具有边界半径的圆角仅影响一侧

Question

我正在尝试重新创建它：

我正在使用SVG和Polygon，还有什么更容易的方法来固定边界半径吗？

<div class="showCaseVideo" style="background: none;">
  <svg width="100%" height="100%" viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="none" style="border-top-left-radius: 300px 70px; border-bottom-left-radius: 300px 70px; border-radius: 35px;">
	<defs>
		<linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
			<stop offset="0%" style="stop-color:#076FAD;stop-opacity:1"></stop>
			<stop offset="100%" style="stop-color:#28AADD;stop-opacity:1"></stop>
		</linearGradient>
	</defs>
	<polygon points="0,10 100,0 100,100 0,90" style="/*! display: none; *//*! color: white; *//*! stroke: white; */fill: url(#grad1);/*! display: M64.5 45.5 82.5 45.5 82.5 64.5 64.5 64.5 z; */" d="M64.5 45.5 82.5 45.5 82.5 64.5 64.5 64.5 z">
	</polygon>
</svg>
</div>

Answer 1

我会使用带有3d变换的伪元素。

.slanted {
  position: relative;
  perspective: 500px;
  width: 180px;
  height: 120px;
  z-index: 1;
  
  display: flex;
  justify-content: center;
  align-items: center;
  color: white;
  font-size: 2.4;
  font-weight: bold;
  font-family: sans-serif;
  
}

.slanted::before {
  content: '';
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: cornflowerblue;
  border-radius: 10px;
  transform: rotateY(-20deg);
  z-index: -1;
}

<div class="slanted">
  Slanted
</div>

Answer 2

发生的事情是您将svg元素的角而不是多边形的角弄圆了。在下一个示例中，我通过为角添加二次贝塞尔曲线来将多边形重新计算为带有圆角的路径。希望对您有所帮助。

svg{width:90vh}

<div class="showCaseVideo" style="background: none;">
  <svg width="100%" height="100%" viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="none" >
	<defs>
		<linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
			<stop offset="0%" style="stop-color:#076FAD;stop-opacity:1"></stop>
			<stop offset="100%" style="stop-color:#28AADD;stop-opacity:1"></stop>
		</linearGradient>
	</defs>
	<!--<polygon points="0,10 100,0 100,100 0,90" style="fill: url(#grad1);">
  </polygon>-->
    
    <path style="fill: url(#grad1);" d="M6.123233995736766e-16,20 Q0,10 9.950371902099892,9.00496280979001L90.04962809790011,0.9950371902099887 Q100,0 100,10L100,90 Q100,100 90.04962809790011,99.00496280979002L9.950371902099892,90.99503719020998 Q0,90 6.123233995736766e-16,80Z" />
</svg>
</div>

另一种选择是使用带有圆角的HTML元素，然后使用perspective，transform-style: preserve-3d;和transform: rotateY()旋转它。

在第二种情况下，文本也将被转换。
