AngularMaterialTooltip过长偏移解决方法

### Angular Material Tooltip 内容过长偏移解决方法 本文针对Angular Material Tooltip组件在内容过长时，底部定位失效并出现向右偏移的问题，提供了一套有效的解决方案。首先介绍了利用`matTooltipPosition`属性进行基础定位的方法，随后重点讲解如何通过`matTooltipPanelClass`结合自定义CSS样式，控制Tooltip面板的宽度，从而避免因长文本内容超出默认宽度而导致的显示错位，确保Tooltip在各种情况下都能正确、美观地显示，提升用户体验。

Angular Material Tooltip位置控制与长内容适配

Angular Material的Tooltip组件（matTooltip）为用户提供了便捷的提示信息展示能力。然而，当Tooltip内嵌的文本内容过长时，即使设置了如“底部”等定位，Tooltip面板仍可能出现意外的水平偏移，尤其表现为向右延伸过远，影响用户界面布局。这通常是由于Tooltip面板的默认宽度不足以容纳长文本，导致其在尝试显示全部内容时突破了预期的水平限制。

本教程将详细介绍如何通过Angular Material提供的属性来精确控制Tooltip的位置，并着重解决长文本内容导致的显示异常问题。

1. 理解 matTooltipPosition 属性

matTooltipPosition是控制Tooltip相对于触发元素显示位置的核心属性。它定义了Tooltip面板的初始对齐方式。可用的值包括：

• above：在触发元素上方显示。
• below：在触发元素下方显示。
• left / before：在触发元素左侧显示。
• right / after：在触发元素右侧显示。
• bottom：在触发元素下方居中显示（这是常见的一种底部定位）。

对于原始问题中提到的“底部定位但仍向右偏移”的情况，这意味着matTooltipPosition="bottom"或"below"可能已经设置。虽然这些属性确保了垂直方向的定位，但它们不直接限制Tooltip面板的水平宽度。

示例代码：基本定位

<!-- app.component.html -->
<button mat-raised-button
        matTooltip="这是一个相对较短的提示文本。"
        matTooltipPosition="below">
  短文本提示
</button>

<button mat-raised-button
        matTooltip="这是一个非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常非常
