我已经使用 Angular 实现了一个模态窗口组件，但在将组件渲染到屏幕中心时遇到了问题。它呈现在不同屏幕上的不同位置。我尝试了很多谷歌搜索解决方案，但到目前为止似乎都没有奏效。
如果您在我的组件加载时按照逻辑看到下面的内容，它将应用样式 modal-dialog modal-lg modal-dialog-centered 如果指定的大小为 3 成分。当我检查元素时，我可以看到正在应用的样式
import { Component, Input, OnChanges, OnInit, SimpleChange, SimpleChanges, DoCheck } from '@angular/core';
declare var $: any;
@Component({
selector: 'shared-modal',
templateUrl: './shared-modal.html'
})
export class SharedModal {
_isopen = false;
private _modalSize = 1; // 1:normal, 2: medium, 3: large
public get modalSize() {
return this._modalSize;
}
@Input()
public set modalSize(value) {
this._modalSize = value;
}
get open(): boolean {
return this._isopen;
}
@Input()
set open(val: boolean) {
this._isopen = val;
}
getModalDialogClass() {
if (this.modalSize == null || this.modalSize <= 1 || this.modalSize > 3) {
return 'modal-dialog';
} else if (this.modalSize <= 2) {
return 'modal-dialog modal-md';
} else if (this.modalSize <= 3) {
return 'modal-dialog modal-lg modal-dialog-centered ';
}
}
}
模态.scss
.modal-dialog {
max-width: 70%;
margin:5% auto;
}
.modal-content {
border-radius: 0;
}

我相信这个问题可以用 flexbox 来解决。查看一些文档，看看是否有任何帮助你(一定要将容器设置为 display: flex 正如我上面的答案所说) https://css-tricks.com/snippets/css/a-guide-to-flexbox/
关于html - 模态不渲染到屏幕中央，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54833114/
