Border radius makes background image blurry-CodePudding

Why does border-radius makes background image blurry?

.orig,
.round,
.container,
.container::before
{
  content: "";
  width: 150px;
  height: 150px;
  background-size: cover;
  background-image: url("https://lh3.googleusercontent.com/IlhDxQVsR17dwwER5xYZJej867KrdSx0K5eyRP2RFP4eQJMD2pi0ZGBhrMOcajBUP9M54lpmIr90JecPUFGPaRe3sDZ82RvHBSw1rw-YJvQs7J8K3g=w1024-h683-n-l50-sg-rj");
  display: inline-block;
  position: relative;
}

.round,
.container
{
  border-radius: 10px;
}

.container
{
  background-image: none;
  overflow: hidden;
}


/* display text */
div::after
{
  content: attr(class);
  position: absolute;
  color: white;
  width: 100%;
  top: 0;
  display: block;
  text-align: center;
}

<div ></div>
<div ></div>
<div ></div>

Is there some kind of css parameter that can disable this effect?

CodePudding user response：

Try using image-rendering: pixelated on the image. This should tell to browser to display the image with crisp edges, rather than smoothing it out.
