react-bootstrap导航栏删除/修改媒体查询

Question

使用react-bootstrap v0.32.1。我的导航栏代码：

<Navbar inverse fluid>
    <Nav>
        <NavItem>
            left
        </NavItem>
    </Nav>
    <Navbar.Header>
        <Navbar.Brand>
            some title
        </Navbar.Brand>
    </Navbar.Header>
    <Nav pullRight>
        <NavItem>
            right
        </NavItem>
    </Nav>
</Navbar>

Looks good on the large screen (>768px):

But on the smaller screens it appear stacked:

如何禁止这种情况发生？
