【问题描述】：
我设计了一个 html5 页面，当他们的设备上没有互联网连接时，我想向访问我网站的人显示该页面。例如 www.sweetwater.com
我已经准备好了我的网页，我只想知道如何处理它以及将它放在哪里，以便在用户没有互联网连接时调用它

//And here is my css3 code:
/*---------------- Offline Notifier Page --------------*/
.navRibbon {
width: 100%;
height: 45px;
background-color: #2F2C2C;
border: 1px solid white;
margin: 0 0 2px;
}
.offlineWrapper {
width: 80%;
margin: auto;
text-align: center;
}
header {
background: url(../img/bubble-clean-clear.jpg) no-repeat;
background-size: 100% 100%;
width: 100%;
height: 200px;
margin: 0 auto 40px;
padding: 10px 0 0;
box-shadow: -3px 2px 20px 0 black;
}
.offlineBanner {
}
header>h1 {
font-size: 50px;
color: greenyellow;
text-shadow: -3px 3px 7px black;
margin: 10px auto;
}
header>.offlineBanner {
width: 70%;
margin: auto;
padding: 10px;
background-color: #5F3E8F;
opacity: .7;
}
header>.offlineBanner>h3 {
color: #fff;
line-height: 24px;
}
header>.offlineBanner>h4 {
color: yellow;
line-height: 18px;
}
.offlineWrapper>h2 {
font-size: 42px;
}
.offlineWrapper>.offlineLogo {
width: 45%;
margin: 0 auto 50px;
}
.offlineWrapper>.offlineLogo img {
width: 100%;
}
.offlineWrapper>.offlineCaution {
background-color: #9E2022;
color: aliceblue;
padding: 8px;
width: 40%;
margin: 20px auto 40px;
line-height: 33px;
font-size: 18px;
}
我没有采取这一步，因为我现在还不知道如何做，但是一旦我知道了，我希望在设备没有互联网时显示页面，如果有互联网连接，则显示正常的网站登陆页面.

你不能。

它不是特定于 CSS 的，但您可以使用
service workers并检测用户是否离线。此时，您可以加载离线体验。
