如何删除
<paper-button>
元素内元素周围的所有空白(仅)<paper-dialog>
?
因此,例如,悬停效果应该一直到边缘。但我仍然想保留段落文本周围的空白。
演示:
- 单击此 JS Bin以获取工作示例代码。
- Safari 用户特别注意:使用 Chrome 观看演示。
尝试:
在代码和演示中,我评论了我之前的所有尝试/* No effect */
。
代码:

<paper-dialog id="dialog">
<p>
I want to remove the white space around the below buttons
so the hover effect extends to the edges of this dialog.
But I want to keep the white space around this text.
</p>
<div class="layout vertical">
<paper-button>One</paper-button>
<paper-button>Two</paper-button>
<paper-button>Three</paper-button>
</div>
</paper-dialog>
<paper-button on-tap="openDialog">Open Dialog</paper-button>
</template>
<script>
Polymer({
is: 'x-element',
openDialog: function(){
this.$.dialog.open();
}
});
</script>
</dom-module>
</body>
