### Fragment Shader Challenge

A fragment shader is ran once for every pixel contained in-between your geometry's vertices. Its purpose is to color in your mesh so you can actually see what it is you are rendering.

To create a fragment shader, you must assign a `vec4` `RGBA` value to an attribute called `gl_FragColor`.

Start by adding in the `gl_FragColor` attribute and assign it a `vec4` with an `R` value of `1.0`, a `G` value of `0`, and `B` value of `0`, and an `A` value of `1.0`.

```glsl
void main() {
}
```
