将最后一个li扩展到ul的剩余宽度？ [英] Extend last li to remaining width of a ul?

问题描述

我已经困惑了一段时间了。这里是我现在：

I have been puzzled about this for a while now. Here is what i have now:

-------------------------------------------------------------------------------
|                   |                  |                     |
|       Item 1      |      Item 2      |      Last item      |
|                   |                  |                     |
-------------------------------------------------------------------------------

在这里，最后一个li只占用ul的一部分。我需要它看起来像这样：

There, the last li is only taking up part of the ul. I need it to look like this:

-------------------------------------------------------------------------------
|                   |                  |                                      |
|       Item 1      |      Item 2      |              Last item               |
|                   |                  |                                      |
-------------------------------------------------------------------------------

我不能使用Javascript（或Jquery）。
我不想设置每个li的宽度，因为文本大小可以变化，我不知道将有多少li。我可能有5或3。'

I can not use Javascript (or Jquery). I do not want to set the width of each li, since the text size could vary, and i do not know how many li's there will be. I might have 5 or 3.'

我该如何做到这一点？谢谢。

How would i accomplish this? Thanks.

这里是一些jsfiddle我的一些代码。我需要更浅的颜色来扩展ul​​的其余部分。 JSFIDDLE

Here is a jsfiddle with some of my code. I need the lighter color to expand the rest of the ul. JSFIDDLE

推荐答案

最后一个元素的框模型会扩展到这些浮动的列表项后面（即使内容没有） 。 overflow：hidden 将阻止此行为;

The last element's box model will then extend behind these floated list items (even though the content doesn't). overflow:hidden will prevent this behaviour; the box model will begin when the last floated item ends, as if the floated items were still in the natural flow of the page.

ul, li{
    margin:0;
    padding:0;
    
    list-style-type:none;
}

ul li{
    display: block;
    float:left;
}

ul li:last-child{
    background-color: #ddd;

    float:none;
    overflow:hidden;
}

<ul>
    <li>Item</li>
    <li>Item</li>
    <li>I will extend to the end of the page.. No matter how far. I will also not drop beneath my previous items, even if the text in here requires me to span over multiple lines.</li>    
</ul>
