Question

我正在尝试删除菜单和导航栏边距之间的填充。我似乎无法找到答案。

header nav #logo {
  padding: -10px; }

<header>
    <nav class="navbar navbar-expand-lg navbar-light bg-light" style="background-color: red;">
        <a class="navbar-brand" href="#">
            <img id="logo" src="images/logo.png" width="60" height="60">
        </a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent"
                aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarSupportedContent">
            <ul class="navbar-nav mr-auto">
                <li class="nav-item active">
                    <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Link</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link disabled" href="#">Disabled</a>
                </li>
            </ul>
            <form class="form-inline my-2 my-lg-0">
                <input class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search">
                <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
            </form>
        </div>
    </nav>
</header>

Answer 1

使用Bootstrap 4 spacing utilites for padding。

Decrease Padding Navbar Example

py-0将垂直（y轴）填充设置为0。

<nav class="navbar navbar-dark py-0 bg-primary navbar-expand-lg">
    <a class="navbar-brand" href="#">Logo</a>
    <div class="navbar-collapse collapse" id="navbarNav">
        <ul class="navbar-nav">
            <li class="nav-item py-0"><a href="#" class="nav-link">Link</a></li>
        </ul>
    </div>
</nav>

在我的情况下，不是导航垫是护垫，而是身体。我把py-0放在他的课上，准备就绪
