Sadece CSS ile slideshow yapmak

Bir HTML web sitesi için slide show/slayt gösterisi deyince akla ilk gelen şey JavaScript oluyor ancak bir CSS kompetanı olarak ben eğer basitçe yalnızca görseller görünecek ise JavaScipt’e ihtiyaç duymuyorum.

Yalnızca CSS kullanarak/Pure CSS Slideshow yapımı için aşağıda benim hazırladığım kodları kullanabilirsiniz.

main {
  height: 100vh;
  min-height: 30rem;
  cursor: pointer;
  position: relative;
  width: 100%;
  overflow: hidden;
}

.slideshows {
  background-color: #1116;
}
.slideshow {
  position: absolute;
  top: 0;
  left: 50%;
  width: 100%;
  height: 100%;
  transform: translateX(-50%);
}
.slideshow--hero {
  z-index: 3;
  left: 0;
  top: 50%;
  height: 85%;
  transform: translateY(-50%) skewY(-10deg);
  transform-origin: center;
  overflow: hidden;
  box-shadow: 0 0 1rem rgba(0, 0, 0, 0.25);
}
.slideshow--hero .slides {
  position: absolute;

  top: -10%;
  width: 100vw;
  height: 100vh;
  animation: 11s slideshow-hero-mobile -3s infinite;

Sadece CSS olduğu için daha hızlı ve kusursuz çalışacaktır. Ben bu uygulama için Unsplash’dan random resimler kullandım, siz kendi görsellerinizi kullanabilirsiniz.
