This is a Code Filled icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,800 icons, all in the same style and quality.
This icon features a box with a bar on top of it. Inside of the box is a slanted line in the middle and there is a lesser than symbol on the left side of the slanted line. There is a greater than symbol on the right side of the line.
