Customize bootstrap navbar

Hi !

I’m trying to customize the links text of the bootstrap navbar in react.
I had a menu with dropdown with of react-router and I want to customize the font of the main menu items.

It’s only works when I add an Id to the links.
I tried several solutions: add custom classes, element selector in my scss but it doesn’t work.

Is there a better solution than the id ?

Thanks !

 <nav role="navigation" className="navbar navbar-fixed-top">
	<div className="container-fluid">
         	<div className="collapse navbar-collapse col-md-offset-4">
                       	<ul className="nav navbar-nav">
                            <li className="dropdown">
                                <Link href="#" className="dropdown-toggle navbar__category" data-toggle="dropdown" role="button" >Customize Item</Link>
                                <ul className="dropdown-menu">
                                    <li><Link to="/">Sub Item title</Link></li>
                                    <li>Sub item</li>
                                    <li>Sub item</li>
                                    <li>Sub item</li>
                                    <li>Sub item</li>
                                </ul>
                            </li>
                            <li className="dropdown">
                                <Link href="#" className="dropdown-toggle navbar__category" data-toggle="dropdown" role="button" >Item Customize</Link>
                                <ul className="dropdown-menu">
                                    <li><Link to="/">Sub Item title</Link></li>
                                    <li>Sub items</li>
                                    <li>Sub items</li>
                                    <li>Sub items</li>
                                    <li>Sub items</li>
                                </ul>
                            </li>
                 		</ul>
         	</div>
	</div>
</nav>

Solved !

I add manually bootstrap in my main.scss to overwrite the file.
