使用浮动图像时,HTML列表不垂直对齐 [英] HTML List isn't vertically aligned when using floating images
问题描述
我有一个包含标题,文本和图片的列表,有时,当没有足够的文本时,我的列表开始破坏,即。该列表开始嵌套本身。
< ul>
< li>< img style =float:left>< h3> title< / h3> ...这里有一些文字< / li>
< li>< img style =float:left>< h3> title< / h3> ...这里有一些文字< / li>
< li>< img style =float:left>< h3> title< / h3> ...这里有一些文字< / li>
< / ul>
我有一个例子:
http://jsfiddle.net/2z6Zn/246/
img {float:left; margin-right:0.1em;}
< ul& < li> < h3>照片< / h3> < img src =http://commons.cathopedia.org/w/images/commons/thumb/f/fe/Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG/>照片旁边的一些文字< / li> < li> < h3>照片< / h3> < img src =http://commons.cathopedia.org/w/images/commons/thumb/f/fe/Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG/>照片旁边的一些文字< / li> < li> < h3>照片< / h3> < img src =http://commons.cathopedia.org/w/images/commons/thumb/f/fe/Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG/>照片旁边的一些文字< / li>< / ul>
你缺少的部分是清除 float
s。使用:
li:{
content:'';
display:block;
clear:both;
}
现在您将删除嵌套。
请注意,使用浮动容器时,应始终
清除
从而在调用时创建新的块
格式化上下文。否则您将看到
不可预测的行为。
下面的修改演示:
img {float:left; margin-right:0.1em;} li:after {content:'';显示:block; clear:both;}
< ul>< li> ;< h3>照片< / h3>< img src =http://commons.cathopedia.org/w/images/commons/thumb/f/fe/Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG/> ;照片旁边的一些文字< / li>< li>< h3>照片< / h3>< img src =http://commons.cathopedia.org/w/images/commons/thumb/f/fe /Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG/>照片旁边的一些文字< / li>< li>< h3>照片< / h3>< img src =http://commons.cathopedia.org/w/images/commons/thumb/f/fe /Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG/> < / ul>
旁边的一些文字
I have a list with titles, text and images, and sometimes, when there is not enough text, my lists start breaking, ie. the list starts nesting itself.
<ul>
<li><img style="float:left"><h3>title</h3> ... some text here</li>
<li><img style="float:left"><h3>title</h3> ... some text here</li>
<li><img style="float:left"><h3>title</h3> ... some text here</li>
</ul>
I have an example here:
http://jsfiddle.net/2z6Zn/246/
img {
float: left;
margin-right: 0.1em;
}
<ul>
<li>
<h3>photo</h3>
<img src="http://commons.cathopedia.org/w/images/commons/thumb/f/fe/Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG" />some text next to the photo
</li>
<li>
<h3>photo</h3>
<img src="http://commons.cathopedia.org/w/images/commons/thumb/f/fe/Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG" />some text next to the photo
</li>

<h3>photo</h3>
<img src="http://commons.cathopedia.org/w/images/commons/thumb/f/fe/Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG" />some text next to the photo

</ul>
What's the best way to fix this?
The part you are missing is to clear the float
s. Use this:
li:after {
content: '';
display: block;
clear: both;
}
and now you will have removed the "nesting".
Note that while using floating containers, you should always
clear
them before the next container that follows thereby creating a fresh block formatting context as it is called. Otherwise you will see unpredictable behavior.
Revised demo below:
img {
float: left;
margin-right: 0.1em;
}
li:after {
content: '';
display: block;
clear: both;
}
<ul>
<li>
<h3>photo</h3>
<img src="http://commons.cathopedia.org/w/images/commons/thumb/f/fe/Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG" /> some text next to the photo
</li>
<li>
<h3>photo</h3>
<img src="http://commons.cathopedia.org/w/images/commons/thumb/f/fe/Carnevale_di_Venezia.JPG/250px-Carnevale_di_Venezia.JPG" /> some text next to the photo
