Question: I have a strange problem on a small page I made.

When the content extends the height of the browser and I scroll down fast, the pixelated box appears for a split of a second and then goes away.

Why is this happening and how can I fix this?

Answer: 
```
typedef enum {Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday, Last} Day;
void DoSomething(Day day){
   // if day < Last ...
}

```
You could put a switch statement in your DoSomething. 

```
switch(day){
case Day.Monday:
     // something
    break
...
default: 
    // ignore or something

```
