如何自定义Angular Material的输入/ md-input-container组件？

Question

如标题所述， 我该如何自定义这些元素？ 看来他们使用的透明背景很难在大多数背景调色板上观看

Answer 1

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。

对于您遇到的问题，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;
}

您可以根据需要更改color或background-color。

Answer 2

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)";

});

要更改占位符颜色，请执行此操作，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;
}

要自定义Angular Material的input / md-input-container组件，可以将此样式添加到个人样式表中。

md-input-container {
  display: inline-block;
  position: relative;
  padding-top: 2px;
  padding-bottom: 2px;
  padding-left: 2px;
  padding-right: 2px;
  margin: 1px 0;
  vertical-align: middle;
  /*
   * The .md-input class is added to the input/textarea
   */ }

   md-input-container .md-input {
     -webkit-order: 2;
         -ms-flex-order: 2;
             order: 2;
     display: block;
     margin-top: 0;
     background: none;
     padding-top: 2px;
     padding-bottom: 2px;
     padding-left: 2px;
     padding-right: 2px;
     border-width: 1px 1px 1px 1px ;
     line-height: 26px;
     height: 30px;
     -ms-flex-preferred-size: 26px;
     border-radius: 5px;
     border-style: solid;
     width: 100%;
     box-sizing: border-box;
     float: left; }

 md-input-container.md-input-focused .md-input,
 md-input-container .md-input.ng-invalid.ng-dirty {
   padding-bottom: 0;
   border-width: 0 0 2px 0; }

 md-input-container:not(.md-input-invalid).md-input-focused .md-input {
     border-color: black;
          }


md-input-container:not(.md-input-invalid).md-input-focused label {
    padding-top: 0px;
    color: green;
          }


md-input-container .md-errors-spacer {
       float: right;
       min-height: 0px;
       min-width: 0px; }
       html[dir=rtl] md-input-container .md-errors-spacer {
         float: left;
         unicode-bidi: embed; }
       body[dir=rtl] md-input-container .md-errors-spacer {

         unicode-bidi: embed; }
       md-input-container .md-errors-spacer bdo[dir=rtl] {
         direction: rtl;
         unicode-bidi: bidi-override; }
       md-input-container .md-errors-spacer bdo[dir=ltr] {
         direction: ltr;
         unicode-bidi: bidi-override; }

 md-icon {
   margin: auto;
   background-repeat: no-repeat no-repeat;
   display: inline-block;
   vertical-align: middle;
   fill: currentColor;
   height: 24px;
   width: 24px;}
   md-icon svg {
     pointer-events: none;
     display: block; }
   md-icon[md-font-icon] {
     line-height: 1;
     width: auto; }

 md-input-container > md-icon {
   position: absolute;
   top: 5px;
   left: 20px;
   right: auto; }
