图像无拉伸或裁剪 [英] Image No Stretch or crop

问题描述

我的问题很简单。假设我有两个矩形图像。第一个是200px宽，100px高，第二个是100px宽和200px高。

My question is simple. Let's say I have two rectangular images. The first is 200px wide and 100px tall, and the second is 100px wide and 200px tall.

我想显示具有恒定宽度/高度的图像，例如150px乘150px而不拉伸图像以适合：

I want to display the images with a constant width/height, e.g. 150px by 150px without stretching the images to fit:

我不介意在图像周围有空格/填充。问题是图像可以是任何宽度和高度，我想将它们限制在一个方框而不拉伸它们。

I don't mind having whitespace/padding around the images. The problem is that the images could be of any width and height, and I want to limit them to a square box without stretching them.

以下CSS将图像拉伸到适合150px乘150px：

The following CSS stretches the images to fit to 150px by 150px:

img {
    width: 150px;
    height: 150px;
}

最优选的解决方案是CSS，即使我需要更多标记。 JS / jQuery也没关系。

The most preferable solution is CSS, even if I need a little more markup. JS/jQuery is okay as well though.

推荐答案

怎么样：

img {
    max-height:150px;
    max-width:150px
}

要完成关于制作的第二个问题更小的图像更大，你可以用jQuery做。如果您事先知道照片方向并且对这些图像应用了不同的css类，那么CSS可以工作......但是这样可以工作，然后您不再需要CSS最大宽度的东西了。

To achieve your 2nd question on making smaller images bigger, you can do with jQuery. CSS could work if you knew the photo orientation before hand and applied a different css class to those images... But this will work and then you don't need the CSS max-width stuff any more.

<div class="container"><img src="images/DSC_0470.JPG" alt="Rad Image" /></div>

<script>
    $(document).ready(
        function () {
            $('.container img').each(
            function () {
                var theWidth = $(this).width();
                var theHeight = $(this).height();
                if (theWidth < theHeight) {
                    $(this).height(150);
                }
                else {
                    $(this).width(150);
                }

            });
        });</script>
