html - How do I create a 3x3 grid via CSS? -

-

given 9 divs 1 after another, want create grid 3x3 via css.

how do that?

.cell {    height: 50px;    width: 50px;    background-color: #999;    display: inline-block;  }    .cell:nth-child(3n) {    background-color: #f00;    /* property should use line break after element? */  }    /* doesn't work; @ least not in safari */  .cell:nth-child(3n)::after {    display: block;  }
<div class="grid">    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>  </div>

note: don't want float/clear solution. focus on css , not html restructure.

if add content: '\a'; white-space: pre; ::after output comes out ugly.

.cell {    height: 50px;    width: 50px;    background-color: #999;    display: inline-block;  }    .cell:nth-child(3n) {    background-color: #f00;    /* property should use line break after element? */  }    .cell:nth-child(3n)::after {    display: inline;    content: '\a';    white-space: pre;  }
<div class="grid">    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>  </div>

how go getting div in 3x3 row-column layout?

besides excellent answer @michael_b use flexbox, can use

  • css tables

    or

  • float:left

    both support old browsers such ie 8/9 , flexbox won't support.

note ie8 won't support nth-child supports first/last-child

option1 (css tables) : changes html, wrapping each 3 cells in row.

.grid {    display: table;    border-spacing: 5px  }  .row {    display: table-row  }  .cell {    width: 50px;    height: 50px;    background: grey;    display: table-cell;  }  .row div:last-child {    background: red  }
<div class="grid">    <div class="row">      <div class="cell"></div>      <div class="cell"></div>      <div class="cell"></div>    </div>    <div class="row">      <div class="cell"></div>      <div class="cell"></div>      <div class="cell"></div>    </div>    <div class="row">      <div class="cell"></div>      <div class="cell"></div>      <div class="cell"></div>    </div>  </div>

update

option2 (float:left): no changes html, using clear:left @ each (4th)n item.

.cell {    width: 50px;    height: 50px;    background: grey;    float: left;    margin: 5px  }  .cell:first-child + div+ div,  .cell:first-child + div+ div + div + div + div,  .cell:first-child + div+ div + div + div + div + div + div + div {    background: red  }  .cell:first-child + div+ div + div,  .cell:first-child + div+ div + div + div + div + div,  .cell:first-child + div+ div + div + div + div + div + div + div + div {    clear: left  }
<div class="grid">    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>    <div class="cell"></div>  </div>
