在使用以下组件的体系结构的应用程序上应用媒体查询(响应行为)时遇到一些问题
基本组件::它使用默认封装,在某些情况下,在某些情况下,我们在应用PrimeNG外部模块时会使用外部插件。想法是将这些基本组件移至其他应用程序。这些都集成在其自己的共享模块中。
品牌组件::它重用基本组件,应用自定义样式和翻译文本,做一些特定的事情,并且使用本机封装(以与基本组件区分开),但是它没有应用业务逻辑。这些都集成在其自己的品牌模块中,该模块导入共享模块。
业务组件::它重用品牌组件并在此处应用自己的业务逻辑(在多个视图中使用时)。这些都集成在其自己的导入品牌模块的业务模块中。这些组件实现默认的角度封装模式。
然后我们拥有视图,这些视图集成在其自己的模块中并导入业务模块。它将使用品牌和/或业务组件,在这里我们面临一些与CSS媒体查询有关的问题。这些视图使用默认的角度封装模式。
具体情况是,我们试图针对特定视图自定义输入字段,以便针对响应情况正确运行(移动设备,平板电脑和台式机的方向不同)。为此,我们使用外部插件的角度弹性布局(测试版7)
此输入字段位于基础组件上,但我们将其作为商标用例。我们想要的是更改其在商标上设置的默认宽度/高度,以适应将其封装的div容器。
这是我们到目前为止所做的:
特定视图的scss:

存在以前的自定义类,并在品牌输入字段组件中使用了这些自定义类,以便根据不同的情况更改其UX。

那么这里可能出什么问题了? 我们是否在特定视图上错误地使用了:host:ng-deep??我们已经看到,如果我们直接在品牌输入字段sass文件上应用这些媒体查询,效果很好(删除:host:ng-deep标签)
答案 0 :(得分:1)
但是,我必须在媒体查询上设置的所有属性值中添加!important才能生效。
为解决此问题,我在Vikas上提到了in this link。
您可以将其放在单独的文件中,并将其包含在将要使用的任何文件中。
$phone : '(max-width: 480px)';
$phone-landscape : '(max-height: 480px)';
$tablet-portrait: '(max-width: 767px)';
$tablet-landscape: '(min-width: 768px) and (max-width: 979px) and (max-height: 768px)';
$large-desktop: '(min-width: 1200px)';
$non-retina: 'screen and (-webkit-max-device-pixel-ratio: 1)';
$retina: '(min--moz-device-pixel-ratio: 1.5),
(-o-min-device-pixel-ratio: 3/2),
(-webkit-min-device-pixel-ratio: 1.5),
(min-device-pixel-ratio: 1.5),
(min-resolution: 144dpi),
(min-resolution: 1.5dppx)';
@mixin respond-to($media) {
@media only screen and #{$media} {
@content;
}
}
,然后在声明中使用调用:
.bookItem {
max-height: 450px;
min-height: 150px;
padding: 25px;
@include respond-to($phone) {
max-height: 150px;
padding: 15px;
}
}
它有效。
答案 1 :(得分:0)
尝试使用empty()
代替:host /deep/
,如下所示
:host ::ng-deep
或
使用:host /deep/ {
/*your style goes here*/
}
代替encapsulation: ViewEncapsulation.None
