The content icon is represented with squares that have symbols inside them to show the images that can be represented in the content. The other part of the content icon is a couple straight lines to represent written words.
This Content icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px.
