问题描述
I am working with images, and I ran into 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 a CSS rule for images:
img {
max-width: 500px;
}
But for big_image.jpg
, I receive width=500
and height=600
. How do I set images to be re-sized, whilst 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).
