### Overlay components
Bootstrap includes several components that function as an overlay of some kind. This includes, in order of highest `z-index`, dropdowns, fixed and sticky navbars, modals, tooltips, and popovers. These components have their own `z-index` scale that begins at `1000`. This starting number is random and serves as a small buffer between our styles and your project's custom styles.
Bootstrap includes several components that function as an overlay of some kind. This includes, in order of highest `z-index`, dropdowns, fixed and sticky navbars, modals, tooltips, and popovers. These components have their own `z-index` scale that begins at `1000`. This starting number was chosen arbitrarily and serves as a small buffer between our styles and your project's custom styles.
Each overlay component increases it's `z-index` value slightly in such a way that common UI principles allow user focused or hovered elements to remain in view at all times. For example, a modal is document blocking (e.g., you cannot take any other action save for the modal's action), so we put that above our navbars.

Equal-width columns can be broken into multiple lines, but there was a [Safari flexbox bug](https://github.com/philipwalton/flexbugs#flexbug-11) that prevented this from working without an explicit `flex-basis` or `border`. There are workarounds for older browser versions, but they shouldn't be necessary if you're up-to-date.
### Equal-width multi-line
Create equal-width columns that span multiple lines by inserting a `.w-100` where you want the columns to break to a new line. Make the breaks responsive by mixing `.w-100` with some [responsive display utilities]({{< docsref "/utilities/display" >}}).

## Responsive classes
Bootstrap's grid includes five tiers of predefined classes for building complex responsive layouts. Customize the size of your columns on extra small, small, medium, large, or extra large devices however you see fit.
