Question

我试图做拇指并保持其原始比例。拇指的div应该有宽度：189px和高度179px。但现在，拇指本身的高度更大，比例也不同。怎么做？

我正在尝试这个：

＆＃13;

<div class="thumbnail image-thumbnail">
  <a href="someurl"><img src="thumb_src" class="thumb"/></a>
  </div>

＆＃13;

.thumbnail {
    background-color: #fff;
    border: 1px solid #ddd;
    border-radius: 4px;
    display: block;
    line-height: 1.42857;
    margin-bottom: 20px;
    padding: 4px;
    transition: all 0.2s ease-in-out 0s;
}
.image-thumbnail {
    border: 0 none;
    float: left;
    margin-right: 1%;
    margin-top: 10px;
    padding: 0 !important;
    width: 19.2%;
}
.thumb {
    display: block !important;
    max-height: 178px;
    min-height: 178px;
    min-width: 100%;
  }

＆＃13;

$max_width = 289;
$path = $_REQUEST['path'];
list($orig_width, $orig_height) = getimagesize($path);

$width = $orig_width;
$height = $orig_height;

# wider
if ($width > $max_width) {
$height = ($max_width / $width) * $height;
$width = $max_width;
}
$image = Image::factory ( $path, 'GD' );
$image->resize($width,$height)->save($tmbPath,100);

除非你真的想要do this in php，否则你可以使用css并将图片的max-width和max-height属性设置为最大尺寸，width和height到auto以保留宽高比：

img{
    max-width:189px;
    max-height:179px;
    width: auto;
    height: auto;
}

＆＃13;

img{
    max-width:180px;
    max-height:179px;
    width: auto;
    height: auto;
}

＆＃13;
