调整角度材料的圆形进度

Question

我正在使用Angular Material为登录表单构建一个指令:

当用户点击登录时,会出现循环进度,表明他现在正在登录.进度确实显示和隐藏,我的问题是它的大小.我希望它在相似大小的登录文本旁边.我试图添加style="transform: scale(0.5)"或style="width: 20px",但都没有影响它的大小.

如何调整进度,以使其适合文本？

模板

<form name="loginForm" ng-submit="loginCtrl.login()">
    <md-input-container flex>
        <label for="usr">Username</label>
        <input type="text" ng-disabled="login.loading" name="usr" id="usr" maxlength="50" ng-model="login.user" required />
    </md-input-container>
    <md-input-container flex>
        <label for="pwd">Password</label>
        <input type="password" ng-disabled="login.loading" name="pwd" id="pwd" ng-model="login.password" required />
    </md-input-container>
    <md-button class="md-raised md-primary" ng-disabled="loginForm.$invalid || login.loading" type="submit">
        Login
        <md-progress-circular md-mode="indeterminate" ng-show="login.loading" class="md-accent">
    </md-progress-circular></md-button>
</form>

指示

angular
    .module('app')
    .controller('LoginCtrl', ['$scope', 'AuthService', '$log', function ($scope, AuthService, $log) {
        $scope.login = {
            loading: false,
            password: '',
            user: ''
        };

        this.login = function () {
            $scope.login.loading = true;

            // Do the login, this might take longer
            AuthService.login($scope.login.user, $scope.login.password, function (data) {
                $scope.login.loading = false;

                if(data.success) {                  
                    $log.debug('login successful');
                }
                else {
                    $log.debug('login failed');
                }
            });
        };
    }])
    .directive('loginForm', function () {
        return {
            restrict: 'EA',
            scope: {},
            controller: 'LoginCtrl',
            controllerAs: 'loginCtrl',
            templateUrl: '/templates/directives/loginForm.html'
        };
    });

设置较小的值md-diameter是不够的.按钮改变其宽度和高度.所以这是我在Codepen上的例子,在按钮中显示漂亮的微调器.

希望它能帮到你!
