如何使背景像顶部的SVG一样在顶部?

我一直在这个网站上工作。我正在尝试使横幅背景像底部的svg图像一样。我不想使用图片作为背景,所以我一直在使用CSS background-image。我使用的是剪切路径,因为它可以更轻松地隐藏图片的一部分。

有什么办法可以使左下角半径与直线圆角相交的点,所以它看起来像底部的SVG图像吗?

$cacheFile = 'cache' . DIRECTORY_SEPARATOR . md5($url);

if( file_exists($cacheFile))
{
    $omdb = json_decode(file_get_contents($cacheFile), true);
}
else
{

   $url = file_get_contents("https://www.omdbapi.com/?i=tt".$imdbID."&apikey=" . $omdbapi_key);
   file_put_contents($cacheFile, $url);
   $omdb = json_decode($url, true);
}

您可以使用伪元素并结合半径进行一些旋转来对其进行逼近:

header {
  position: relative;
  overflow: hidden;
  height: 800px;
  z-index: 0;
}

header:before {
  content: "";
  position: absolute;
  z-index: -1;
  top: 0;
  bottom: 0;
  left: 0;
  right: -200px;
  background-image: linear-gradient(315deg, #6c2aad 0%, rgb(44, 80, 199) 74%);
  border-bottom-left-radius: 35% 35%;
  transform: rotate(-18deg);
  transform-origin: left;
}

.header-bg {
  position: absolute;
  top: 0;
  bottom: 0;
  right: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

#banner-content {
  height: inherit;
  position: relative;
  display: flex;
  flex-direction: row;
  justify-content: center;
}

#banner-image-container img {
  position: absolute;
  left: 0;
  bottom: 50px;
}

#banner-image-container {
  align-self: flex-end;
  margin: 0 7%;
  height: 410px;
}

#right-side {
  align-self: center;
  margin: 0 7%;
  max-width: 420px;
  text-align: center;
  color: #FFF;
}

#right-side p:first-child {
  font-size: 30px;
  font-weight: bold;
}

@media screen and (min-width: 551px) {
  #right-side {
    align-self: center;
    margin: 0 7%;
  }
}

#banner-content img {
  max-width: 600px;
  width: 70%;
  display: block;
  margin: 0 auto;
}

@media screen and (max-width: 724px) {
  #banner-content {
    flex-direction: column-reverse;
    justify-content: flex-start;
  }
  #banner-image-container {
    align-self: center;
  }
}
