There is a picture that needs to round the corners, but leave a shadow. Now the substrate under the picture with rounded corners and with a shadow, but on a white background and in size extends beyond the edges of the image. However, if you assign a transparent color to the box-shadow property, then the shadow itself will disappear - how can you solve the problem?
.owl-item { box-shadow: 0 22px 87px rgba(0, 0, 0, 0.3); opacity: 0.3; border-radius: 30px; } <div class="owl-item active center"> <div class="item"> <img src="http://placehold.it/350x150"> </div> </div>
