This is a very small JavaScript library to create and animate annotations on a web page.
Elements can be annotated in a number of different styles such as:
– Underline (Creating a sketchy underline below an element).
– Box (This style will draw a box around the element)
– Circle (Draw a circle around the CSS element)
– Highlight ( Creates a highlight effect as if marked by a highlighter, this is example in this video)
– Strike-Through (Draw a hand-drawn line through an element creating a stroke-through
– Crossed-Off (use a crossed-off effect on an element.)
– Brackets (Create a hand-drawn bracket around a block like a paragraph of text on one or multiple sides of the block)
– Multiple lines (Ability to annotate inline content that can span multiple lines)

Please note that The Animation duration and delay can be configured, or just turned off.

One more JS example is available. This example shows the Annotation Group:

This provides a way to order the animation of annotations by creating an
annotation-group, just pass the list of annotations to create a group. When show()
is called on the group, the annotations are animated in order.
