IOS（iphone）上的高度不正常

I've created this website on codepen. While trying to make it responsive for all platforms I ran into a problem. It appears a single div covers the whole page (only on IOS) and not all heights are working properly (meaning nothing fits).

我在codepen上创建了这个网站。在尝试使其响应所有平台时,我遇到了问题。看起来单个div覆盖整个页面(仅在IOS上)并且并非所有高度都正常工作(意味着什么都不适合)。

I've been at it for days and still have no clue, why all the heights and rules don't apply on IOS.

我已经好几天了,仍然没有任何线索,为什么所有的高度和规则都不适用于IOS。

I've tried removing the video-section which reveals most of the page except the eind section which is just a blank white.

我已经尝试删除视频部分,它显示了除了eind部分之外的大部分页面,只是一个空白的白色。

I've tried adding max-height which does reveal some of the other content, but it also seems as if the page can't get any taller on IOS so I'm still limited to a space to work with. Also it doesn't seem a proper solution.

我已经尝试添加max-height,这确实揭示了其他一些内容,但是看起来好像页面在IOS上不能更高,所以我仍然只能使用一个空间。它似乎也不是一个合适的解决方案。

I've tried changing the position but with no avail.

我试过改变位置,但没有用。

It just seems as if the heights don't properly work on IOS

看起来好像高度不适合IOS

Can anyone help me figure out why this is happening?

任何人都可以帮我弄清楚为什么会这样吗?

3 个解决方案

#1

It's not matter of IOS, it's matter of responsiveness. You have set fixed height to each section so it is overlapping with each others on mobile devices.

这不是IOS的问题,而是响应的问题。您已为每个部分设置了固定高度,因此它在移动设备上彼此重叠。

Just set all section height to height: 100vh.

只需将所有截面高度设置为高度:100vh。

And

@media (max-width: 430px){
    .introductie {
    height: 300vh;
    overflow: hidden;
}
}

It should works.

它应该工作。

I've Found my answer.

我找到了答案。

It was a JS script that automaticly finds the height of the window and sets that height to a given class.

这是一个JS脚本,可以自动查找窗口的高度并将该高度设置为给定的类。

But, that wasn't the whole solution. The height's where better, and weren't all over the place as it was before when I applied height:100%; to the html, body and section.

但是,这不是整个解决方案。高度是更好的地方,而不是像我之前应用身高的那样:100%;到HTML,正文和部分。

I made media queries, on the max-height per phone size, so it was expand beyond the intended sections.

我在每个手机尺寸的最大高度上进行了媒体查询,因此它超出了预期的部分。

The JS solution is:

JS解决方案是:

// On document ready set the div height to window
$(document).ready(function(){ 

    // Assign a variable for the application being used
    var nVer = navigator.appVersion;
    // Assign a variable for the device being used
    var nAgt = navigator.userAgent;
    var nameOffset,verOffset,ix;


    // First check to see if the platform is an iPhone or iPod
    if(navigator.platform == 'iPhone' || navigator.platform == 'iPod'){
        // In Safari, the true version is after "Safari" 
        if ((verOffset=nAgt.indexOf('Safari'))!=-1) {
          // Set a variable to use later
          var mobileSafari = 'Safari';
        }
    }

  //===== FULL HEIGHT =====\\

    // If is mobile Safari set window height +60
    if (mobileSafari == 'Safari') { 
        // Height + 60px
        $('.full-height').css('height',(($(window).height()) + 60)+'px');
    } else {
        // Else use the default window height
        $('.full-height').css({'height':(($(window).height()))+'px'});  
    };


});

// On window resize run through the sizing again
$(window).resize(function(){
    // If is mobile Safari set window height +60
    if (mobileSafari == 'Safari') { 
        // Height + 60px
        $('.full-height').css('height',(($(window).height()) + 60)+'px');
    } else {
        // Else use the default window height
        $('.full-height').css({'height':(($(window).height()))+'px'});  
    };

 /* //===== HALF HEIGHT =====\\

    // If is mobile Safari set window height +60
    if (mobileSafari == 'Safari') { 
        // Height + 60px
        $('.half-height').css('min-height',(($(window).height() /2) + 60)+'px'/2);
    } else {
        // Else use the default window height
        $('.half-height').css({'min-height':(($(window).height()/2)  )+'px'});  
    };

