No JavaScript. No libraries. Just clean, responsive, modern sliders powered entirely by CSS.

✨ Why Use Pure CSS for Sliders?

JavaScript sliders are everywhere — but they often come with:

• Heavy dependencies
• Accessibility issues
• Slow rendering or layout shifts

In contrast, pure CSS sliders are:

• ⚡ Lightweight & fast
• 🧩 Easy to integrate
• 🛠️ Surprisingly powerful with the right tricks

In this post, you’ll get three modern slider types using only HTML + CSS — no JavaScript required.

✅ Live Demo: All 3 Sliders in One CodePen

🔁 1. Auto-Playing Infinite Slider

A smooth horizontal carousel that loops forever using keyframe animations.

<div class="slider">
  <div class="slide-track">
    <img src="..." />
    <!-- Repeat images to simulate infinite loop -->
  </div>
</div>

.slide-track {
  display: flex;
  animation: scroll 18s linear infinite;
}

@keyframes scroll {
  0%   { transform: translateX(0); }
  100% { transform: translateX(-50%); }
}

✅ Pros

• Auto-plays forever
• Clean and modern
• Zero JS

⚠️ Notes

• You need to duplicate the image set to simulate infinite looping

🎚️ 2. Manual Slider with Radio Buttons

Slide content by selecting radio inputs — no script needed.

<input type="radio" name="slider" id="s1" checked>
<input type="radio" name="slider" id="s2">

<div class="slides">
  <div class="slide"><img src="..." /></div>
  <div class="slide"><img src="..." /></div>
</div>
<div class="nav">
  <label for="s1"></label>
  <label for="s2"></label>
</div>

#s1:checked ~ .slides { transform: translateX(0); }
#s2:checked ~ .slides { transform: translateX(-100%); }

✅ Pros

• Fully accessible with keyboard/tab
• Clean CSS transitions
• Works well for small galleries or portfolios

🧠 Real-World Analogy

Think of it like flipping through radio stations — only one is “active” at a time. The :checked selector handles all the logic!

🖱️ 3. Scroll-Snap Horizontal Gallery

Drag horizontally on touch or mouse — CSS scroll-snap does the magic.

<div class="snap-slider">
  <div class="snap-slide"><img src="..." /></div>
  ...
</div>

.snap-slider {
  display: flex;
  overflow-x: auto;
  scroll-snap-type: x mandatory;
}

.snap-slide {
  scroll-snap-align: start;
  flex: 0 0 auto;
}

✅ Pros

• Native scroll behavior (touch + mouse)
• Smooth UX, minimal CSS
• No JavaScript at all

🌍 Great for

• Product previews
• Mobile-friendly image galleries
• Responsive portfolios
