【问题描述】：
请帮我解决这个代码。它在 pc 中看起来很棒，但在移动视图中只覆盖了一半的屏幕。请指导我解决这个问题。下面是我的 HTML 和 CSS 代码。我将非常感谢您的帮助。我认为容器流体类存在一些问题，因为它没有覆盖整个屏幕
body{
/* background: no-repeat fixed url(../images/background.png); */
font-family: 'open Sans';
color: white;
}
/* Navbar section */
.container-fluid{
background: no-repeat fixed url(../images/background3.png);
background-size: cover;
padding: 8% 15%;
height: 710px;
}
.navbar-light{
background-color: #78c9cb;
color: grey;
font-size: 200%;
}
/* Create Account Section */
.card{
max-width: 800px;
padding: 0;
text-align: center;
/* margin-top: 10%; */
}
.create{
font-size: 3rem;
padding:0;
font-weight: bolder;
}
.form-group{
padding: 0.8rem;
}
@media (max-width:800px) {
.container-fluid{
padding: 20% 15%;
}
body{
max-height: 100%;
}

在移动端查看媒体查询中添加
padding-0;到container-fluid -
试试这个
@media (max-width:375px) { .container-fluid{ padding: 0; } }// iphone @375 -
我试过了，但它也只是覆盖了一半宽度
