h5页面怎么固定横屏且100%展示?

发布于 2022-09-06 02:49:59 字数 701 浏览 19 评论 0

1.需求是在h5页面上，固定横屏展示（不论用户怎么拿手机，始终横屏展示，强迫诱导用户横屏浏览）
2.demo源码
3.目前的问题：

  • 手机横屏时，没有什么问题，可以正常展示
  • 手机竖屏时，能够横屏，但是上下有留白，内容不是100%铺满

4.按照 @supreme 的回答，基本可以实现，但是出现了新的问题：

  • 第一，在安卓手机里竖屏情况下，强制横屏，内容并没有展示完全，尤其是在微信里面，需要用户设置-通用-开启横屏，真正横屏才能看到全部内容
  • 第二，在苹果手机里，开启手机的横屏模式下，可以正常显示，但是关闭之后，显示的内容还是不能100%全屏，依旧有留白

内容100%的问题已解决，把.main的overflow属性去掉，在微信里面试好的，但是浏览器中存在问题，再套一层dom就好了，具体代码如下

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />

  <!-- <link rel="stylesheet" href="test2.less"> -->
  <style>
    html {
      font-size: 100px;
      margin: 0;
      padding: 0;
      font-family: '微软雅黑',Arial,Helvetica,'microsoft yahei',sans-serif;
      background: #f2f2f2
    }
    * {
        margin: 0;
        padding: 0
    }
    body {
        margin: 0 auto;
        font-size: 12px;
        color: #333
    }
    .main {
        /*background-color: #999;*/
    }
    .main_second{
         background-color: #999;
         height: 100%;
         overflow: auto;
    }
    p {
        line-height: 30px;
        font-size: 16px
    }
    .title {
        font-size: 24px;
        line-height: 40px;
        text-align: center;
        background-color: #fff
    }
    @media screen and (orientation: portrait) {
        .main {
            -webkit-transform:rotate(-90deg);
            -moz-transform: rotate(-90deg);
            -ms-transform: rotate(-90deg);
            transform: rotate(-90deg);
            width: 100vh;
            height: 100vh;
            /*去掉overflow 微信显示正常，但是浏览器有问题，竖屏时强制横屏缩小*/
            overflow: hidden;
        }
        
    }
    @media screen and (orientation: landscape) {
        .main {
