拡張機能の使用方法

Why use it? Browsers support a hierarchy of stacking contexts, rather than a single global one. This means that z-index values are often used incorrectly, and arbitrarily high values get set.

By Using Z-Context, you'll know:

- If the current element creates a stacking context, and why
- What its parent stacking context is
- The z-index value
