问题描述

我正在学习Polymer.我正在构建用于学习Polymer的应用程序使用 paper-item 元素.我选择paper-item为它的外观.但是,当我单击纸张项目时,背景变为深灰色.如何删除此行为?我希望paper-item的背景始终为白色.但是,无法弄清单击或选择paper-item时如何设置背景色.

I am learning Polymer. The app I'm building to learn Polymer uses the paper-item element. I've chosen the paper-item for its look. However, when I click the paper-item, the background changes to a dark gray. How do I remove this behavior? I want the background of the paper-item to always be white. Yet, cannot figure out how to set the background color when the paper-item is clicked or selected.

感谢您的帮助,祝您假期愉快!

Thank you for your help and have a great holiday season!

推荐答案

我认为这是需要通过重新定义mixin来更改的重点行为:

I think it's the focused behavior that needs to be changed by redefining the mixin:

<template>
  <style>
    :root /* or paper-item */ {
      --paper-item-focused: {
        background-color: white;
      }
    }
  </style>
  <paper-item></paper-item>
</template>

如果这不起作用,请尝试使用--paper-item-selected而不是--paper-item-focused.

If this doesn't work try --paper-item-selected instead of --paper-item-focused.
