holder.js not referenced or loaded in html document

I am new to Bootstrap. As i have started with DashBoard example in BootStrap. i see the below code in html page.

<img data-src="holder.js/200x200/auto/vine" class="img-responsive" alt="Generic placeholder thumbnail">

And i did a search of entire html code, no where i found holder.js being loaded. Can someone explain me from where does holder.js get loaded ? All i see is the above reference inside a image tag. But i am just wondering where or how will the browser be aware of holder.js

Solution

  • holder.js is just a client side image placeholder script and not part of Bootstrap nor necessary at all. It is used in development to put in generic placeholder images until you put in your own images

    holder.js

    You do not need to load docs.min.js for Bootstrap.
