问题描述
我正在使用图片,而且遇到了长宽比问题。
< img src =big_image .jpgwidth =900height =600alt =/>
可以看到, height
code> width 。我为图片添加了CSS规则:
img {
max-width:500px;
}
但 big_image.jpg
,我收到 width = 500
和 height = 600
。
解决方案
img {显示:block; max-width:230px; max-height:95px; width:auto; height:auto;} < p&原始为400x400像素,但应通过CSS调整大小:< / p>< img width =400height =400src =http://i.stack.imgur.com/aEEkn.png> ;
如果指定区域太大, (作为下降,它不会放大图像)。
I am working with images, and I ran across a problem with aspect ratios.
<img src="big_image.jpg" width="900" height="600" alt="" />
As you can see, height
and width
are already specified. I added CSS rule for images:
img {
max-width:500px;
}
But for big_image.jpg
, I receive width=500
and height=600
. How I can set images to be re-sized, while keeping their aspect ratios.
解决方案
img {
display: block;
max-width:230px;
max-height:95px;
width: auto;
height: auto;
}
<p>This image is originally 400x400 pixels, but should get resized by the CSS:</p>
<img width="400" height="400" src="http://i.stack.imgur.com/aEEkn.png">
This will make image shrink if it's too big for specified area (as downside, it will not enlarge image).
