<nav id="section_navbar" class="navbar navbar-expand-lg fixed-top">
        <div class="mx-auto my-2 order-0 order-md-1 position-relative">
            <div id="top_logo" class="container-fluid">
                <span>VirtualQR</span>
            </div>
        </div>
        <div class="navbar-collapse collapse w-100 dual-collapse2 order-2 order-md-1">
            <ul class="navbar-nav ml-auto">
                <li class="nav-item">
                    <a class="nav-link" href="#section_navbar">Home</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#section_howdoesitwork">How does it work?</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#section_pricing">Pricings</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#section_contact">Contacts</a>
                </li>
            </ul>

我无法通过导航链接更改颜色。我尝试了其他帖子解决方案，但无论如何都无法使它正常工作。我不知道这是否与我的代码有关。

Answer 1

欢迎使用堆栈溢出。这就是您可以做的。

baseURL = "https://api.instagram.com/oauth/access_token"

append = "client_id=\(API.INSTAGRAM_CLIENT_ID)&client_secret=\(API.INSTAGRAM_CLIENTSERCRET)&grant_type=authorization_code&redirect_uri=\(API.INSTAGRAM_REDIRECT_URI)&code=\(code)"

request.httpMethod = "Post"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField:"Content-Type");

/* Select bootstrap link */

.link{
  color: gray;
}

Answer 2

使用以下CSS选择器，您将能够更改nav-link类的颜色。

.nav-link {
