如何在 div 中动态添加更多宽度？

Question

我用 jQuery UI 创建了一个时间线。对于我的问题：如果我用图像和文本添加更多年份，如何在该 div 内动态添加更多空间？在这种情况下：#timline。当我添加更多年份时会出现问题，我需要更改时间线内的宽度。它设置为超过 3000 像素。我怎样才能防止这种情况？这是一个fiddle 的案例

Javascript

$(function () {
    var scrollPane = $("#timeline-container"),
        scrollContent = $("#timeline");

    var scrollbar = $("#slider").slider({
        slide: function (event, ui) {
            if (scrollContent.width() > scrollPane.width()) {
                scrollContent.css("margin-left", Math.round(
                ui.value / 100 * (scrollPane.width() - scrollContent.width())) + "px");
            } else {
                scrollContent.css("margin-left", 0, "left", 0);
            }
        }
    });

给你

#timeline {
  display: -webkit-inline-box;
  overflow-y: hidden;
  width: auto;
  height: 480px;
  padding: 0px;
}

并为 Firefox 添加显示属性，例如 显示：-moz-inline-box； 或者我相信的类似的东西
