IOS(iphone)上的高度不正常

时间:2017-11-16 16:02:20

标签: html ios css iphone responsive

我在codepen上创建了this网站。在尝试使其对所有平台做出响应时,我遇到了一个问题。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)。

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。

我已尝试删除显示大部分页面的video-section,但eind部分只是空白。

我已经尝试添加max-height,这确实揭示了其他一些内容,但看起来好像页面在IOS上不会更高,所以我&#39 ; m仍然限于一个可以使用的空间。它似乎也不是一个合适的解决方案。

我尝试更改position,但无济于事。

似乎高度不适合在IOS上运作

任何人都可以帮我弄清楚为什么会这样吗?



var $animation_elements = $('.animation-element');
var $window = $(window);

function check_if_in_view() {
  var window_height = $window.height();
  var window_top_position = $window.scrollTop();
  var window_bottom_position = (window_top_position + window_height);

  $.each($animation_elements, function() {
    var $element = $(this);
    var element_height = $element.outerHeight();
    var element_top_position = $element.offset().top;
    var element_bottom_position = (element_top_position + element_height);

    //check to see if this current container is within viewport
    if ((element_bottom_position >= window_top_position) &&
      (element_top_position <= window_bottom_position)) {
      $element.addClass('in-view');
    } else {
      $element.removeClass('in-view');
    }
  });
}

$window.on('scroll resize', check_if_in_view);
$window.trigger('scroll');

与IOS无关,这是响应性的问题。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。

只需将所有section身高设置为height: 100vh

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

它应该有用。

我找到了答案。

这是一个JS脚本,可以自动查找窗口的height并将该高度设置为给定的类。

但是,这不是整个解决方案。高度是更好的地方,而不是像我之前将height:100%;应用到html,正文和部分之前那样。

我按每个电话尺寸的max-height进行了媒体查询,因此扩展到预定的部分之外。

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

});

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;
  }
}

答案 2 :(得分:2)

任何设备(包括iPhone)的顶部黑色<div class="video-section">的高度为全高。所以身高本身并不是问题。

然而,在其他设备上,下一个<div class="sign-up-banner">的位置会动态变化,以便在向下滚动时以视差效果移动。一旦完全超过顶部的黑色<div class="video-section">,整个第二个<div class="sign-up-banner">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。

应用于<form>中的<div id="coming-soon">的某些CSS仍然会被应用,这会让您将div留在第一个后面。

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; 
}

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
}

这会将css应用于iPhone 4和4s。不保证不适用于其他设备,但css无法定位特定设备,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/看到针对其他设备(包括其他iPhone型号)的媒体查询。
