圆形图像背景周围的透明CSS渐变

Question

我一直在尝试在图像背景周围实现透明的渐变效果（考虑白色），也许是绝对定位？，您可以想象我在谈论解释性绘画的含义。

You can create radial gradients in css with the radial-gradient function and make your elements rounded with border-radius .

 .transparent-gradient { width: 300px; height: 300px; border-radius: 50%; display: inline-block; position: relative; overflow: hidden; } .transparent-gradient img { min-width: 100%; min-height: 100%; vertical-align: middle; } .transparent-gradient::after { content: ""; background-image: radial-gradient(ellipse at center, rgba(255,255,255,0) 0%,rgba(255,255,255,1) 100%); width: 100%; height: 100%; position: absolute; top: 0; left: 0; } 

 <div class="transparent-gradient"> <img src="https://images.unsplash.com/photo-1530279281203-4c60af01ee58?ixlib=rb-0.3.5&ixid=eyJhcHBfaWQiOjEyMDd9&s=02b66d237286bcb2a071ed6c1e72adf3&auto=format&fit=crop&w=1950&q=80" width="400"> </div>
