Annotate by Garrett Knoll from Noun Project

Web annotation is the process of adding notes, comments, or other annotations to digital content on the web, such as web pages, PDFs, and other documents. Web annotation tools allow users to highlight and annotate specific parts of digital content, such as text, images, and videos, and share those annotations with others. Web annotation tools can be integrated with web browsers or other software, allowing users to highlight and annotate digital content directly within the context of the web page or document. Some web annotation tools also provide social features, such as the ability to share annotations with specific individuals or groups, or to view and interact with other users' annotations. There are also challenges associated with web annotation, such as ensuring the privacy and security of the annotations, and addressing issues related to ownership and intellectual property.
