我有两个按钮，并且不希望它们之间有一个空格。但是以下方法不起作用：

<gwt:FlowPanel styleName="{style.pad}">
    <gwt:Button text="foo" />
    <gwt:Button text="bar" />
</gwt:FlowPanel>

<ui:style>
    .pad .gwt-Button {
            margin-right: 20px !important;
    }
</ui:style>

结果：按钮并排对齐，它们之间没有空格。为什么？？

最佳答案

知道了：我必须在ui：style声明中使用@external gwt-Button;。
