img在div中不按百分比调整大小

I have this code but the image stays at its original size.

我有这个代码,但图像保持原始大小。

                <div style="margin: 10px; align: center;">
                    <img height="40%" src="data:image/jpeg;base64,{{ photo }}" />
                </div>

If I remove the div, then it resizes perfectly though.

如果我删除div,那么它会完美地调整大小。

What do I need to do to make it resize correctly even inside the div?

即使在div内,我还需要做些什么才能正确调整大小?

Thanks

The image is suppose to take 40% of your div's size, but your div is empty and it does not have a size specified, this means by default your div's size will be set to auto(meaning it will resize based on content). thats why the image does not resize, do this:

图像假设占用div的大小的40%,但你的div是空的并且没有指定大小,这意味着默认情况下你的div的大小将设置为auto(意味着它将根据内容调整大小)。这就是图像不调整大小的原因,请执行以下操作:

<div style="margin: 10px; align: center; width:500px; height:500px;">
            <img height="40%" src="data:image/jpeg;base64,{{ photo }}" />
            </div>

Here is a demo:

这是一个演示:

<div style="margin: 10px; align: center; width:500px; height:500px;">
    <img height="40%" src="http://www.cypresspa.com/images/img/home-1-bg-3.jpg" />
</div>
