This Markdown 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. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,400 icons, all in the same style and quality.
This icon of Markdown is shown as a rectangle. The rectangle has slightly rounded edges. In the center of the rectangle on the left side is a large capital letter M, and next to that is a downward facing arrow.
