How do I customize Angular Material's input/md-input-container component?
提问by dragonmnl
As stated in the title, how do I customize these elements? It seems they are using transparent background which is very difficult to view on most background palettes
如标题所述，如何自定义这些元素？似乎他们正在使用透明背景，这在大多数背景调色板上很难查看

Add one blank css file after "angular-material.css" and inside that blank css file overwrite the rules you want to customize.
在“angular-material.css”之后添加一个空白 css 文件，并在该空白 css 文件中覆盖您要自定义的规则。
For the problem you are facing I added the following rules in my custom.css.
对于您面临的问题，我在 custom.css 中添加了以下规则。
md-input-container.md-default-theme label,
md-input-container.md-default-theme .md-placeholder{
color:grey !important;
}
Here you could change coloror background-coloras you like.
在这里，您可以更改color或background-color随心所欲。

I would recommend to use the palette configuration:
我建议使用调色板配置：
app.config(function($mdThemingProvider) {
//change default color for primary
var indigo = $mdThemingProvider.extendPalette('indigo', {
'500': '569fd4'
});
$mdThemingProvider.definePalette('indigo', indigo);
//change default color for warn
var indigo = $mdThemingProvider.extendPalette('red', {
'500': 'ff5800'
});
$mdThemingProvider.definePalette('red', indigo);
$mdThemingProvider.theme('default').primaryPalette('indigo').warnPalette('red');
//here you change placeholder/foreground color.
$mdThemingProvider.theme('default').foregroundPalette[3] = "rgba(0,0,0,0.67)";
});

To change placeholder color do this, it changes the placeholder color to White:
要更改占位符颜色执行此操作，它将占位符颜色更改为白色：
/* do not group these rules */
.your-pre-defined-container > md-input-container > input::-webkit-input-placeholder {
color: #FFF;
}
.your-pre-defined-class > md-input-container > input:-moz-placeholder {
/* FF 4-18 */
color: #FFF;
}
.your-pre-defined-class > md-input-container > input::-moz-placeholder {
/* FF 19+ */
color: #FFF;
}
.your-pre-defined-class > md-input-container > input:-ms-input-placeholder {
/* IE 10+ */
color: #FFF;
}
