Here you can see a white gap when I scroll right我希望删除该间隙，这是我的代码:

<div class="top fullscreen background parallax img-responsive" id="inicio" style="background-image:url('images/fondos/<? echo rand(1,5); ?>.png');" " data-img-width="1920" data-img-height="1080" data-diff="250">

                <h1>Bedif</h1>
                <!-- <img src="images/bedif636x144.png" class="col-sm-3 col-md-6 offset-md-6" style="margin-left: auto;  margin-right: auto;"> -->
                    <? if($this->session->flashdata('error')){?>

更新

试试这个

body{
 overflow-x:hidden;
}

这应该可以让我知道

旁注

在你的 html 中，你的内联样式有一个小错误，我在下面突出显示了它

<div class="top fullscreen background parallax img-responsive not-overflow" id="inicio" style="background-image: url(&quot;images/fondos/3.png&quot;); background-attachment: fixed; background-size: 1991.11px 1120px; background-position: 50% -125px;" "="" data-img-width="1920" data-img-height="1080" data-diff="250">

如果你照顾 -125px;"你有 "=""
