更改 JQM 面板的宽度

Question

我想弄清楚如何更改 JQM 面板动画的宽度。我可以更改面板中内容的宽度，但动画仍然以我不知道如何更改的预定义宽度打开。

这是我尝试过的，它改变了内容。

.ui-panel {
    width: 150px;
}

我查看了 JQM 文档，但没有找到解决方案。希望得到帮助:-)

好吧，实际上，我找到了这个脚本，但是......只有当我将所有@left-panel-width 更改为实际宽度为 150 像素时？为什么@left-panel-width 不起作用？

@left-panel-width: 100px;
@right-panel-width: 100px;

.ui-panel {
    width: @left-panel-width;
}

.ui-panel.ui-panel-position-right {
    width: @right-panel-width;
}

.ui-panel.ui-panel-closed {
    width: 0;
}

.ui-panel-position-left {
    left: -@left-panel-width;
}

.ui-panel-animate.ui-panel-position-left.ui-panel-display-overlay, .ui-panel-animate.ui-panel-position-left.ui-panel-display-push {
    -webkit-transform: translate3d(-@left-panel-width, 0, 0);
    -moz-transform: translate3d(-@left-panel-width, 0, 0);
    transform: translate3d(-@left-panel-width, 0, 0)
}

.ui-panel-position-right {
    right: -@right-panel-width
}

.ui-panel-animate.ui-panel-position-right.ui-panel-display-overlay, .ui-panel-animate.ui-panel-position-right.ui-panel-display-push {
    -webkit-transform: translate3d(@right-panel-width, 0, 0);
    -moz-transform: translate3d(@right-panel-width, 0, 0);
    transform: translate3d(@right-panel-width, 0, 0)
}

}

提前致谢 ;-)

在使用 jQuery Mobile 时，如果你想覆盖原来的 CSS，你必须使用 !important。还因为 jsFiddle 不支持 CSS 变量，所以一切都是硬编码的。

CSS：

.ui-panel {
    width: 50px !important;
}

.ui-panel.ui-panel-position-right {
    width:  50px !important;
}

.ui-panel.ui-panel-closed {
    width: 0;
}

.ui-panel-position-left {
    left: 50px !important;
}

.ui-panel-animate.ui-panel-position-left.ui-panel-display-overlay, .ui-panel-animate.ui-panel-position-left.ui-panel-display-push {
    -webkit-transform: translate3d(50px, 0, 0) !important;
    -moz-transform: translate3d(50px, 0, 0) !important;
    transform: translate3d(50px, 0, 0) !important;
}

.ui-panel-position-right {
    right: 50px !important;
}

.ui-panel-animate.ui-panel-position-right.ui-panel-display-overlay, .ui-panel-animate.ui-panel-position-right.ui-panel-display-push {
    -webkit-transform: translate3d(50px, 0, 0) !important;
    -moz-transform: translate3d(50px, 0, 0) !important;
    transform: translate3d(50px, 0, 0) !important;
}

.ui-panel-content-fixed-toolbar-position-left.ui-panel-content-fixed-toolbar-open, .ui-panel-content-wrap-position-left.ui-panel-content-wrap-open, .ui-panel-dismiss-position-left.ui-panel-dismiss-open {
    left: 50px !important;
    right: 50px !important;

查看此页面http://demos.jquerymobile.com/1.3.0/docs/examples/panels/panel-styling.html#demo-page——查看源代码...上面写着“

面板样式

    <p>In this demo we show you how to:</p>

    <ul>
        <li>Change the width of a panel.</li>
        <li>Create a panel navmenu with listviews and collapsibles.</li>
        <li>Change the shadow of a reveal menu so it is on top of the list items.</li>
        <li>Set a background image for a page that contains a panel.</li>
        <li>Give the page a responsive layout with CSS columns.</li>
    </ul>

页面源代码顶部有具体说明。他们为我工作。
