我正在尝试在输入文本字段之外的 from 中设置按钮的样式。除非我降低按钮的字体大小（这是我需要做的）并给我的按钮一个背景渐变，否则 Everyting 有效。如果我降低字体大小（或设置除 1em 之外的任何内容），我的按钮文本下方会有一个神秘的空间，我不知道它来自哪里。如果我提高填充以匹配降低的字体大小，空间仍然存在。如果我向按钮添加渐变，则周围表单的框阴影消失。

我该如何解决这两个问题？

这是一个工作示例：http: //jsfiddle.net/WTrQy/

HTML：

<section class="grid-100 search">
    <header class="none">
            <h1>Schnell finden</h1>

    </header>
    <form class="grid-90 grid-parent" action="action.php">
        <input type="text" aria-required="true" placeholder="Suche nach PLZ oder Ort" class="grid-80 mobile-grid-80">
        <button class="grid-20 mobile-grid-20">Suchen</button>
    </form>
</section>

CSS：

section.search h1 {
    margin-top: 1.7em;
    margin-bottom: .5em;
    font-size: 1.285714285714286em;

您的按钮现在没有文本框那么高，因为您在 ems 中添加了填充，因此使用较小的字体大小，您在按钮上的填充将少于文本框。

在其他填充线下方添加以下行，这将解决问题：

section.search form button {
    padding: 1.2em 0.7em 1.1em 0.7em;
}

你的盒子阴影没有显示，因为 0.2em 对阴影来说太小了，如果你把它增加到至少 0.5em，你应该能够看到你的阴影

这是一个工作示例
