Idea of Todo List Icon
There are three equal length horizontal lines which are placed on top of each other with equal spacing between them and there are three tick marks which are of equal size towards the left side of each line. Also there is small spacing between each tick mark and the horizontal line.
This Todo List 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 6,200 icons, all in the same style and quality.
