Justify divs with CSS to fill width of parent container [duplicate]

Answer 1

Using CSS3 this is now super easy.

UPDATE

Added MS IE support (believe in it or not...). I'm not pretty sure about the FF stuff because Mozilla changed something. I have not so much time. So if someone could maybe correct me...

UPDATE II

Moved code to snippet

.container {
  border: 1px solid black;
  display: -webkit-box;
  -webkit-box-pack: justify;
  -webkit-box-align: center;
  display: -moz-box;
  -moz-box-pack: justify;
  -moz-box-align: center;
  display: -ms-flexbox;
  -ms-flex-pack: justify;
  -ms-flex-align: center;
  display: box;
  box-pack: justify;
  box-align: center;
}
.child {
  background-color: red;
}

<div class="container">
  <div class="child">
    Some Content
  </div>
  <div class="child">
    Some Content
  </div>
  <div class="child">
    Some Content
  </div>
</div>

Answer 2

You can do this with CSS if specify all dimensions in percents (ie. width, margin, padding).

Or if you want a specific margin or padding, you can use jQuery

$(window).resize(function() {
  var $columns = $('.column'),
      numberOfColumns = $columns.length,               
      marginAndPadding = 0,
      newColumnWidth = ($('#container').width() / numberOfColumns) - marginAndPadding,
      newColumnWidthString = newColumnWidth.toString() + "px";

  $columns.css('width', newColumnWidthString);
}).resize();

Check out thirtydot's answer in this thread for a pure CSS/HTML solution without JavaScript that works in all browsers including IE 6.

Fluid width with equally spaced DIVs

http://jsfiddle.net/thirtydot/EDp8R/

HTML:

<div id="container">
    <div class="box1"></div>
    <div class="box2"></div>
    <div class="box3"></div>
    <div class="box4"></div>
    <span class="stretch"></span>
</div>​

CSS:

#container {
    border: 2px dashed #444;
    height: 125px;

    text-align: justify;
    -ms-text-justify: distribute-all-lines;
    text-justify: distribute-all-lines;

    /* just for demo */
    min-width: 612px;
}

.box1, .box2, .box3, .box4 {
    width: 150px;
    height: 125px;
    vertical-align: top;
    display: inline-block;
    *display: inline;
    zoom: 1
}
.stretch {
    width: 100%;
    display: inline-block;
    font-size: 0;
    line-height: 0
}

.box1, .box3 {
    background: #ccc
}
.box2, .box4 {
    background: #0ff
}
