Question

我正在为网站制作一个登录表单。

我正在尝试将一些文本放在表单上的面板标题中，但它不是一直居中的。

// starts here
tabPane.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<Tab>() { 
    @Override 
    public void changed(ObservableValue<? extends Tab> observable, Tab oldTab, Tab newTab) {
        if(newTab.equals (total)) {            
            System.out.print(total.isSelected());
        }
    }
});

/*

  padding-top: 90px;
}

.panel-login {

.login-button {

.login-register {

}

正如你所看到的，如果你放大它，它只会在一点点卡在左侧。我希望它完全集中。

尝试像这样做

<div style="text-align:center">
    <a href="#login" class="active" id="login-form-link">Login</a>
</div>

文本在面板标题中不是一直居中的？
