AngularJS - シンプルな六角グリッド

##経緯

• あるWebデザイナーのサイトの綺麗なレスポンシブ六角グリッドレイアウトが気に入ったので、勉強のために関連するCSSを抽出してみた。
• 作者：Rachid Mrad氏（ http://www.rachidmrad.com/#/portfolio ）

##依存性

• AngularJS, ngAnimate
• Bootstrap

HTML

<div class="wrapper">

  <section class="hex-grid">

    <div
      ng-repeat="item in app.items"
      class="grid-item repeat-animation">

      <div class="inner">
        <div
          class="inner-inner"
          ng-style="{ 'background-image': 'url({{ item.imgSrc }})' }">

          <a
            href=""
            class="grid-info">

            <div class ="inner-text">
              <div class="inner-text-inner">

                <h2>{{ item.name }}</h2>
                <p>{{ item.desc }}</p>

              </div><!-- /.inner-text-inner -->
            </div><!-- /.inner-text -->
          </a><!-- /.grid-info -->
        </div><!-- /.inner-inner -->
      </div><!-- /.inner -->
