How to use CSS grid to create 3x3 grid but place items in specific grid columns-CodePudding

I'm trying to create a layout that looks like this:

The blue blocks are divs. It's essentially a 3x3 grid but with gaps in the 3rd and 4th grid column.

How can I create a gap within CSS grid to achieve this layout? I've tried it with flexbox, but couldn't achieve the above, so hoping a grid layout is the answer.

Here's my code:

.container{
  border: 1px solid;
  display: grid; 
  grid-template-columns: 1fr 1fr 1fr; 
  grid-template-rows: 1fr 1fr; 
  gap: 0px 0px; 
  grid-template-areas: 
    ". . ."
    ". . ."; 
}

.item{
  border: 1px solid lightgrey;
  padding: 10px;
}

<div class="container">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
</div>

CSS grid allows you to choose which row and column an element will start in (and indeed, though not needed in your case, how many columns/rows it is to span).

This snippet gives the 3rd and 4th children of the wrapper specific grid positions.

.container {
  border: 1px solid;
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-template-rows: 1fr 1fr;
  grid-gap: 10px;
}

.item {
  border: 1px solid lightgrey;
  padding: 10px;
}

.item:nth-child(3) {
  grid-column: 2;
  grid-row: 2;
}

.item:nth-child(4) {
  grid-column: 3;
  grid-row: 2;
}

<div class="container">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
</div>

Note: just for a demo it has also introduced a non-zero grid-gap. The grid-area settings have been removed as not needed if the above method is followed.

A simplified version of the CSS grid solution with only the necessary code:

.container{
  border: 1px solid;
  display: grid; 
  grid-auto-columns: 1fr; 
  grid-auto-rows: 1fr;
  grid-gap:5px;
}

.item{
  border: 1px solid lightgrey;
  padding: 10px;
}

.item:nth-child(3) {
  grid-column:2;
}
.item:nth-child(4) {
  grid-column:3;
}

<div class="container">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
</div>

How about padding/margin?

.container {
  border: 1px solid #777;
  display: inline-grid; 
  grid-template-columns: 1fr 1fr 1fr; 
  grid-template-rows: 1fr 1fr; 
  gap: 0 0; 
  grid-template-areas: 
    ". . ."
    ". . ."; 
}

.item {
  border: 1px solid lightgrey;
  padding: 2px 0;
  width: 55px !important;
  height: 50px !important;
  margin: 1px !important;
  background: #1657c9;
  text-align: center;
  font-family: Arial, Helvetica, sans-serif;
  color: white;
}
.item-text {
  position: relative;
  top: 38%;
  margin: 0;
  font-size: normal;
}
.item-3, .item-4 {
  position: relative;
  left: 100%;
}

<div class="container">
  <div class="item item-1"><span class="item-text">1</span></div>
  <div class="item item-2"><span class="item-text">2</span></div><br>
  <div class="item item-3"><span class="item-text">3</span></div>
  <div class="item item-4"><span class="item-text">4</span></div>
</div>

You can try this: This is HTML:

<div class="parent">
<div class="div1"> </div>
<div class="div2"> </div>
<div class="div3"> </div>
<div class="div4"> </div>
</div>

and CSS

.parent {
      display: grid;
      grid-template-columns: repeat(5, 1fr);
      grid-template-rows: repeat(5, 1fr);
      grid-column-gap: 0px;
      grid-row-gap: 0px;
    }

    .div1 {
      grid-area: 1 / 1 / 2 / 2;
      background: blue;
      height: 3rem;
      margin: 1rem;
    }

    .div2 {
      grid-area: 1 / 2 / 2 / 3;
      background: blue;
      height: 3rem;
      margin: 1rem;
    }

    .div3 {
      grid-area: 2 / 2 / 3 / 3;
      background: blue;
      height: 3rem;
      margin: 1rem;
    }

    .div4 {
      grid-area: 2 / 3 / 3 / 4;
      background: blue;
      height: 3rem;
      margin: 1rem;
    }
