Let's know how you can install lazy load plugin in blogger

How to install the Lazy Load plugin in Blogger?

First, open  Blogger  > Click the Themes menu   > Click  Edit HTML  > Then find and add the code below before  </body>
Code 1

// LazyLoad
function loadScript(d){var o=document.createElement("script");o.src=d,document.body.appendChild(o)}function downloadJSAtOnload(){loadScript("[email protected]/lazyarlinas.js")}window.addEventListener?window.addEventListener("load",downloadJSAtOnload,!1):window.attachEvent?window.attachEvent("onload",downloadJSAtOnload):window.onload=downloadJSAtOnload;

For those friends who have already added the Lazysizes code, just replace the code with this version of

Code 2

// Lazysizes
var lazysizer=!1;window.addEventListener("scroll",function(){(0!=document.documentElement.scrollTop&&!1===lazysizer||0!=document.body.scrollTop&&!1===lazysizer)&&(!function(){var e=document.createElement("script");e.type="text/javascript",e.async=!0,e.src="[email protected]/lazysarline.js";var a=document.getElementsByTagName("script")[0];a.parentNode.insertBefore(e,a)}(),lazysizer=!0)},!0);
You can choose or use any one code of them.

The application is almost the same as in the post about Lazysizes, you only need to find everything img in the theme. The code will look like this:


Example :

<img src='//'/>

Add  class='lazy' for  Code 1  and  class='lazyload' for  Code 2  in the markup like this:

<img class='lazy' data-src='//' src='data:image/png;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs='/>

Change  src to  data-src and add  src='data:image/png;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs=' after  data-src

Or for this example:

<img expr:alt='data:post.title' expr:src='resizeImage(data:post.firstImageUrl, 280, &quot;300:200&quot;)' height='186' width='280'/>

So like this :

<img class='lazy' expr:alt='data:post.title' expr:data-src='resizeImage(data:post.firstImageUrl, 280, &quot;300:200&quot;)' height='186' src='data:image/png;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs=' width='280'/>

Do the above for all the img markup   on the theme. What if the img markup already contains a class? Then you only need to add  lazy or  lazyload after the first class, for example:

<img class='blogger lazy' data-src='//' src='data:image/png;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs='/>

When finished, save the theme and see the results on your blog.
