Css 使用带有angular11的AutoRefixer

我正在将angular11与

SCSS

一起使用。例如，我有以下课程：

.freeSpace {
    flex: 1;
    display: flex;
    align-items: flex-end;
    width: 100%;
    max-width: 600px;
}

但是，当我执行

ng build--prod时，它不会转向：

.freeSpace {
    -webkit-box-flex: 1;
        -ms-flex: 1;
            flex: 1;
    display: -webkit-box;
    display: -ms-flexbox;
    display: flex;
    -webkit-box-align: end;
        -ms-flex-align: end;
            align-items: flex-end;
    width: 100%;
    max-width: 600px;
}

如何强制angular使用AutoRefixer

          }
        }
      }
    }
  },
  "defaultProject": "we19-app"
}

我希望我的最终
scss
文件看起来像前缀器。
当我在浏览器中打开我的应用程序时，会显示“常规”（未转换为autoprefixer代码）scss代码

另外，当我手动将以下内容附加到我的SCS时：

.freeSpace {
    -webkit-box-flex: 1;
        -ms-flex: 1;
            flex: 1;
    display: -webkit-box;
    display: -ms-flexbox;
    display: flex;
    -webkit-box-align: end;
        -ms-flex-align: end;
            align-items: flex-end;
    width: 100%;
    max-width: 600px;
}

当我执行
ng build--prod
并在浏览器中查看应用程序时，所有这些“额外”SCS（例如
display:-ms flexbox
）都会被忽略

My.browserslistrc：

# This file is used by the build system to adjust CSS and JS output to support the specified browsers below.

not IE 11 # Angular supports IE 11 only as an opt-in. To opt-in, remove the 'not' prefix on this line.

如果选中，您将看到它仅支持最新浏览器

因此，如果你构建你的应用程序，它只会添加必要的前缀。如果选中，您将看到所有当前浏览器都支持
display:flex
<代码>显示：-ms框

仅受IE10支持，而angular不支持。因此，用不必要的前缀填充CSS是没有意义的。这就是它被过滤掉的原因。

您可以如下修改

.browsslistrc

文件

Safari 6
IE 10

这将导致以下css

.freeSpace {
    -webkit-box-flex: 1;
    -ms-flex: 1;
    flex: 1;
    display: -webkit-box;
    display: -ms-flexbox;
    display: flex;
    -webkit-box-align: end;
    -ms-flex-align: end;
    align-items: flex-end;
    width: 100%;
    max-width: 600px;
}

为什么要构建angular应用程序并为无法运行angular应用程序的浏览器创建CSS（

-ms flex

仅由IE10使用，

-webkit box

由chrome版本~20使用）这些浏览器无法运行angular应用程序，他们不了解其Javascript。所以没有理由把它放在你的CSS中。我想支持移动原生应用。简单地说，当我在Safari中打开应用程序时，它缺少

display:-webkit框

，因此我没有flex，但为什么angular不支持

Safari

browser？Safari理解

display:flex

根据我发布的链接，它很好。您需要safari的哪个版本的前缀？那么我是否应该用

safari 6

替换

上两个safari主要版本

？是的，只需将

而不是IE 11

替换为

IE 10

，将

上两个safari主要版本

替换为

safari 6
