Question

我正在制作一个应用程序，其中我有一个幻灯片进/出菜单。显示此菜单时，我希望它以两行显示图像。由于有很多图像，我想要一个水平滚动来浏览它们以及箭头。

我的问题是我无法以水平方式将这些图像排成两行。它们一直以垂直方式出现。

目前，当我添加更多图像时，右侧的箭头消失了，当我滚动到最后它再次显示时。我不知道为什么我没有移动其他元素就无法确定滚动区域。

var step = {};
var stepsOpen = false;

function onHandleClick() {
    if (stepsOpen) {
        document.getElementsByClassName("StepMenu")[0].setAttribute("style", "top: -77px;");
        document.getElementsByClassName("Handle")[0].setAttribute("style", "top: 102px;");
    } else {
        document.getElementsByClassName("StepMenu")[0].setAttribute("style", "top: 102px;");
        document.getElementsByClassName("Handle")[0].setAttribute("style", "top: 281px;");
    }
    stepsOpen = !stepsOpen;
}

我刚刚为CSS中的图像添加了float：left。这对你有帮助。这是我的小提琴链接..

https://jsfiddle.net/b6jpkdhk/

img {
    width: 97px;
    height:55px;
    background-image: url('../res/image/tuna.jpg');
    margin-left: 12.5px;
    margin-right: 12.5px;
    margin-bottom: 31px;
    display: table-cell;
    float:left;
}
