自动居中并保持Div。中的图像的纵横比 [英] Auto Center and Keep Aspect Ratio of Image in Div
问题描述
我试图使一个图像在一个div中心,同时保持宽高比 - 我使用这个代码,但不知何故,它不会对齐中心(顶部/底部中心)的项目。如果可能只使用CSS。
图片的大小不知道,因为它使用了最大宽度!
JSfiddle: http://jsfiddle.net/L41wpza6/2/
#imageHolder {
width:400px;
height:400px;
line-height:400px;
background-color:#CCCCCC;
}
#imageHolder img {
max-width:100%;
max-height:100%;
display:block;
margin:0 auto;
vertical-align:middle;
}
JSFiddle - DEMO
您应该使用 display:inline-block; 到
#imageHolder img
到vertical-align中间。
CSS display inline-block属性允许元素像内联元素一样流动,但是尊重属性(如宽度),如块元素,并且您可以使用display Inline-block设置vertical-align中间。
HTML :
< img src =http://www.discoverjb.com/wp-content/uploads/2014/07/IMG_1399.jpg>
< / div>
CSS:
#imageHolder {
width:400px;
height:400px;
line-height:400px;
background-color:#CCCCCC;
}
#imageHolder img {
max-width:100%;
max-height:100%;
display:inline-block; / *而不是display:block; * /
margin:0 auto;
vertical-align:middle;
}
I m trying to center an image in a div while keeping the aspect ratio - I m using this code but somehow its not aligning the item in the center (top/bottom center). If possible using only CSS.
The size of the image is not known since its using max widths!
JSfiddle: http://jsfiddle.net/L41wpza6/2/
#imageHolder {
width: 400px;
height: 400px;
line-height: 400px;
background-color:#CCCCCC;
}
#imageHolder img {
max-width: 100%;
max-height:100%;
display: block;
margin: 0 auto;
vertical-align: middle;
}
Any help is appreciated! I am not sure what I am missing to make this work.

You should use display: inline-block;
to #imageHolder img
to vertical-align middle.
CSS display inline-block property allows elements to flow like inline elements but respect properties, such as width, like block elements and you can use display Inline-block to set vertical-align middle.
HTML:
<div id="imageHolder">
<img src="http://www.discoverjb.com/wp-content/uploads/2014/07/IMG_1399.jpg">
</div>
CSS:
#imageHolder {
width: 400px;
height: 400px;
line-height: 400px;
background-color:#CCCCCC;
}
#imageHolder img {
max-width: 100%;
max-height:100%;
display: inline-block; /* Instead of display: block; */
margin: 0 auto;
vertical-align: middle;
}
