I'm searching for a solution to my problem with CSS grid. The problem I have right now is I have a grid with 4 column and 10 boxes which fills a column row cell like so: enter image description here However, I would like the remaining two boxes to auto span to fit the entire width like this: enter image description here (box 9 and box 10). Although I've achieved it here, I don't want to manually have to do it. I'd like the grid to automatically be able to do it. Is this achievable?

html {

.grid {

    display:grid;
    grid-template-columns: 1fr 1fr 1fr 1fr;

.grid .box {

  text-align: center;

/* .grid .box:nth-child(9) {
   grid-column: span 2;
}
.grid .box:nth-child(10) {
   grid-column: span 2;
} */
@media (max-width:768px){
    .grid {
        grid-template-columns: 1fr 1fr 1fr 1fr;
    }
}
</style>
<body>


    <div class="grid">

  • Not possible with CSS-Grid, you need flexbox.

  • What do you mean by to auto span? Your picture is possible with grid, just it's not clear what 'to auto span' is.

  • For box 9 and 10 in the first image, I would like that to evenly occupy the third row like the last picture.

You could do this with flex-box using flex-grow and a calc for the width. For the child elements divisible by 4 the calc width will dynamically fill those in using the calculated width width: calc(25% - 1em). For the left over elements not divisible by four, flex-grow: 1 will ensure they fill up the remaining space.

.parent {
  display: flex;
  flex-wrap: wrap;
  gap: 1em;
}

.child {
  display: flex;
  justify-content: center;
  flex-grow: 1;
  width: calc(25% - 1em);
  background-color: red;
  height: 2em;
}
<div class="parent">
  <div class="child">Box 1</div>
  <div class="child">Box 2</div>
  <div class="child">Box 3</div>
  <div class="child">Box 4</div>
  <div class="child">Box 5</div>
  <div class="child">Box 6</div>
  <div class="child">Box 7</div>
  <div class="child">Box 8</div>
  <div class="child">Box 9</div>
</div>
<br><br>
<div class="parent">
  <div class="child">Box 1</div>
  <div class="child">Box 2</div>
  <div class="child">Box 3</div>
  <div class="child">Box 4</div>
  <div class="child">Box 5</div>
  <div class="child">Box 6</div>
  <div class="child">Box 7</div>
  <div class="child">Box 8</div>
  <div class="child">Box 9</div>

</div>

  • You're welcome... Flex is more intuitively flexible, no pun intended, for dynamic layouts than grid.

Actually you were very close:)

.grid {
    width:100%;
    height:200px;
    display:grid;
    grid-template-columns: 1fr 1fr 1fr 1fr;
    gap:10px;
  
}
.grid .box {
   
  width:100%;
  height:100%;
  text-align: center;
  
    background-color: red;
   
}

.grid .box:nth-child(9) {
   grid-column: 1/span 2;
}
.grid .box:nth-child(10) {
   grid-column: 3/span 2;
} 
@media screen (max-width:768px){
    .grid {
        grid-template-columns: 1fr 1fr 1fr 1fr;
    }
}
<div class="grid">

        <div class="box">Box 1</div>
        <div class="box">Box 2</div>
        <div class="box">Box 3</div>
        <div class="box">Box 4</div>
        <div class="box">Box 5</div>
        <div class="box">Box 6</div>
        <div class="box">Box 7</div>
        <div class="box">Box 8</div>
        <div class="box">Box 9</div>
        <div class="box">Box 10</div>
      
    </div>

    I already know how to do it manually, I wanted to know whether it was possible for CSS grid to be able to do it automatically.
