I just want edit css off default login page. I tested on private instance, all is ok.

However, When I test on UAT, The text color of the placeholder attribute cannot be changed, it remains the default color. This is code:

HTML:

            <input id="password" placeholder="Password" name="password" ng-keypress="c.message = ''"
ng-click="c.message = ''" class="login_input"
type="password" ng-model="c.password" />

CSS:

       .login_input::-webkit-input-placeholder {
            color: white !important;
       }
