child(5) {
  animation-delay: calc(var(--time) / 1.33 * 1s);
}

.div-img {
  position: relative;
  height: 600px;
  width: 600px;
  /*  border: 2px solid #ccc;*/

.div-img img:nth-child(1) {

Answer 1

First of all, you should start at preparing correct layout structure.
As you mentioned we need [ SIDEBAR ] [ ANIMATION ] [ SIDEBAR ] all inline.

So let's try.

.container > div {
  display: flex;
  justify-content: center;
  align-items: center;
  font-size: 1.5em;
  color: #ffeead;
}

html, body {
  box-sizing: border-box;
  background-color: #ffeead;
  height: 100%;
  padding: 10px;
  margin: 0px;
}

* {
    box-sizing: border-box;
}

.container > div:nth-child(1n) {
  background-color: #96ceb4;	
}

.container > div:nth-child(3n) {
  background-color: #88d8b0;
}

.container > div:nth-child(2n) {
  background-color: #ff6f69;
}


.container {
    height: 100%;
    display: grid;
    grid-template-columns: minmax(200px, 1fr) repeat(4, minmax(200px, 1fr)) minmax(200px, 1fr);
    grid-template-areas: 's1 a a a a s2'
}

.animation {
    grid-area: a;
}

.block1, .block2 {
    align-items: center;
    justify-content: center;
    background: #ffad3d;
    display: flex;
    flex: 1;
    height: 100%;
    margin: 0 5px;
    padding: 10px;
}

.left-sidebar, .right-sidebar {
    padding: 10px;
}

.left-sidebar {
    grid-area: s1;
}

.right-sidebar {
    grid-area: s2;
}

<div class='container'>
    <div class='left-sidebar'>
        <div class='block1'>block 1</div>
        <div class='block1'>block 2</div>
    </div>
    <div class='animation'>ANIMATION</div>
    <div class='right-sidebar'>
        <div class='block1'>block 1</div>
        <div class='block1'>block 2</div>
    </div>
</div>
