<li> will not take 100% height of the parent <ul>

Question

I have a <ul> with several <li> items in it all in a single row. The <li> has a nested <span> and an <img> . The <img> height is all the same across all items. But the <span> items contain text which can span on a single line or two lines (depends on text).

I have tried appying display:block , float:left , height:100% , and few other suggestions I found, but the shorter <li> items will not take the same height as the taller <li> items. So I am left with a space below the shorter <li> items. Anyone has any suggestions on this?

Answer 1

In this case, when you set height:100% it isn't inheriting any height from its parent. If you want the list items to have 100% height of the div #wrapper, then you should set the ul's height to 100% and set a height on the div #wrapper in pixels or em's:

#wrapper {
    background: transparent;
    width: 350px;
    color: white;
    height:250px;
}
#wrapper ul {
    list-style-type: none;
    display: block;
    float: left;
    background: green;
    height:100%;
}

If you'd rather have it stretch to the full height of the browser window, then you need to set the height of html, body in your css to 100%, and then all of the elements down to the li (html, body, div#wrapper, ul.list, and li) must have 100% height:

html, body{
    height:100%;
    margin:0;
    padding:0;
}
#wrapper {
    background: transparent;
    width: 350px;
    color: white;
    height:100%;
}
#wrapper ul {
    list-style-type: none;
    display: block;
    float: left;
    background: green;
    height:100%;
}

An easy fix is to add display:table on your ul element. The hieght will align with the content.

如果你改变容器ul的list-style-position ，也许它会修复
