Fix gaps between inline-block children without changing markup

[mhulse]

Pretty cool way to remove the inline-block gaps:

/*csslint regex-selectors:false, known-properties:false, duplicate-properties:false*/

.pure-g {
    letter-spacing: -0.31em; /* Webkit: collapse white-space between units */
    *letter-spacing: normal; /* reset IE < 8 */
    *word-spacing: -0.43em; /* IE < 8: collapse white-space between units */
    text-rendering: optimizespeed; /* Webkit: fixes text-rendering: optimizeLegibility */

    /*
    Sets the font stack to fonts known to work properly with the above letter
    and word spacings. See: https://github.com/yahoo/pure/issues/41/

    The following font stack makes Pure Grids work on all known environments.

    * FreeSans: Ships with many Linux distros, including Ubuntu

    * Arimo: Ships with Chrome OS. Arimo has to be defined before Helvetica and
      Arial to get picked up by the browser, even though neither is available
      in Chrome OS.

    * Droid Sans: Ships with all versions of Android.

    * Helvetica, Arial, sans-serif: Common font stack on OS X and Windows.
    */
    font-family: FreeSans, Arimo, "Droid Sans", Helvetica, Arial, sans-serif;

    /* Use flexbox when possible to avoid `letter-spacing` side-effects. */
    display: flex;
    flex-flow: row wrap;

    /* Prevents distributing space between rows */
    align-content: flex-start;
}

/* IE10 display: -ms-flexbox (and display: flex in IE 11) does not work inside a table; fall back to block and rely on font hack */
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
    table .pure-g {
        display: block;
    }
}

/* Opera as of 12 on Windows needs word-spacing.
   The ".opera-only" selector is used to prevent actual prefocus styling
   and is not required in markup.
*/
.opera-only :-o-prefocus,
.pure-g {
    word-spacing: -0.43em;
}

.pure-u {
    display: inline-block;
    *display: inline; /* IE < 8: fake inline-block */
    zoom: 1;
    letter-spacing: normal;
    word-spacing: normal;
    vertical-align: top;
    text-rendering: auto;
}

/*
Resets the font family back to the OS/browser's default sans-serif font,
this the same font stack that Normalize.css sets for the `body`.
*/
.pure-g [class *= "pure-u"] {
    font-family: sans-serif;
}

Ignore the flexbox stuff.

Will need to do this too:

<style>
    /*
    When setting the primary font stack, apply it to the Pure grid units along
    with `html`, `button`, `input`, `select`, and `textarea`. Pure Grids use
    specific font stacks to ensure the greatest OS/browser compatibility.
    */
    html, button, input, select, textarea,
    .pure-g [class *= "pure-u"] {
        /* Set your content font stack here: */
        font-family: Georgia, Times, "Times New Roman", serif;
    }
    </style>
