Create a div with class="loader" as the loader. 2. Use CSS to set the width, height, border and rounded corners to form a circle, and visually rotate through border-top color differences. 3. Add a spin animation defined by @keyframes to keep spinning. 4. Optionally use flexbox to center the loader.
Creating a simple CSS loading spinner doesn't require any images or JavaScript. You can build one using just HTML and CSS with a few lines of code. Here's how to make a basic spinning circle loader.
Create the HTML structure
Start with a single div element that will act as the spinner. Give it a class name like loader for styling.
<div class="loader"></div>
Style the spinner with CSS
Use CSS to create a circular shape and apply a rotating animation. Set border properties to give it a spinning effect.
.loader {
width: 40px;
height: 40px;
border: 4px solid #f3f3f3;
border-top: 4px solid #3498db;
border-radius: 50%;
animation: spin 1s linear infinite;
}
@keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}This creates a border-only circle where only the top part is colored, giving the impression of rotation. The animation property makes it spin continuously.
Center the spinner on the page (optional)
If you want the spinner centered, wrap it in a container and use flexbox.
<div class="loader"></div>
Add this CSS:
.loader-container {
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
}That's it. You now have a clean, smooth-loading spinner. You can adjust size, color, speed, or shape depending on your design needs. Basically just tweak the width, border, or animation duration to customize it.

How to target the last child element in CSS?
Sep 24, 2025 am 02:26 AM
Use the :last-child pseudo-class selector to accurately locate the last child element in the parent container, regardless of its type. For example, li:last-child is used for the last item on the list, and *:last-child is suitable for any ending element. Unlike :last-of-type, :last-child only focuses on whether it is the last child node, while :last-of-type matches the last instance of a particular type. This method is widely supported and is suitable for scenarios such as removing unnecessary margins or highlighting the last item.
