Panic Relief

I have been suffering from anxiety and hyperventilation recently, so I have created this pure CSS animation to help me relax and relief the overbreathing syndrome.

The animation illustrates a breathing technique called "Square Breathing", which includes the following repeated steps, each for 4 seconds:

1. Inhale
2. Hold
3. Exhale
4. Hold

I hope this animation can help anyone who is becoming anxious or having a panic attack.
