为flex类型的div容器设置最小和最大宽度？

Question

I am using a flex container and setting the min and max for same element like this:

.title-image-container {
    display: flex;
}

div.amz-image-container {
    min-width: 130px;
    max-width: 130px;
}
.amz-image-container>a>img {
   width: 100%;
}

Html:

<div class="title-image-container">
    <div class="amz-image-container">
        <a href="" target="_blank">
            <img src="" alt="" class="amz-image">
        </a>
    </div>
</div>

If I don't set min-width, the container becomes too small or if I don't set the max-width, the image becomes too big.

So what is wrong setting min and max on same element of type "flex". I was told that this css code is completely wrong.
