在@ Ajax.ActionLink中，html样式不起作用MVC，AJAX.ActionLink

Question

我有newxt Ajax.ActionLink

@Ajax.ActionLink(
        "Добавить",
        "CreatPlayer",
        null,
        new AjaxOptions()
        {
            HttpMethod = "GET",
            UpdateTargetId = "view-creating-form",
            InsertionMode = InsertionMode.Replace
        },
        new
        {
            @class = "toggle-tab"
        }
    )

还有他的css样式

css styles.toggle-tab {
    font-family: 'Philosopher', sans-serif;
    font-size: 1.4em;
    color: black;
}

问题是样式不起作用，导致了通常的链接样式。如何解决它以及什么问题？Don't see css
