html - 我的 Sidenav 阻止页面中的内容

Question

我正在使用固定位置的侧边栏导航。问题是它会在每个打开的页面上阻止其背后的内容:

enter image description here

它不应该是这样的。当屏幕改变它的大小时，我希望侧边栏和页面内容并排，而不是一个在另一个之上。我怎样才能让它发生？侧边栏的HTML和CSS代码如下:

HTML:

    <div class="sidenav">
    @Html.ActionLink("Home", "Index", "Home", new { area = "" }, new { @class = "navbar-brand" })
    @Html.ActionLink("Vendedores", "Index", "Vendedores", new { area = "" }, new { @class = "navbar-brand" })
    @Html.ActionLink("Vendas", "Index", "Venda", new { area = "" }, new { @class = "navbar-brand" })

    <footer class="footer">
        <p>&copy; @DateTime.Now.Year - Vendedores</p>
    </footer>

</div>

<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>

<div class="container body-content">
    @RenderBody()
    <hr />
</div>

CSS:

    /*CSS da barra lateral*/
.sidenav {
    height: 100%;
    width: 250px;
    position: fixed;
    z-index: 1;
    float: left;
    top: 0;
    left: 0;
    background-color: #111;
    padding-top: 60px;
}

.sidenav a {
    padding: 8px 8px 8px 32px;
    text-decoration: none;
    font-size: 25px;
    color: #818181;
    display: block;
    transition: 0.3s;
}
/* 2017 - Vendedores*/
.footer {
    color: #818181;
    position: fixed;
    left: 2%;
    bottom: 0px;
    width: 100%;
}

为您的主要内容留出与固定侧边栏宽度相同的左边距.. IE..

margin-left: 100px;
