Let’s create a Glowing Tube Loader using HTML and CSS. This project will feature a loader animation where a glowing “liquid” fills up a tube, providing a modern and engaging loading indicator.
We’ll use HTML for the basic structure of the loader and CSS to style the tube and animate the glowing filling effect.
Let’s get started on building the Glowing Tube Loader. Whether you’re new to web development or have more experience, this project offers a great way to practice CSS animations and create a visually engaging preloader. Let’s bring some glow to our loading screens!
HTML :
This code snippet creates a section for a loader that contains five individual sliders. Each <div class="slider"> represents a sliding element, and they are given a custom CSS variable --i to differentiate them. The --i variable allows for unique animations for each slider, making them stagger in their movements based on their index. When combined with the CSS from your previous code, these sliders will animate vertically with a hue-rotation effect, creating a visually appealing loading animation. The loaders are organized within a parent section classed as loader, which centers them on the page.

CSS :
This code creates a loader animation. The html and body are centered using flex with a light gray background. The .loader class centers its child elements horizontally. The .slider class defines the look of the sliding elements, giving each a white, cylindrical shape with shadow effects. The ::before pseudo-element creates a circle that moves vertically within the .slider from top to bottom using a keyframe animation called animate_2, which shifts the element’s position and changes its color gradually (with the hue-rotate filter). The animation repeats infinitely.

In conclusion, creating a Glowing Tube Loader using HTML and CSS has been an exciting and creative project. By combining HTML for structure and CSS for styling and animations, we’ve designed a modern loader that visually represents progress in a glowing and interactive way.
