基于 css 的六边形内部的图像

Question

我使用的 James Tauber's hexagon tutorial to create a honeycomb-styled navigation. I have the orientation that I want, but I am having trouble figuring out how to add images to the inside of the hexagons. Is the code in the jsfiddle 未针对将图像放入六边形进行优化，还是我没有看到什么？

我意识到关于将图像放入六边形内还有其他问题，但 none 确实帮助了我。

不胜感激。

HTML:

.hex {
      float: left;
      margin-right: -26px;
      margin-bottom: -50px;
    }
    .hex .left {
      float: left;
      width: 0;
      border-right: 30px solid #444;
      border-top: 52px solid transparent;
      border-bottom: 52px solid transparent;
    }
    .hex .middle {
      float: left;
      width: 60px;
      height: 104px;
      background: #444;
    }
    .hex .right {
      float: left;
      width: 0;
      border-left: 30px solid #444;
      border-top: 52px solid transparent;
      border-bottom: 52px solid transparent;
    }
    .hex-row {
      clear: left;
    }
    .hex.even {

Answer 1

按照此 CSS 的设置方式，您可以在中心制作背景图片，但左右两侧仍然会有灰色三角形。 background-image: 的代码有点复杂，但请查看我的 fiddle 以了解其工作原理 http://jsfiddle.net/z9Lo0gmu/

这是一个更复杂的六边形网格示例：Responsive grid of hexagons

Answer 2

好吧，好吧，我不能用你制作六边形的方法来做，因为它只是一堆孔 - 一个边界（background-image 不适用于边界）。但是我找到了另一种方法，使用 @geoffrey_crofte's solution on codepen.

首先，这是带有工作示例的 JSFiddle。

这是更新后的代码。

HTML:

<div id="wrap">
<div class="hex-row">
    <a href="http://www.google.ca" class='hexaHolder'>
        <div class="hexa">
            <div class="hex1">
                <div class="hex2">
                    <img src="http://farm3.staticflickr.com/2788/4392569951_8bcec3b3ed_z.jpg?zz=1" alt="" />
                </div>
            </div>
        </div>
    </a>
    <a href="http://www.google.ca" class='hexaHolder even'>
        <div class="hexa">
            <div class="hex1">
                <div class="hex2">
                    <img src="http://farm3.staticflickr.com/2441/3657346647_a11111ed39_z.jpg?zz=1" alt="" />
                </div>
            </div>
        </div>
    </a>
    <a href="http://www.google.ca" class='hexaHolder'>
        <div class="hexa">
            <div class="hex1">
                <div class="hex2">
                    <img src="http://farm3.staticflickr.com/2178/3531465579_8bff044e9b_z.jpg?zz=1" alt="" />
                </div>
            </div>
        </div>
    </a>
    <a href="http://www.google.ca" class='hexaHolder even'>
        <div class="hexa">
            <div class="hex1">
                <div class="hex2">
                    <img     src="http://farm3.staticflickr.com/2441/3657346647_a11111ed39_z.jpg?zz=1" alt="" />
                </div>
            </div>
        </div>
    </a>
    <a href="http://www.google.ca" class='hexaHolder'>
        <div class="hexa">
            <div class="hex1">
                <div class="hex2">
                    <img src="http://farm4.staticflickr.com/3637/3658139504_c33433f163_z.jpg?zz=1" alt="" />
                </div>
            </div>
        </div>
    </a>
</div>
</div>

CSS:

.hexaHolder{
    height: 115px;
    width: 99px;
    float: left;
}
.hexa img{
    width:100%;
    margin-top: -5px;
}
.hexa, .hexa div {
    margin: 0 auto;
    transform-origin: 50% 50%;
    overflow: hidden;
}
.hexa {
    text-align: center;
    margin: 0;
    width: 135px;
    height: 115px;
}
.hexa div {
  width: 100%;
  height: 100%;
}
.hexa {
  transform: rotate(120deg);
}
.hex1 {
  transform: rotate(-60deg);
}
.hex2 {
  transform: rotate(-60deg);
}

.hex-row {
    clear: left;
}

.hexaHolder.even {
    margin-top: 57.5px;
}

#wrap {
    min-width:600px;    
}

好吧，基本上我所做的就是使用 CodePen 中的代码作为起始块，因为它已经将图像放入六边形内。但是，我稍微修改了 CSS a HTML 以便您可以浮动六边形并定位它们，使它们看起来像您的示例。所有的功劳都需要归功于@geoffrey_crofte，因为他是六边形背后的天才。我刚刚定位并调整了大小。

干杯！

是的，是的，你可以做到这一点。创建它们需要一些数学知识，但组合起来看起来非常酷！
