Native Lazy Loading Images and Iframes

what is lazy-loading

Lazy-loading means load this element on demand. We use the lazyloading technique to speed up the web page load time.

using lazyloading with images

Sample code for image element with lazy loading enabled.

<img width="" height="" loading="lazy" src="" alt="" />

The loading="lazy" is to load the image on demand. width="200" and height="400" to save the space for the loading image. src="" for the image url. alt="" to give a description for the image for accessibility purposes.

We us this CSS code snippet to make images responsive.

img {max-width:100%;height:auto;}

using lazyloading with iframe

Just add loading="lazy" to the opening element of iframe like this.

<iframe loading="lazy" ></iframe>