// On window resize run through the sizing again
$(window).resize(function(){
    // If is mobile Safari set window height +60
    if (mobileSafari == 'Safari') { 
        // Height + 60px
        $('.half-height').css('min-height',(($(window).height()/ 2)  + 60)+'px');
    } else {
        // Else use the default window height
        $('.half-height').css({'min-height':(($(window).height()/ 2) )+'px'});  
    };
});

  //===== DOUBLE HEIGHT =====\\

    // If is mobile Safari set window height +60
    if (mobileSafari == 'Safari') { 
        // Height + 60px
        $('.half-height').css('min-height',(($(window).height()* 2)  + 60)+'px');
    } else {
        // Else use the default window height
        $('.half-height').css({'min-height':(($(window).height()* 2)  )+'px'}); 
    };


});

// On window resize run through the sizing again
$(window).resize(function(){
    // If is mobile Safari set window height +60
    if (mobileSafari == 'Safari') { 
        // Height + 60px
        $('.half-height').css('min-height',(($(window).height()* 2)  + 60)+'px');
    } else {
        // Else use the default window height
        $('.half-height').css({'min-height':(($(window).height()* 2) )+'px'});  
    };*/
});

And the CSS (used SCSS) solution is:

CSS(使用SCSS)解决方案是:

//IPHONE&SAMSUNG PLUS
@media (max-height: 736px) {
  .full-height{
    max-height:736px;
  }
  .introductie-mobile {
  height: 1200px !important;
  max-height: 1200px;
  }
}
//IPHONE 6/7/8
@media (max-height: 667px) {
  .full-height{
    max-height:667px;
  }
  .introductie-mobile {
    height: 1200px !important;
    max-height: 1200px;
  }

}
//IPHONE %
@media (max-height: 568px) {
  .full-height{
    max-height:568px;
  }
  .introductie-mobile {
    height: 1200px !important;
    max-height: 1200px;
  }
}

The height of the top black <div class="video-section"> is full height on any device including iPhone. So height in and of itself is not the problem.

在包括iPhone在内的任何设备上,顶部黑色

的高度都是全高。所以身高本身并不是问题所在。

On other devices however, the position of the next <div class="sign-up-banner"> changes dynamically so that it moves with a parallax effect as you scroll down. Once you're fully past the top black <div class="video-section"> the entire second <div class="sign-up-banner"> is fully visible. This is being done with the javascript code. For whatever reason, this javascript is not running on the iPhone.

但是,在其他设备上,下一个

的位置会动态变化,以便在向下滚动时以视差效果移动。一旦你完全超过顶部的黑色

,整个第二个

就完全可见了。这是使用javascript代码完成的。无论出于何种原因,这个javascript都没有在iPhone上运行。

Some of the CSS applied to the <form> within the <div id="coming-soon"> is still applied which leaves you with the div stuck behind the first one.

应用于

中的

的一些CSS仍然会被应用,这使得div停留在第一个之后。

You can reverse this with the following css:

您可以使用以下css撤消此操作:

.sign-up-banner{
    position: static;
    height: auto;
}

#mc_embed_signup form{
    position: static !important;
    -ms-transform: none; /* IE 9 */
    -webkit-transform: none; /* Chrome, Safari, Opera */
    transform: none; 
}

You could wrap that in a media query so it only applies to a particular screen. To get it to apply for the iPhone.

您可以将其包装在媒体查询中,以便它仅适用于特定屏幕。要让它申请iPhone。

@media only screen 
  and (min-device-width: 320px) 
  and (max-device-width: 568px)
  and (-webkit-min-device-pixel-ratio: 2) {
    //insert your css here
}

That will apply css to a iPhone 4 and 4s. It's not guaranteed to not apply to other devices, but css cannot target particular devices so it's the best we've got. You can see media queries which target other devices including other iPhone models at https://css-tricks.com/snippets/css/media-queries-for-standard-devices/.

这将适用于iPhone 4和4s的CSS。它不能保证不适用于其他设备,但css无法针对特定设备,因此它是我们所拥有的最佳设备。您可以在https://css-tricks.com/snippets/css/media-queries-for-standard-devices/上查看针对其他设备(包括其他iPhone型号)的媒体查询。
