css - 使用 Bootstrap 主题时出现异常背景问题 - ASP.NET Core

我有一个使用 bootstrap 主题的 html 页面。我对 CSS 样式有一个小问题。这是我从未遇到过的问题。问题是背景不会在页面加载时填满页面，只有在调整页面大小时它才会填满页面。有什么建议么？

谢谢，

这里是_Layout.cshtml代码；

</html>

这里是 Index.cshtml 代码(这不是导致问题的原因)；

@{
    ViewData["Title"] = "About";
}

<style>
    *{
        text-align:center;

    }

</style>
<body >
    <img src="~/img/asset 1.jpg"/>

    <h1>Welcome to Hylands Biggest Loser!</h1>
    <h2>Click the buttons on the side. They will allow you to view your weights, progress, and your overall weekly summary.</h2>
    <h2>You can also view the other members in your group, as well as a weekly summary for all members.</h2>
</body>

最佳答案

将所有主要包装元素的高度设置为 100%，并且背景应始终至少占据页面的 100%。

添加这个CSS样式:

html, body, #wrapper, #page-wrapper { height: 100%; }
