It is a set of UI components created by Google.

It is a conventional CSS with a small footprint.
It is open source and needs the jQuery JavaScript library to work correctly. It may be used to build reusable web components and is cross-browser compatible. Cards, tabs, navigation bars, toasts, and more upgraded and customized features are included. It offers updated variations of typical user interface elements like buttons, checkboxes, and text fields that have been modified to adhere to Material Design principles.
什么是对话框？
对话框是一种图形控件元素，以小窗口的形式出现，并向用户传达信息，同时要求用户做出反应。
Depending on whether they prevent communication with the software that opened the dialog, dialog boxes are categorized as "modal" or "modeless." The desired user interaction determines the type of dialogue box that will be displayed.
HTML元素"dialog"表示对话框或其他交互元素，如子窗口、检查器或可关闭的警告。
Dialogs in Materialize CSS
Dialogs in Materialize CSS give users access to more information as needed. These are not immediately displayed on the website. The information needed at that particular time is related to the dialog transitions. In order to display dialogs, Materialize offers several options. Dialogs are pieces of material that are normally hidden on a page but pop up with more information when required. The user shouldn't feel startled by the changes, which should make sense from the dialog's appearance. Toasts in Materialize give you a simple way to give your users discreet alerts. You may test out how responsively these toasts are put and sized by clicking the button below on various device sizes.
Use JavaScript code to programmatically invoke the Materialize.toast() function to accomplish this. An HTML String may also be supplied as the first argument. Once the toast has been dismissed, you can have it call back a certain function. You can easily customize the CSS style classes and add it to the toasts as as optional parameter.
语法

Parameter

timeDuration- 用于指定在屏幕上显示消息的时间持续时间。
Class- 用于指定要应用于提示框的样式类的类型。
