Javascript 如何保持滑块两侧的边距？

我为我的网站制作了一个图像滑块。我想在它的右边和左边都有98px的边距，这样滑块就好像在网页的中间。怎么做

现在我知道了：

左边距：98px； 右边距：98px可以在两侧保持98像素的边距。但在我的情况下，它不起作用

main.php文件：

    </div>
<div id="gallery">
<!--code for slider begins-->
<div id="slide_frame_setup">
<p id="slider_paragraph">The slider contains my recently taken photos.

如果我理解得很好，您可以尝试以下方法：

.slide{
    width: Calc(100% - 196px); /*196px means both sides (left 98px and right 98px)*/
    margin: 0 auto;
}

你能把你的代码和一些图片放在一起吗？我解决了：。幻灯片img{宽度：121.5%；高度：100%；}好的，调整页面大小时它会保持比例；）

.slide{
    width: Calc(100% - 196px); /*196px means both sides (left 98px and right 98px)*/
    margin: 0 auto;
}
