CSS 挫折：如何将不同宽度的浮动图像置于 LI 标签内？

发布于 2024-09-14 19:43:37 字数 504 浏览 2 评论 0原文

我正在开发一个具有 javascript 图像旋转器的网页，但它需要能够处理不同尺寸的图像。

我用作基础的代码在包含图像的浮动 LI 外部有一个 DIV，但无论我尝试什么，我似乎都无法使图像全部居中。唯一居中的是宽度为 800 像素的那一个。

我有一种感觉，这与浮动、位置或显示有关，但我已经搞砸了几个小时了，但没有运气。

这是我的网站：

这是我借用图像旋转器代码的地方： http://www.serie3.info/s3slider/ （代码）http://www.serie3.info/s3slider/demonstration.html（演示）

这也有效（在 Firefox 和 Safari 中，还没有尝试过 IE）。另存为 .html 作为示例。

This works as well (In Firefox and Safari, haven't tried IE). Save as a .html for an example.

添加：

left: 0;
padding: 0;

到 #slider1Content 样式。

然后从 .slider1Image 样式中删除 float: left; 。

请注意，源 CSS 包含此警告：在多个维度上“重要的是与图像宽度相同”。由于此 CSS 并未针对每个图像调整大小，因此每张图片周围都会有白色边距。

如果您希望动态重置这些关键维度（我认为没有这个网站看起来还不错），那么这是一个单独的问题，之前已经在这里回答过。

Add:

left: 0;
padding: 0;

to the #slider1Content style.

Then delete the float: left; from the .slider1Image style.

Note that the source CSS contains this warning: "important to be same as image width" on several dimensions. Since this CSS isn't sized for each image, you'll have that white margin around each picture.

If you desire to reset those key dimensions dynamically (I think the site looks OK without this), then that is a separate question that has been answered here on SO before.
