  readmore and readless toggle button

In this blog we will learn how to add a readmore and readless toggle button for webpage using Javascript.


The 'read more' button comes in handy when there is a more text and want to show some part of the text.
This is common in several websites like blogging sites, or when showing in profile description or to show course topics etc.
There will be a button, toggles between showing and hiding content as and when user clicks on.

By default, it is collapsed and shows ellipsis(..). When button clicked, it expands the content. As shown in the below picture.
