[Vuejs]-How to style v-calender in vue js?

‘themeStyles’ never seem to work. You can style the calendar by overriding its css. It is not in any iframe.

.vc-container {
    width: 100%;
    border-color: transparent;
    background-color: transparent;
}
.vc-pane-container {
    background-color: '#ebebeb';
}
.vc-title {
    font-size: 16px;
    color: white;
    font-family: "GTWalsheimPro Medium", serif;
}
