CSS Sprites - 如何对齐所有 Sprite 按钮答案

【问题标题】：CSS Sprites - How to Align-bottom all Sprite ButtonsCSS Sprites - 如何对齐所有 Sprite 按钮
【发布时间】：2011-08-01 13:10:51
【问题描述】：

我的网络应用底部导航有 9 个按钮（想想 iOS 导航栏 - 但这不是移动应用）。

所有按钮都是具有 3 种状态的 Sprite 图片。

如何将所有图像（即按钮）对齐到导航栏（或 div）的底部？基本上，每个图标的大小略有不同，在 PNG 中，每个图标下方都有文本。

我希望所有文本都对齐，因此所有按钮都必须底部对齐。

我该怎么做？ CSS解决方案？ HTML 解决方案？

感谢您的帮助，

【问题讨论】：

为什么不在这里显示 HTML？您也许可以使用绝对定位或使用 left: x 和 top:y 。
谢谢，刚刚添加了标记，HTML在底部:)

标签： html css css-sprites sprite

【解决方案1】：

这似乎更像是一个 Photoshop 的问题，而不是任何事情。假设您的标记结构如下：

<nav>
     <ul>
          <li class="icon-a">
               <a>
                    <span class="icon"></span>
                    Text
               </a>
          </li>

          <li class="icon-b">
               <a>
                    <span class="icon"></span>
                    Text
               </a>
          </li>
     </ul>
</nav>

找到最高图标的高度并将其设置为<li> 的高度。然后找到最宽图标的宽度并将其设置为<li> 的宽度。

你必须非常小心地在你的 sprite 文件中布局图标，并根据我上面提到的最大宽度和高度均匀地排列图标（我会使用 Photoshop 标尺和参考线来创建一个网格，让你的生活更轻松） .每个图标状态应该是连续的。对齐底部图标的关键是如何在 Photoshop 中布置图标。

假设你的最高图标是 40 像素，最宽的图标是 30 像素，我会这样做。我将高度设置为 60 像素，因此底部有空间让文本位于图标下方。

nav li {
   width: 30px;
   height: 60px;
   display: block;
   float: left;
}

nav li a {
   width: 30px;
   height: 60px;
   line-height: 15px;
   display: block;
   text-align: center
}

nav li a span {
   width: 30px;
   height: 40px;
   padding-bottom: 5px;
   display: block;
   background: url(icons.png) no-repeat
}

nav li.icon-a span {background-position: 0 0}
nav li.icon-a span:hover {background-position: 0 -40px}
nav li.icon-a span:active {background-position: 0 -80px}

nav li.icon-b span {background-position: -30px 0}
nav li.icon-b span:hover {background-position: -30px -40px}
nav li.icon-b span:active {background-position: -30px -80px}

【解决方案2】：

无论每个图标的大小如何，您都应该让您的精灵在其上放置均匀的图标。

如果您的每个按钮都有一个 36 x 36 像素的空间，那么您需要将已对齐的每个图标放置在精灵中 36x36 正方形的底部，然后您只需使用 36 像素网格定位精灵。

【讨论】：

我确实按照您推荐的方式制作了所有个人 PNG。由于有很多 PNG，我通过 CSS Sprite Generator (spritegen.website-performance.org) 将它们全部放在一个巨大的 PNG 上，它为我提供了每张图像的所有坐标。
我现在看到您拥有从 43px 到 112px 高度的各种尺寸的按钮（除了图标）。我认为这需要大量的手动操作，包括编辑精灵。
