Question

我为我的网站制作了一个图片滑块。我想在它的右侧和左侧都有98px的边距，这样滑块似乎在网页中间。怎么做？

现在我知道了：

保证金左：98px; margin-right：98px; 可以保持双方98px的保证金。但就我而言，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，你可以尝试这样的事情：

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

如何保持滑块两侧的边距？
