Two inline-block, width 50% elements wrap to second line [duplicate]

This question already has answers here: Ignore whitespace in HTML [duplicate] 开发者_开发百科 (12 answers) Closed 8 years ago.

I would like to have two columns of 50% width space, and avoid floats. So i thought using display:inline-block.

When the elements add to 99% width (eg 50%, 49%, http://jsfiddle.net/XCDsu/2/ ) it works as expected.

When using 100% width (eg 50%, 50%, http://jsfiddle.net/XCDsu/3/ ) the second column breaks to the second line.

Why is that?

It is because display:inline-block takes into account white-space in the html. If you remove the white-space between the div's it works as expected. Live Example: http://jsfiddle.net/XCDsu/4/

<div id="col1">content</div><div id="col2">content</div>

You can remove the whitespaces via css using white-space so you can keep your pretty HTML layout. Don't forget to set the white-space back to normal again if you want your text to wrap inside the columns.

Tested in IE9, Chrome 18, FF 12

.container { white-space: nowrap; }
.column { display: inline-block; width: 50%; white-space: normal; }

<div class="container">
  <div class="column">text that can wrap</div>
  <div class="column">text that can wrap</div>
</div>

NOTE: In 2016, you can probably use flexbox to solve this problem easier.

This method works correctly IE7+ and all major browsers, it's been tried and tested in a number of complex viewport-based web applications.

<style>
    .container {
        font-size: 0;
    }

    .ie7 .column {
        font-size: 16px; 
        display: inline; 
        zoom: 1;
    }

    .ie8 .column {
        font-size:16px;
    }

    .ie9_and_newer .column { 
        display: inline-block; 
        width: 50%; 
        font-size: 1rem;
    }
</style>

<div class="container">
    <div class="column">text that can wrap</div>
    <div class="column">text that can wrap</div>
</div>

The only downside to this method for IE7/8, is relying on body {font-size:??px} as basis for em/%-based font-sizing.

IE7/IE8 specific CSS could be served using IE's Conditional comments

inline and inline-block elements are affected by whitespace in the HTML.

The simplest way to fix your problem is to remove the whitespace between </div> and <div id="col2">, see: http://jsfiddle.net/XCDsu/15/

There are other possible solutions, see: bikeshedding CSS3 property alternative?

I continued to have this problem in ie7 when the browser was at certain widths. Turns out older browsers round the pixel value up if the percentage result isn't a whole number. To solve this you can try setting

overflow: hidden;

on the last element (or all of them).
