Can't change fonts in TextField in NativeScript

Question

I just started with NativeScript/Angular and I am not the best with html and css and would like to style the hint font in the TextFields. like changing the color, font-size, ... I am not sure why it does not work in the "input-field" class. I would be very thankful, if you someone could answer soon, thank you:)

.form {
    background-color: #6F9DE1;
    margin-top: 2.3%;
    margin-bottom: 10%;
}

.header {
    font-size: 25;
    text-align: center;
    color: #111;
    margin-top: 5%;
    height: 60;
}

.fields {
    margin-bottom: 20%;
    margin-left: 30;
    margin-right: 30;
}

.input-field {
    height: 45;
    margin-bottom: 20;
    background-color: #4587AD;
    border-radius: 100px;
    /* color: #fff;                would like to change the color here */
}

.input {
    font-size: 20;
    color: #fff;
    border-bottom-width: 0;
    border-bottom-color: transparent;
}

.btn-primary {
    height: 40;
    background-color: #6F9DE1;
    font-size: 20;
    font-weight: 200;
    color: #fff;
    border-radius: 100px;
}

.btn-secondary {
    height: 40;
    color: #4587AD;
    border-radius: 100px;
}

I found a working solution. You can use style.placeholderColor for changing the color, for example: style.placeholderColor="white" in the TextField tag

<StackLayout class="input-field">
                <TextField style.placeholderColor="white" class="input" hint="Email" 
                 keyboardType="email"></TextField>
</StackLayout>
