Being on fire covers half the screen. This pack pushes the on-screen flames down so you can see what you are fighting.
Unlike most low fire packs it leaves fire in the world alone: burning blocks, soul fire and nether fire keep their full height, because the pack gives block fire its own copy of the texture and only shortens the one the screen overlay uses.
The textures are small edits of Minecraft's default ones, so the pack sits on top of vanilla or under any other pack. Minecraft's original textures belong to Mojang.
