html - Reorder row columns in repeating CSS grid/table -

when displaying multiple items in table/grid like-manner, possible css override elements order, without knowing number of "rows" in advance?

e.g. here standard table, , more compact alternative same data. had move html elements 2nd 1 (1, 4, 2, 3), otherwise 4th column got offset row.

.layout1 {    margin: 1em 0;    width: 400px;    display: grid;    grid-template-columns: auto auto auto max-content;    grid-row-gap: 0.2em;  }  .layout2 {    margin: 1em 0;    width: 200px;    display: grid;    grid-template-columns: auto auto max-content;  }  .layout2 .col1 {    margin-top: 0.2em;    grid-column: span 2;  }  .layout2 .col4 {    margin-top: 0.2em;    grid-row: span 2;  }  .layout2-5 .col2 {    grid-column: 1;  }  .layout2-5 .col3 {    grid-column: 2;  }  .layout2-5 .col4 {    grid-column: 3;  }  .col1, .col2, .col3, .col4 { padding: 0 1em; }  .col1 { background: #f99; }  .col2 { background: #9f9; }  .col3 { background: #99f; }  .col4 { background: #9ff; }

<div class="layout1">    <!--"row"-->    <div class="col1">1</div><div class="col2">2</div><div class="col3">3</div><div class="col4">4</div>    <!--"row"-->    <div class="col1">1</div><div class="col2">2</div><div class="col3">3</div><div class="col4">4</div>    <div class="col1">1</div><div class="col2">2</div><div class="col3">3</div><div class="col4">4</div>  </div>  <div class="layout2">    <!--"row"-->    <div class="col1">1</div><div class="col4">4</div><div class="col2">2</div><div class="col3">3</div>    <!--"row"-->    <div class="col1">1</div><div class="col4">4</div><div class="col2">2</div><div class="col3">3</div>    <div class="col1">1</div><div class="col4">4</div><div class="col2">2</div><div class="col3">3</div>  </div>   <div class="layout2 layout2-5">    <!--"row"-->    <div class="col1">1</div><div class="col2">2</div><div class="col3">3</div><div class="col4">4</div>    <!--"row"-->    <div class="col1">1</div><div class="col2">2</div><div class="col3">3</div><div class="col4">4</div>    <div class="col1">1</div><div class="col2">2</div><div class="col3">3</div><div class="col4">4</div>  </div>

what you're trying achieve not possibly grid display. possible way reorder columns without making use of rows utilise flexbox. using flex-direction: row-reverse automatically re-orders rows last first, , can 'overflow' reversal across rows flex-wrap: wrap-reverse.

it's possible completely modify order elements appear in, extending order property. in following example, i've added few :nth-of-type(4n) pseduo-selectors. note it's 4n because there 4 columns per 'row'.

.flex {    width: 342px;    display: flex;    flex-direction: row-reverse;    flex-wrap: wrap-reverse;  }    .flex > div:nth-of-type(4n) {    order: 2;  }    .flex > div:nth-of-type(4n + 1) {    order: 1;  }    .flex > div:nth-of-type(4n + 2) {    order: 3;  }    .flex > div:nth-of-type(4n + 3) {    order: 4;  }    .col1, .col2, .col3, .col4 {    width: 50px;    padding: 1em;    margin: 0.1em;    text-align: center;  }    .col1 {    background: #f99;  }    .col2 {    background: #9f9;  }    .col3 {    background: #99f;  }    .col4 {    background: #9ff;  }

<div class="flex">        <!--"row"-->    <div class="col1">1</div>    <div class="col2">2</div>    <div class="col3">3</div>    <div class="col4">4</div>        <!--"row"-->    <div class="col1">1</div>    <div class="col2">2</div>    <div class="col3">3</div>    <div class="col4">4</div>        <!--"row"-->    <div class="col1">1</div>    <div class="col2">2</div>    <div class="col3">3</div>    <div class="col4">4</div>      </div>

in above example, of .col3 elements wrapped first, of .col2 elements, of .col4 elements, of .col1 elements. feel free adapt suit; need change order values, , elements order property applied to. keep in mind order can go total number of elements; specify all 12 positions manually if desired:

.flex {    width: 342px;    display: flex;    flex-direction: row;    flex-wrap: wrap;  }    .flex > div:nth-of-type(1) {    order: 4;  }    .flex > div:nth-of-type(2) {    order: 2;  }    .flex > div:nth-of-type(3) {    order: 1;  }    .flex > div:nth-of-type(4) {    order: 3;  }    .flex > div:nth-of-type(5) {    order: 8;  }    .flex > div:nth-of-type(6) {    order: 6;  }    .flex > div:nth-of-type(7) {    order: 5;  }    .flex > div:nth-of-type(8) {    order: 7;  }    .flex > div:nth-of-type(9) {    order: 12;  }    .flex > div:nth-of-type(10) {    order: 10;  }    .flex > div:nth-of-type(11) {    order: 9;  }    .flex > div:nth-of-type(12) {    order: 11;  }    .col1, .col2, .col3, .col4 {    width: 50px;    padding: 1em;    margin: 0.1em;    text-align: center;  }    .col1 {    background: #f99;  }    .col2 {    background: #9f9;  }    .col3 {    background: #99f;  }    .col4 {    background: #9ff;  }

<div class="flex">        <!--"row"-->    <div class="col1">1</div>    <div class="col2">2</div>    <div class="col3">3</div>    <div class="col4">4</div>        <!--"row"-->    <div class="col1">1</div>    <div class="col2">2</div>    <div class="col3">3</div>    <div class="col4">4</div>        <!--"row"-->    <div class="col1">1</div>    <div class="col2">2</div>    <div class="col3">3</div>    <div class="col4">4</div>      </div>

hope helps! :)
