How to Create a Fullscreen Image Slider with Pure CSS

Fullscreen sliders are very trendy, and there are lots of cool examples all over the internet. Many of them are created with JavaScript, but we can create a nice slider with just using HTML and CSS. Let’s see how to create a cool and easy fullscreen slider with a bunch of CSS properties.

Create HTML

  • Use an <input> element with the type attribute to create a radio button. Also, add the id and name attributes.
  • Use a <label> element with a for attribute.
  • Use a <div> element with a class name.
<input type="radio" id="trigger1" name="slider" checked autofocus>
<label for="trigger1"></label>
<div class="slide n1"></div>

Add CSS

body,
html {
  padding: 0;
  margin: 0;
  width: 100%;
  height: 100%;
  text-align: center;
  overflow: hidden;
}
.n1 {
  background-image: url("https://images.unsplash.com/photo-1491438590914-bc09fcaaf77a?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=750&q=80");
}
.n2 {
  background-image: url("https://images.unsplash.com/photo-1556159992-e189f8e50104?ixlib=rb-1.2.1&auto=format&fit=crop&w=750&q=80");
}
.n3 {
  background-image: url("https://images.unsplash.com/photo-1511988617509-a57c8a288659?ixlib=rb-1.2.1&auto=format&fit=crop&w=751&q=80");
}
.n4 {
  background-image: url("https://images.unsplash.com/photo-1522202176988-66273c2fd55f?ixlib=rb-1.2.1&auto=format&fit=crop&w=751&q=80");
}
.n5 {
  background-image: url("https://images.unsplash.com/photo-1523240795612-9a054b0db644?ixlib=rb-1.2.1&auto=format&fit=crop&w=750&q=80");
}
input {
  position: absolute;
  opacity: 0;
  margin-top: 90%;
  cursor: pointer;
}
  • Make the <label> an inline-block element with the display property and continue styling it with the height, width, margin, border, border-radius, background-color, and other properties. Specify how long the transition animation should take with the transition-duration property.
  • Style the "slide" class. Translate the element along the X axis with the transform property.
  • Set a white background-color for the checked <input> and <label> elements.
  • Set a box-shadow for <label> elements.
  • Translate the checked input and successive "slide" class along the x-axis with the transform property.
label {
  display: inline-block;
  width: 12px;
  height: 12px;
  border: solid 2px white;
  border-radius: 999px;
  background-color: transparent;
  margin: 95vh 6px 0 6px;
  z-index: 2;
  cursor: pointer;
  transition-duration: .4s;
}
.slide {
  position: absolute;
  background-position: center;
  background-size: cover;
  background-repeat: no-repeat;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  z-index: -1;
  transform: translateX(-100%);
  transition-duration: .4s;
  opacity: 1;
}
input:checked+label {
  background-color: #ffffff;
}
input:focus+label {
  box-shadow: 0 0 0 2px #cccccc, 0 0 18px #fffffff;
}
input:checked~.slide {
  transform: translateX(100%);
}
input:checked+label+.slide {
  transform: translateX(0);
  opacity: 1;
}

Let’s see the final result of the fullscreen image slider with CSS.
