Make table cells square

Question

How to ensure that each cell of table should become square without using fixed sizes? And be responsive when they change width.

table {
  width: 90%;
}
td {
  width: 30%;
}
tr {
  /** what should go here? **/
}

<table>
  <tr>
    <td>1</td>
    <td>2</td>
    <td>3</td>
  </tr>
  <tr>
    <td>4</td>
    <td>5</td>
    <td>6</td>
  </tr>
  <tr>
    <td>7</td>
    <td>8</td>
    <td>9</td>
  </tr>
<table>

New answer :

To make the table cells square, you can use the aspect-ratio property on a div inside the td element. Like this :

table {
  width: 90%;
}
td {
  width: 33.33%;
  position: relative;
}
td .content {
  aspect-ratio: 1 / 1 ;
  background: gold;
}

<table>
  <tr>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
  </tr>
  <tr>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
  </tr>
  <tr>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
  </tr>
</table>

Previous answer :

You can use the technique described in: Grid of responsive squares.

Adapted to your usecase with a table and square table cells, it would look like this:

table {
  width: 90%;
}
td {
  width: 33.33%;
  position: relative;
}
td:after {
  content: '';
  display: block;
  margin-top: 100%;
}
td .content {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background: gold;
}

<table>
  <tr>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
  </tr>
  <tr>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
  </tr>
  <tr>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
    <td><div class="content">1</div></td>
  </tr>
</table>

Could both downvoters explain the reason pls I'm ok with that but it isn't very constructive without explanation.

this solution doesn't work on android <4.3 stock browsers. Still cool though :)

how to vertical-align:middle the content ?

web-tiki Over a year ago

@BradKent there is a technique described here : stackoverflow.com/a/20457076/1811992 (see 3.Centering the content). You can also have a look at this stackoverflow.com/questions/8865458/…

Before align the text firstly you have to add " width: 100%; height: 100%;" to the "td .content {...}" and after you can align the text simple

Here is my code: http://jsfiddle.net/vRLBY/1/

The key is to use:

td { width: 33%; padding-bottom: 33%; height: 0; }
td div { position: absolute }

because padding-bottom is defined in terms of the width. More information: http://absolide.tumblr.com/post/7317210512/full-css-fluid-squares

Note: Previously I posted a not working code (see here). Thanks to @web-tiki for reporting the bug ;-)

well this has a pretty wierd effect in this fiddle : jsfiddle.net/webtiki/cM3yb

Stephan Kulla Over a year ago

@web-tiki: For we it worked fine in fiddle. Can you describe the weired effect you are seeing?

Stephan Kulla Over a year ago

Never used jFiddle before, so I cannot say when it looks okay and when weird... ;-) I would suggest, that you have to delete the body { ... } from the CSS....

web-tiki Over a year ago

well fiddle is very handy, you can edit it and save it to show us your technique working. It basicaly is like a webpage taht everyone can edit, save and share...

web-tiki Over a year ago

@tampis I just checked with firefox and it is better but the tds aren't square. I'll make a screenshot to show you.

If someone's looking for a solution that does not require fixed width property (even in percentage), here's what I came up with based on above answers and the link from approved answer:

td {
    height: 0;

    &:after, &:before {
        content: '';

        display: block;
        padding-bottom: calc(50% - 0.5em);
    }
}

It's kinda lame but it kills two birds with one stone:

does the trick
makes content aligned vertically

this is Sass/Less code rather than plain css

For me the solution is to divide 100% per number of cells you have.

For example, if you have 7 cells:

100% / 7 = 14.28%

So 14.28% is the size for each cell.

<td style="height=14.28%; width=14.28%;" >...</td>
