javascript - slider 坏移

我有一个正在使用的 slider ，每当我单击下一个或上一个按钮时，它都会以覆盖我网站某些元素的方式移动。我相信#mask 中的问题，我尝试对其进行一些更改但没有任何区别，是否知道它是否导致问题或其他问题？有什么解决办法吗？

代码:

我修改了你的html:

                </div>
                <div id="item3" class="item">
                    <div class="content">
                        <img id="image1" src="http://placehold.it/350x150" alt="slot2" />

                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
</body>

这是CSS:

body {
    margin: 0;
}
#wrapper {
    background-color: blue;
    padding: 20px 0;
}

#slider-container {
    padding: 20px 50px;
    height: 350px;
    background-color: white;
    overflow: hidden;
    position: relative;
}

.slider-view-area {
    overflow: hidden;
}

#nav p {
    position: absolute;
    top: 100px;
    cursor:pointer;
    color:grey;

}
#prev {
    left: 20px;
    font-size: 30px;
}
#next {
    right: 20px;
    font-size: 30px;
}
#mask {
    width: 50000px;
    height: 100%;
    background-color: white;
}
.item {
    width: 1200px;
    height: 100%;
    float: left;
    background-color: white;
}
.content img {
    height: 100px;
    width: 17%;
    float:left;
    margin-right: 10px;
    margin-bottom: 10px;
}
.content {
    width: 50%;
    height: 220px;
    top: 20%;
    margin: auto;
    background-color: white;
    position: relative;
}
.content a {
    position: relative;
    top: -17px;
    left: 170px;
}
.selected {
    background: #fff;
    font-weight: 700;
}
.clear {
    clear:both;
}

我删除了导航元素周围的 h1 标签，因为您不应该使用标题标签来进行显示更改，例如使图标看起来更大。为此，您应该使用 css。在这种情况下，h1 标签在语义上是不正确的，因为导航元素不是主标题。

我只是去快速修复一下。但如果您想让 slider 成为您页面中的一个独立组件，那么它应该是您应该采取的方向。
