当元素离开屏幕时如何修复窗口正在调整大小

Question

当我在做一个项目时，我想给我的页面添加一个效果。所以我把元素放在屏幕外。但是在运行代码时，窗口会通过滚动条调整大小，这对移动用户来说很困难

这是我为效果使该元素脱离屏幕的代码。

    <!--html-->
    <div class="full-view cont" id="desc">
       <h1>What is IoT?</h1>
       <br /><br /><br /><br />
       <section>
       <div class="half-view">
           <img src="https://www.webyot.com/assets/site/img/iot.png" alt="" class="half-img"/>
       </div>
       <div class="half-view">
          <p class="p">
          The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
               </p>
            </div>
        </section>
    </div>

在 js 中我是这样做的

//js
  $(".cont:nth-child(even)").animate({left:"-100%"},1);

我想在不调整窗口大小的情况下隐藏所有这些 div，但它确实带有一些不整洁的滚动条。有人知道怎么解决吗？

这是完整的代码

//js
var conts;
window.onbeforeunload = () => {
  window.scrollTo(0, 0);
}
$(document).ready(() => {
  $(document).scrollTop(0);
  $(".full-view").css("height", window.innerHeight + "px");
  $(".p").css("max-height", window.innerHeight - 150 + "px");
  /*if($(".full-view").hasChild("half-view")) {
    $(".full-view").css({"display":"grid"});
  }*/
  $("body").prepend(`<nav class='main-nav'><ul><li> HOME </li><li> USAGE </li><li> ABOUT </li></ul><button class='burger fas fa-bars' value='false'></button></nav><div class='ddlsup full-view'></div><ul class='ddl full-view' ><i class='fas fa-times-circle' onclick="$('.burger').trigger('click')" style="
    position: relative;
    left: 90%;
    font-size: 20px;

  $('body').append(`<footer class='main-footer' style="height:` + window.innerHeight + `px">

Answer 1

你可以试试

.cont {
   overflow-x: hidden;
}

对于父元素

https://developer.mozilla.org/de/docs/Web/CSS/overflow

Answer 2

将 css 属性 overflow:hidden 提供给要放置在屏幕外以防止滚动条的子元素的父 div
