What is Lazy Loading?
Imagine you’re at a buffet, and rather of piling everything onto your plate at once, you only grab what you need when you’re ready to eat it. That’s kind of what lazy loading does for websites. It waits to load images, videos, and othre resources until they’re actually needed, like when you scroll down to them. This can make your website load faster and run more smoothly.
Why Use Lazy Loading?
- Speed Up your Site: By not loading everything at once, your site can start up quicker, which is great for keeping visitors happy.
- Save Resources: It uses less data, which is especially helpful for people on mobile devices or with limited internet.
- Cut Costs: If your site gets a lot of traffic, lazy loading can help reduce the amount of data you need to serve, saving you money.
How to Implement Lazy Loading
Most modern web browsers make it easy to use lazy loading with a simple loading attribute. Here’s how you can do it:
- lazy: Waits to load the resource until it’s almost in view.
- eager: Loads the resource right away.
- auto: Lets the browser decide the best approach.
Tips for Best Results
- Set Image Sizes: Always specify the width and height of your images. This helps prevent the page from jumping around as images load.
- Fallback for Older Browsers: Not all browsers support the
loadingattribute. You can use JavaScript libraries like lazysizes to ensure lazy loading works everywhere.

javascript
const observer = new IntersectionObserver((entries) => {
entries.forEach((entry) => {
if (entry.isIntersecting) {
const img = entry.target;
img.src = img.dataset.src;
observer.unobserve(img);
}
});
}, {
rootMargin: '50px',
});
const images = document.querySelectorAll('img[data-src]');
images.forEach((image) => observer.observe(image));
